This proposed plan presents scientific needs for HIAPER consistent with the overall NSF emphasis on understanding and predicting the earth system. Proposed HIAPER capabilities, especially altitude capabilities to 50,000 feet and range capabilities of greater than 6000 nautical miles, match many of the observational challenges inherent in an emphasis on atmosphere, ocean, land, and ice interactions. The plan describes five specific tasks: Specifications, Aircraft Acquisition and Modification, Installation of Research Infrastructure, Instrumentation, and Preparation for Operations. ATD proposes extensive community review and oversight throughout the acquisition. In particular, ATD proposes to establish a new HIAPER Advisory Committee with majority membership from the university research community.
ATD will lead and provide most of the staff for the HIAPER effort. ATD will manage this project through a HIAPER team composed of ATD, NCAR and UCAR staff. The team will also include staff from NCAR science divisions such as the Atmospheric Chemistry Division and the Mesoscale and Microscale Meteorology Division and from UCAR units, including Corporate Affairs and Finance and Administration. ATD will hire a full-time project manager for the term of the overall acquisition. ATD will contract additional assistance from the USAF Commercial Aircraft Integrated Project Team, a group at Wright-Patterson Air Force Base with extensive experience in acquiring and overseeing the modification of commercial aircraft for Department of Defense and other federal aviation needs.
The overall process, from development of specifications through flight testing to research operations, will take approximately five years. Manufacture and modification of the airframe and development of advanced research instrumentation constitute the largest portions of that schedule. Sufficient definition of the research missions and payloads will occur early in the process to help specify structural modifications. Instrument development will begin early in the schedule to allow completion in phase with the availability of the modified, outfitted aircraft.
1. OVERVIEW AND RELATION TO NSF REVIEW CRITERIA
8. ESTIMATED COSTS AND BUDGETS
Section 2, Scientific Needs and Requirements for the High-performance Instrumented Airborne Platform for Environmental Research (HIAPER), addresses both review criteria. As described in that section and elsewhere throughout the document, we believe that the HIAPER acquisition responds to clear and substantial scientific needs and will enable a broad range of new scientific research.
Subsequent sections describe ATD's plans for managing the overall procurement and instrumentation processes. Efforts described in those sections also relate directly to the review criteria, especially to the broad impact of the overall HIAPER acquisition process. Sections 4.5 and 5.4 detail plans for instrumentation for HIAPER. A large portion of the instrument development effort will occur at universities with HIAPER funding. This burst of instrument development, coupled with challenging new design criteria, will invigorate development activities at universities and inject new technologies into these university laboratories as well as research aviation. In less than two years, 15 aircraft from other agencies and other countries have added the new NCAR Global Positioning System (GPS) dropsonde, with spectacular results. We project similar impacts from HIAPER-related instrument developments.
Section 3.2.1 describes communication capabilities of the new aircraft related to educational opportunities. We project that capabilities available as HIAPER comes on line will allow wide bandwidth connections to and from the aircraft during operations. The aircraft will function as another node on the next-generation internet, making operational information and instrument data available in classrooms and laboratories. Many students have monitored submarine and even Mars operations in real-time. HIAPER will bring airborne information and imagery to students at a variety of levels.

This section provides an overview of the science that drives
the need for HIAPER, including important issues related to:
|
Other important scientific challenges, evolving from research in polar, biological, and ecological programs, also require measurements of atmospheric processes and use of airborne remote sensing tools. A research aircraft that can cover a quarter of the earth's circumference in a single flight, that can carry modern instruments to remote regions, and that can reach stratospheric altitudes over much of the planet, will enable progress on an enormous range of long-standing, recent, and future scientific questions.
In the discussion that follows, we describe some research areas that will have (or seem likely to attain) high priority over the next several years and that HIAPER will serve. Common issues cut across these research areas: the need to reach the upper troposphere and remote oceanic and polar regions; the need to understand interactions between the upper troposphere and lower stratosphere; the need to understand clouds, chemistry and dynamics simultaneously; and the need to understand all aspects of the hydrological cycle. The topics discussed also share a direct relevance to life on this planet, through their connections to weather prediction, air quality and climate change.
On smaller scales, the upper portions of tropical and mid-latitude
storm systems often go largely unmeasured. Ground and airborne
Doppler radars provide some tracking of storm motions, but significant
aspects remain largely unexplored. These include: the dynamics and
microphysics of the upper parts of large storms; the influences of
these storms on high-level regional cloud systems, on upper
tropospheric water vapor distributions and on chemical processes; and
the regional and large scale environmental controls on these storms by
upper tropospheric conditions and processes. A modern mid-sized jet,
equipped with appropriate cloud physics instruments and with remote
sensors to detect in-cloud and clear air dynamics, will enable a
substantial step forward in understanding atmospheric dynamics.
At the most recent American Meteorological Society Cloud Physics
Conference, scientists discussed plans for a community research
initiative on ice microphysics. The initiative, yet to be named, will
focus on ice initiation and evolution, ice structure, crystal growth,
and precipitation development. Ice particles very likely play a large
role in heterogeneous chemistry in the upper troposphere. Current
NSF-supported aircraft provide no access to altitudes above 35,000 ft.
Current special-purpose aircraft, such as ER-2s or WB-57Fs operated by
National Aeronautics and Space Administration (NASA), cross through the upper
troposphere, but rarely operate within that region, and even more
rarely operate within clouds in that region. HIAPER, with capability
to reach at least 50,000 ft, will thus provide unique access to
ice-cloud regions throughout the global troposphere, excepting only
perhaps the uppermost regions during the summer in the tropics.
Targeting strategies identify areas several thousand kilometers
upstream of a given region that need enhanced observations 24-to-72
hours ahead of a forecast storm arrival. For Europe and North
America, these sensitive regions occur far westward, in largely
unobserved regions of the oceans. With the range to cross ocean
basins at many latitudes, and with an automated GPS dropsonde
capability, HIAPER will serve as an ideal platform for testing and
evaluating these flexible targeted observational strategies.
Eventually, targeted observations could improve forecasts of major
winter storm systems.
Improved water vapor fields require a mix of satellite, aircraft, and
ground-based measurement systems. Aircraft should provide accurate
in-situ validation sensors for the space and ground systems and carry
high-resolution remote sensing capabilities covering the full
troposphere. With new lidar-based in-situ and remote water vapor
sensing systems, HIAPER could provide synoptic-scale maps of water
vapor over land or ocean, high-resolution profiles covering full
daytime or nighttime cycles, and full tropospheric water vapor
profiles across all of North America or an equally large remote
region. No research aircraft today provides such capabilities.
Winter 1996-97 flooding events on the U.S. west coast underscore the
need for improved medium-range forecasting of amount and timing of
heavy precipitation associated with extratropical cyclones,
particularly for storm systems on the eastern edge of large oceans.
Improved short-term forecasts require improved understanding of
details of these storm systems, including frontogenesis, frontal storm
structure, storm-to-storm interactions, and storm momentum, heat, and
moisture transports. Observations of these storm systems require
aircraft with the capabilities envisioned for HIAPER: the range to fly
to distant weather; the capability to measure properties of the storm
system at many altitudes in the troposphere and lower stratosphere;
and the payload to carry a comprehensive instrumentation package.
These processes include: the full production and destruction terms for
tropospheric and stratospheric ozone; the emissions of reactive and in
some cases noxious materials by natural terrestrial vegetation or
oceanic microorganisms, biomass burning, and human activities; and
rates, reactions, and feedbacks involved in global carbon, nitrogen,
and sulfur cycles. In almost all cases, these chemical processes
involve scale interactions between local sources and regional weather
and hydrological conditions. They often involve important reactions
on regional scales, in topographic basins or within coastal
circulation systems, with transport of products to larger, even global
scales. Increasingly, large urban population centers produce not only
local but regional and continental air-quality problems. These
processes involve significant daily variations due to photochemical
cycles and to daily changes in circulation patterns. All the
processes interact significantly with other chemical, biological and
hydrological processes. Terrestrial emissions affect ozone, while
ozone effects plant growth, nutrient uptake, and subsequent emissions.
Nitrogen abundance affects carbon processing in terrestrial and marine
ecosystems. Storms modify the chemistry of boundary layer air and
transport products to higher altitudes. Precipitation processes move
atmospheric components to land or ocean. Understanding these
interactive processes across the planet requires an aircraft with
great range and wide payload flexibility.
Aerosols significantly impact the chemical properties of the
atmosphere. Like many chemical components, aerosols can evolve from
local oceanic or terrestrial sources and develop as a result of
reactions that occur on hourly or daily time scales. In the
atmosphere, aerosols continue to evolve and can disperse over global
scales in days to weeks. In the stratosphere, heterogeneous reactions
are a dominant mechanism for ozone destruction. In the troposphere,
aerosols play a significant role in acid rain production, and large
but unquantified roles in tropospheric heterogeneous chemistry, in
cloud production and modification, and in general precipitation.
Researchers have very little information about the transport of
aerosols from the troposphere to the stratosphere, especially in
tropical regions that may represent important sources of stratospheric
aerosols. Changing aerosol loads in the stratosphere, from human
activities or volcanic eruptions, may exert strong influence on the
heterogeneous chemical processes controlling stratospheric ozone
depletion.
Quantifying these enormously complex chemical processes requires
relatively "fast" yet highly specific instruments deployed over a full
range of local, regional, and global scales and over full diurnal or
nocturnal cycles. An aircraft with the range, endurance, altitude,
and payload capabilities of HIAPER will provide a significant increase
in capability for atmospheric chemistry and air quality research.
Ironically, aircraft themselves, particularly emissions from
commercial air traffic, represent a growing concern in air quality,
chemistry and climate change; accordingly we require observations
within and above air traffic lanes.
Regional deterioration in air quality already produces large health
and financial consequences. These effects occasionally spread to
continental and even hemispheric scales. For much of the world's
population, changes in air quality may represent the most immediate
and most negative aspect of climate change. The performance
capabilities envisioned for HIAPER and the advanced chemistry
instrumentation that will accompany it represent a unique and
important resource for regional and global atmospheric chemistry
research.
Currently, the direct roles of aerosols in absorbing and scattering
radiation and their indirect roles in cloud formation represent some
of the most challenging questions in cloud and particle microphysics,
in chemistry and in climate. With their wide altitude (surface to
stratosphere) and geographic (regional to global) distributions, their
wide variations in size, abundance and composition, and their intimate
dependence on atmospheric dynamics and atmospheric properties,
aerosols present one of the most difficult observational challenges in
atmospheric research. HIAPER with accurate radiation and water vapor
sensors, advanced particle probes and efficient aerosol inlets, lidar
remote sensing of backscatter and extinction, full tropospheric
altitude coverage, and wide geographic range, will provide an ideal,
literally unmatched, capability for aerosol and radiation research.
Increasingly, however, ocean-atmosphere research requires more than
just sea-surface temperatures and surface wind stresses. For example,
regions of extensive marine stratus clouds, often with distinct
diurnal variations in coverage and optical thickness, present a
challenge to climate and forecast models. A platform like HIAPER,
with the ability to reach and cover remote marine stratus regions, and
to measure fluxes and sea surface temperatures below, microphysics
within, and backscatter above these clouds, offers an important
opportunity for understanding the development and evolution of these
systems.
Ocean-atmosphere interactions also include significant trace-gas
fluxes between air and sea. Fluxes of some tracers, such as of
dimethylsulfide (DMS), represent an important source for the formation
of marine sulfate aerosols. Measuring DMS fluxes in the atmosphere
also provides information about the distribution, abundance and
nutritive status of microorganisms in the underlying ocean. The net
fluxes of other biologically-mediated compounds with important
greenhouse or ozone depletion effects, such as of methyl bromide,
remain largely unknown over large areas of the ocean. HIAPER, with
fast, sensitive detectors for CO2, DMS, and other important tracers,
and active and passive remote sensors for ocean color and ocean biota,
will provide an important supplement to ship-based measurements.
The use of automated sensor systems in ocean research grows rapidly.
Various types of these sensor systems follow water masses at
preselected or adjustable depths, profile over hundreds to several
thousands of meters on predetermined or downloaded schedules, and
measure currents within a fixed navigation array regularly or in
response to specific velocity changes. Increasingly, the systems
include sensors for biological and chemical components as well as for
temperature, salinity or velocity. All of the sensor systems
communicate to ship or shore, generally through satellite links when
the system resides at the surface. For specific research
applications, however, and especially during the development and
testing phases of many of these systems, having an aircraft to provide
communications links offers significant advantages. An aircraft such
as HIAPER, with range sufficient to fly over most ocean basins, would
provide increased bandwidth due to line-of-site links and offer the
ability to interrogate and redirect an array of sensor systems within
a few hour's time.
2.1 Weather
2.1.1 Atmospheric Dynamics
Physical dynamics in the upper troposphere play a large role in the
formation and evolution of large-scale circulation and storm systems.
Observations in this region will support research on tropopause folds,
on stratospheric intrusions, on dry-slot formation in mid-latitude
storm systems, and on a wide range of interacting and related
gravity-wave processes. These observations require measurements over
very large (1,000 km) scales, at altitudes well within the lower
stratosphere at mid-latitudes.2.1.2 Precipitation Physics
Many uncertainties remain in fundamental microphysical processes
involved in atmospheric precipitation. Particularly significant among
these uncertainties are understanding how precipitation grows through
warm rain processes and how ice forms and grows into precipitation.
Observationalists and modelers recognize an urgent need to improve
parameterizations of both precipitation processes in forecast and
climate models. Improved short-term precipitation forecasts and better
understanding of possible "acceleration" of the global hydrological
cycle leading to an increasing frequency of intense precipitation
events will have a major impact on human activities, particularly on
food production.2.1.3 Predictions On Short Time and Space Scales
Improvements in models and corresponding advances in
computing raise the possibility of high-quality, high-resolution
forecasts of, for example, extreme precipitation events. An important
part of planning for the USWRP has been consideration of the value of
improved forecasts of intense precipitation events. Such events
annually cost the U.S. 150 lives and an estimated $3.4 billion.
High-quality forecasts drive a need for high-quality observations.
USWRP observational priorities include targeted observations and
improved 3-D and 4-D water vapor fields.2.2 Atmospheric Chemistry
2.2.1 Atmospheric Kinetics And Photochemistry
Understanding the current atmospheric chemical composition, and
especially how the future atmospheric composition will evolve due to
changing concentrations of several important trace components,
requires a fundamental, quantitative understanding of individual
photochemical processes involving hundreds of short- and long-lived
components. For example, many quantitative details of OH-related
processes, especially of the production of OH by ozone photolysis,
remain undetermined, even though OH represents the primary "cleansing"
(oxidizing) agent for many sulfur, nitrogen, hydrocarbon, and halogen
emissions. Likewise, trends in global tropospheric ozone remain
unpredictable without better understanding of the kinetics and
mechanisms of photo-oxidation of primary biogenic hydrocarbons. All
these compounds and reactions occur throughout the troposphere,
interact with aerosols and ice particles in the upper troposphere, and
depend strongly on stratosphere-troposphere exchange of ozone and
water vapor. Understanding these processes requires a capability to
lift complex payloads to upper tropospheric altitudes over continental
as well as remote polar and oceanic regions.
2.2.2 Chemical Processes, Aerosols, and Air Quality
The complex chemical system of the atmosphere interacts internally,
especially within the troposphere and stratosphere, and externally
with other significant components of the earth system: the ocean and
oceanic biota, the land and terrestrial vegetation and populations.
Predicting changes to the chemical composition of the atmosphere, and
consequent effects on health and climate, requires improved
representation of chemical processes in climate and forecast models
and improved observations and quantification of major chemical
processes.2.3 Climate
2.3.1 Cloud Systems
The distribution, evolution, and properties of clouds play very large
roles in the earth's energy budget and hydrological cycle. Cloud
particles and the dynamics of cloud systems may also play large roles
in atmospheric chemistry. Clouds themselves couple closely with
local, regional, and large-scale atmospheric dynamics and in many
regions play an important role in air-sea interactions. Many U.S. and
international research programs focus on various aspects of clouds and
cloud distribution. Cloud research, and the need to model clouds
correctly, extends throughout the troposphere, from marine stratus to
high cirrus. The Cirrus Regional Study of Tropical Anvils and Layers
(CRYSTAL) draft science plan presents an urgent need to focus on upper
tropospheric cloud generation, regeneration and dissipation. Other
cloud research focuses on precipitating clouds in convective storms
and on non-precipitating layer clouds over a variety of coastal
regions. The study of all these aspects of clouds, in all these
important regions, across the full lifecycles of various cloud
systems, requires an aircraft with enormous range, great endurance,
the ability to explore the full troposphere and the flexibility to
carry a variety of in-situ and remote sensing instruments.
2.3.2 Radiation and Aerosols
Understanding the radiative energy balance of the earth system
requires a quantitative understanding of radiation transmission and
absorption within the atmosphere and of reflection or re-radiation
from the underlying land, ocean or ice surfaces. In the atmosphere,
temperature and three principal atmospheric constituents - clouds,
water vapor, and aerosols - have direct and substantial impact on
radiative transfers. Quantifying the influence of each of these
factors requires direct measurements throughout the troposphere in all
regions of the planet. Tropical regions (with moist boundary layers,
dry middle layers, periodic large storm systems and persistent
upper-tropospheric cirrus clouds) and polar regions (with complex
surface properties and cloud systems) present particular challenges.
Questions about ice microphysics and tropical cirrus clouds loom
especially large in attempts to understand and quantify cloud effects
on radiation budgets.2.3.3 Ocean-Atmosphere Interactions
Understanding climate and weather requires an understanding of air-sea
interactions in a variety of regions: in the tropical Western Pacific;
in the deep-water formation regions of the North Atlantic; in the
monsoonal regions of the Indian Ocean; along northern hemisphere storm
tracks; in the leads and ponds of the Arctic; and in the circumpolar
currents of the Antarctic. Moored and drifting instruments and ships
provide the backbone of observations, supplemented importantly by
satellites. Aircraft traditionally play a remote sensing role,
dropping atmospheric and ocean sensors and sensing sea surface
temperature. HIAPER's ability to cross ocean basins in a single
flight, its advanced infrared sensors and automated launching system
for next generation dropsondes and expendable bathythermographs, will
enable a broad range of oceanic observations.2.4 Other Scientific Opportunities
2.4.1 Polar Research
As described earlier in this section, improved understanding of
climate requires improved understanding of energy budgets and
hydrological processes in polar regions. The range of an aircraft
like HIAPER enables a large increase in atmospheric research
capabilities over polar regions, particularly suited to studies of
polar ozone. With appropriate remote sensing instruments, HIAPER
could also provide important information about other polar processes.
Advanced remote sensing techniques could allow determinations of ice
and snow properties, ice volume, and ice dynamics in the Arctic and
Antarctica. Remote sensors of ocean properties could allow
investigation of biological productivity in Arctic seas or Antarctic
margins; biological processes in these regions can have important
influences on global nutrient and carbon budgets. HIAPER measurements
could provide high-resolution maps of ozone distribution and UV
irradiance in polar regions, to aid in the understanding and
prediction of UV exposure for high-latitude marine and terrestrial
ecosystems and for human populations.
2.4.2 Biological and Ecological Research
Large-scale atmospheric factors (visible and UV radiation,
precipitation and humidity, lower tropospheric air quality) play
important roles in controlling the productivity of natural and managed
biological systems. Moisture and chemical emissions from these
systems in turn influence atmospheric processes. HIAPER should
support a wide range of regional and continental-scale measurements of
atmospheric properties and of fluxes between the surface and the
atmosphere. With appropriate remote sensing systems, HIAPER could
also provide mapping and surveying capabilities for a variety of other
large-scale biological and ecological factors: habitat extent or loss;
vegetation distributions; and ecosystem productivity, quality or
stress. HIAPER range and endurance should prove especially useful for
surveys and assessments of remote marine ecosystems.
2.4.3 Upper Atmosphere Observations
Ground-based observations of mesospheric elements such as Na, K, Li,
Fe, and Ca suggest that densities of these constituents exhibit
considerable variabilities related to seasonal and latitudinal
variations of the mesopause thermal structure. These upper regions of
the atmosphere may offer sensitive and early indications of global
climate change. Up-looking airborne lidars, deployed on HIAPER above
most of the tropospheric water vapor and clouds, could provide
information on the altitude and geographic extent of polar mesospheric
clouds as well as on the geographic variability of many mesospheric
constituents.
2.4.4 Satellite Calibration And Validations
Within the next five years, NASA will launch satellites and remote
sensors of the Earth Observing System (EOS). The EOS program depends
on a broad spectrum of research and validation from investigators
around the world. NSF-funded researchers will incorporate new
satellite measurements into their studies of climate, atmospheric
chemistry and atmospheric dynamics. All these space-based sensors
incorporate significant but largely unvalidated assumptions about
trace chemical constituents and aerosol abundance, distributions and
scattering properties. Extensive and reliable calibration and
validation requires aircraft underflights of satellite orbits, with
instruments traceable to absolute calibration standards. HIAPER's
altitude capability, payload flexibility and extended range will make
it an ideal platform for these missions. For example, HIAPER will be
able to fly long flight segments that coincide with a single satellite
ground track or that cross multiple tracks, enabling maximum
intercomparison between aircraft and satellite measurements.
3. Planning Environment

The National Oceanic and Atmospheric Administration (NOAA) continues to operate two P-3 aircraft for hurricane reconnaissance and general research. Those aircraft generally do not operate above 30,000 ft. NOAA has one of the rare new aircraft in the U.S. research fleet in their Gulfstream-IV, which plays a substantial role in NOAA's hurricane and winter storm missions. The NOAA G-IV requires additional infrastructure to expand its research capabilities.
Many European countries operate small turboprop or jet aircraft, with very limited range, payload and altitude capabilities. The United Kingdom has a C-130 with range and payload capabilities similar to NOAA's P-3s and the C-130 at NCAR. French plans for aircraft modernization seem likely to continue to focus on small turboprops. The Germans have discontinued work on their Strato-2C. Several European research groups lease time on a Russian aircraft to obtain very high altitude capability similar to that of an ER-2 or a WB-57F.
In summary, the U.S. fleet has several highly capable general-purpose
aircraft and a few specialty, very-high altitude platforms, but
nothing that provides the range, altitude and payload capabilities
envisioned for HIAPER. In general, the U.S. agencies have had very
few opportunities for serious modernization plans other than those
provided by the NOAA Gulfstream-IV and by HIAPER. International
aviation groups would have to consolidate their current efforts to
develop a plan for an aircraft of the magnitude of HIAPER. Thus,
HIAPER represents a significant and much-needed step forward
domestically and internationally.
NCAR, other national laboratories, and many university groups already
explore these new technologies. The entire HIAPER infrastructure will
incorporate these emerging technologies at the onset and through
flexible upgrade planning. The HIAPER development occurs at an
opportune time to stimulate inclusion of these new technologies into
research instrumentation.
NSF designated a modern jet aircraft as a high priority acquisition in
various planning documents. A strategic plan for atmospheric
sciences, produced jointly in 1994 by the Division of Atmospheric
Sciences (ATM) and UCAR,
described scientific justification for a mid-sized jet and listed a
new jet, new supercomputing and a new incoherent scattering radar for
a polar cap observatory as highest priorities for geoscience facility
upgrades. Three recent long-range plans for NSF's Geosciences
Directorate (1995 to 1999, 1997 to 2001 and 1998 to 2002) call for
upgrades to atmospheric observing facilities; the most recent plan
explicitly identifies the need for a mid-sized jet. The NSF decision
to request funding for HIAPER thus derives from and responds to
long-recognized needs among a wide range of atmospheric science
researchers. NCAR has played a central, catalytic role in developing
community consensus.
On behalf of the scientific community, ATM, working with ATD, produced
a Project Development Plan (PDP) for a modern, mid-sized,
high-altitude jet. The National Science Board (NSB) endorsed that
plan in August 1997. Now, NSF has requested that NCAR, in its
capacity as a Federally Funded Research and Development Center,
undertake the overall acquisition of that aircraft.
3.1.1 NSF Aircraft
NSF currently supports two large research aircraft at NCAR: an aging
Electra and a relatively modern refurbished C-130. Figure 1 shows the
altitude and payload capabilities of these and other NSF aircraft
along with projected capabilities for HIAPER.3.1.1.1 NSF's
Electra at NCAR
The Electra has a modern data system and will soon have satellite
communication systems. With parts from a spare Electra acquired by
NSF from NASA, ATD can continue to operate the Electra for several
years. Soon, however, we must replace the Electra and transfer the
Electra Doppler Radar (ELDORA) to another platform. For engineering,
scientific, and operational reasons, ELDORA should go on a P-3,
operated by NCAR or by another agency. All planning in this document
assumes that we will cease operating the Electra as HIAPER comes into
service.3.1.1.2 NSF's
C-130 at NCAR
The C-130 will provide reliable support for a wide variety of payloads
and a broad range of missions up to altitudes of 28,000 ft for at
least the next two decades. It will carry large payloads and provide
unique infrastructure to atmospheric chemistry, cloud physics and
radiation, large-scale surface flux and various remote-sensing
missions. ATD will implement specific upgrades to further improve the
infrastructure of this highly capable aircraft. At a minimum these
upgrades will include:
3.1.1.3 Other NSF-supported Aircraft
The University of Wyoming King Air,
partially supported by NSF, provides a good payload capability for
boundary layer, atmospheric chemistry and other missions. The King
Air should provide at least another decade of very useful service. A
T-28 storm penetration
aircraft, operated by the South Dakota School of Mines and Technology
with NSF support, has a limited lifetime. NSF will determine the need
for a replacement penetration aircraft over the next several years.

3.2 Technological Developments for Modern Research Aircraft
3.2.1 Miniaturization and Digital Technologies
The growth in personal digital devices, from cell phones to digital
cameras to GPS receivers, drives important trends in cost, size and
capabilities of small signal processing and data storage capabilities.
Reductions in size, weight and power consumption feed directly into
the design and implementation of HIAPER instrumentation. For example,
new GPS chips that incorporate full signal processing into the sonde
itself will allow fully automated operation of GPS dropsondes
from HIAPER, thereby reducing the need for on-board electronics and
operator. The HIAPER data system will use small flash card or
miniature hard drive memory technologies derived from digital cameras
to replace central tape drives, again saving space while reducing
power consumption and weight. Commercial needs and developments will
produce lower-cost, higher-powered laser sources over a wide range of
wavelengths. Tunable diode laser technology will enable precise
measurements at water vapor and atmospheric trace gas wavelengths.
Sensitive arrays of charge-coupled devices may supplant conventional
optical detectors.3.2.2 Communications
A modern research aircraft in flight should "look" and perform like
any other node in the global communications system. It should have a
phone number, an internet address and a real-time web page. It should
provide easy and rapid voice, data and imagery transmission over all
networks. Today, many aircraft provide air-to-ground and
ground-to-air phone services. Anybody can follow the instantaneous
progress of any domestic commercial flight via the web. By the time,
or shortly after, HIAPER enters service, students will have the
ability to monitor a flight and view data from their classrooms and
laboratories. Automated instruments will communicate with
ground-based controllers. All modern communications technologies push
in these directions. Growth in NCAR and UCAR capabilities in data
processing, data distribution, and information management and
technology, through ATD, UCAR's UNIDATA program, and other groups,
will match the growth in commercial technologies and services and
allow HIAPER to take full advantage of new and expanded communication
systems.
3.3 Community Planning for a Mid-Sized
Jet Aircraft
Together, NCAR and the university research community have engaged in a
long and thorough discussion of needs and options for next-generation
aircraft. From as early as 1982, a series of community reports on
research aircraft have consistently and unanimously identified
compelling scientific need for a platform with the altitude and range
capabilities of a modern mid-sized jet aircraft. Two NCAR Technical
Notes, published in 19891 and 19922, reported
community discussion of aircraft options and community consensus on
capabilities needed in a mid-sized jet. Twice, NCAR convened
independent panels of university researchers to review the plans
reported in these Technical Notes. In 1989 and again in 1992, those
review panels urged NCAR and NSF to acquire a mid-sized jet.4. Project Organization and Management
Readers will find the following in this chapter:
|
NCAR plans the overall HIAPER effort to meet community needs. Meeting those needs requires extensive community involvement. The university community interacts with NCAR at all levels, from the UCAR Board of Trustees and various UCAR committees to day-to-day scientific collaboration among university and NCAR scientists. The 1996 NSF panel that reviewed NCAR found that
This pattern of broad community oversight and specific community
interaction will guide all aspects of the HIAPER procurement from
acquisition through instrumentation to operation.
4.1 Project Organization and Staffing
A HIAPER Integrated Project Team (HIPT) will undertake the actual work
of acquiring HIAPER. Primary members of HIPT will include the Project
Leader, Project Manager, Scientific Coordinator, technical and
scientific project staff from ATD, NCAR, UCAR, and advisors from the
U.S. Air Force (USAF) Commercial Aircraft Integrated Product Team
(CAIPT). HIPT will interact with community advisory and oversight
groups including a newly-commissioned NSF Oversight Committee (NOC)
focused on fiscal, contractual and business-related matters and a new
NCAR HIAPER Advisory Committee (HAC) focused on scientific and
technical matters. The exact composition of HIPT and its interactions
with oversight groups and the community will evolve according to task
and need, but HIPT will remain under the direct leadership and
guidance of the Director of ATD, David Carlson, who reports to the
Director of NCAR, Robert Serafin. Final responsibility for decisions
on selection of an aircraft source and on award of instrumentation
contracts lies with the NCAR Director. Key positions thus include the
NCAR Director, ATD Director, HIAPER Project Manager, HIAPER Scientific
Coordinator, UCAR Associate Vice President for Business Services, and
USAF CAIPT leader Jim Warren. The Supplementary section provides
biographical information for Serafin, Carlson, Reaves, and Warren.
Figure 2 provides a schematic summary of these groups.
4.2 HIAPER Integrated Project Team
The HIPT will reside within ATD at NCAR. ATD includes a Research
Aviation Facility (RAF), a Remote Sensing Facility, a Surface and Soundings System Facility, and Research Data and Design and Fabrication
(DFS) services. Staff from all of these groups
will contribute to the HIAPER effort.
The HIPT will include eleven permanent members (Figure 3). A full-time project manager will oversee and coordinate all procurement-related tasks (Tasks 1 and 2, Define Specifications and Aircraft Acquisition, detailed in Sections 5.1 and 5.2). The Project Manager, not yet selected, will have experience in aircraft procurement, modification and operations. She or he will have direct responsibility for interactions with the USAF CAIPT.
The HIPT will include a Scientific Coordinator. That person will have responsibility to plan and lead various workshops (see below) and to ensure effective interaction with technical advisory groups and the HAC. In particular, the Science Coordinator and ATD Director will work to include scientists from outside of traditional atmospheric research areas in various HIAPER planning activities. One person from the UCAR Contracts Office will devote full time to the HIAPER effort, with help from other UCAR contract and procurement staff as needed. The ATD Administrator will oversee budget monitoring and reporting functions. Table 3 lists all permanent HIPT members and their primary responsibilities.
The USAF CAIPT has extensive experience in the acquisition of commercial aircraft for the armed forces, and has assisted other federal agencies in such activities. The CAIPT seeks "to acquire and support commercial aircraft systems in partnership with customers by using innovative and streamlined acquisition practices to provide best-value products to satisfy customer's need." The CAIPT staff includes some of the most expert members of the USAF acquisition community, with extensive experience in federal acquisition processes as well as in USAF and civil domestic and international air operations. CAIPT will provide expertise in acquisition, certification, logistics, operations, contracting, and scheduling to the HIPT. Section 7 describes CAIPT experience and qualifications.

Throughout the acquisition, instrumentation, and preparation of HIAPER
for operations, the cumulative UCAR/NCAR/ATD effort, including
supporting efforts from CAIPT, will exceed 60 full-time equivalent
(FTE) over five years. Table 4 summarizes the combined FTE effort of
the many individuals involved in HIAPER tasks.
The members of the HAC will participate in workshops and other
advisory group processes developed by the HIPT. In particular, the
HAC will work with the HIPT Scientific Coordinator to ensure effective
community involvement in key aspects of HIAPER planning.
The HAC will endorse guidelines for instrument development, covering
desired capabilities and size, weight, and power constraints. Working
from recommendations provided by technical advisory groups and review
panels, the HAC will recommend highest priority instrument
developments.
UCAR provides a modern on-line cost accounting system with full
information access. ATD processes the UCAR information through a
web-based access and monitoring system. HIAPER managers,
administrators, project leaders and oversight groups can each take
advantage of fast electronic access to HIAPER financial information:
expenditures to date, projected expenditures, cost to completion, and
breakdowns of all expenditures and estimates by cost category (salary,
travel, equipment, etc.) and by task and sub-task.
Early in 1999, ATD will convene an airborne instrumentation workshop
to develop community priorities for measurement capabilities related
to primary scientific missions of the aircraft. A subset of attendees
from that workshop will develop: a composite set of needs for primary
(always on the aircraft) instrumentation; preliminary needs for
specialized instruments; and desirable airframe modifications.
Recommendations from this workshop summary group, particularly for
desirable structural modifications driven by instrument needs, will go
to the HAC for review and endorsement in time to play a useful role in
the preparation of a draft Request for Proposal (RFP).
After awarding a contract and setting final specifications for
structural modifications, ATD will convene a second instrumentation
workshop to discuss guidelines, needs, and opportunities for special
research instruments, HIAPER-compatible instruments deployed according
to project needs. The research instrument guidelines will include
space, weight, and power requirements, as well as requisite data
format, processing and transmission capabilities. The HAC will review
these instrumentation guidelines. These guidelines will feed into the
instrumentation RFP process.
Late in the acquisition process, as instrument capabilities and
operational schedules become clear, ATD and OFAP will host a HIAPER
users' conference, to discuss all aspects of operations, payload,
instrumentation, communications, mission planning and data quality. A
web-based report from this workshop will guide a wider audience of
potential users in their planning for future HIAPER research missions.
Solicitation of Proposals: Using instrument guidelines endorsed by the
HAC, UCAR will solicit proposals from the community. The solicitation
will explicitly allow preliminary funding for potential
instrumentation that requires further design and evaluation. The
solicitation will invite proposals from universities, NCAR,
universities in partnership with ATD, each other, or industry and from
other national and international laboratories. ATD's design and
fabrication group will provide design assistance and fabrication cost
estimates to instrument developers who desire such assistance. We
will require each instrument proposal to specify long-term
arrangements for instrument and data support.
Review and Evaluation: ATM Program Managers will conduct a standard
NSF merit review of all proposals. The Program Managers will present
results of those reviews with their recommendations to a special
review panel focused on HIAPER instrumentation. Panel recommendations
will then go to the HAC for final review and recommendation. The HAC
at this point should include participation from ATM Program Managers.
Contract Award: UCAR, in consultation with NSF, will issue contracts
for each instrument development, consistent with the recommendations
of the HAC. These contracts will include specific performance
expectations and schedules and will specify design guidelines and
restrictions, acceptance testing, long-term operations and calibration
support, ownership and intellectual property rights, and data rights
and responsibilities. These contracts will cover instrument
development through an initial testing and deployment period; they
will not pay for on-going operations or future research. Where
appropriate, instrument contracts may set specific standards and
procedures for accepting the instrument for flight testing.
Project Monitoring: The HIPT and appropriate technical advisory groups
will monitor designs and progress and report all such information to
the HAC and the NOC. ATD's aviation group, RAF, will provide
appropriate assistance regarding airworthiness requirements, options
for minimizing weight and power, and integration with the HIAPER data
system. Most projects will include a specific design review by ATD,
HIPT, and other experts. Subsequent performance milestones may
include demonstration of measurement accuracy on the ground,
certification of airworthiness and safety, and definition of
calibration and operational procedures.
Deployment and ownership of primary instruments will become the
responsibility of ATD and should require only occasional interactions
with the developers for troubleshooting or for issues related to
calibration. For specialized instruments, initial deployments may
require assistance and participation from the developers, who may also
assume initial data processing and distribution responsibilities.
Eventually, each special research instrument must revert to long-term
support arrangements as specified in the development contract.
Instruments developed with HIAPER funding must provide a plan for data
validation and for timely provision of data to ATD.4.2.1 Other Staffing
To supplement activities of the HIPT, ATD and NCAR staff will provide
very substantial additional effort on many aspects of the overall
HIAPER effort. The NCAR Advanced Study Program Director, William (Al)
Cooper, will continue to play a leading role in the development of
community plans for research instrumentation. Scientists from NCAR's
Atmospheric Chemistry, Mesoscale and Microscale Meteorology, and
Climate and Global Dynamics divisions will participate in community
planning for instrumentation. The ATD Assistant Director will support
the ATD Director throughout the procurement. Engineers and
technicians from ATD will work on HIAPER research infrastructure,
instrumentation, and system integration and testing.
4.2.2 Master Schedule
Figure 4 lays out the overall schedule for HIAPER
activities. Overall, the acquisition covers five years. We have
assumed two years from award of a contract to delivery of a modified
aircraft. Changes in that schedule will produce changes in the
schedules for all subsequent tasks. Significant effort, especially in
community planning, occurs in FY 1999, toward a goal of issuing a
contract for an aircraft early in FY 2000.
4.3 Oversight
4.3.1 NSF Oversight
The NOC, as specified in the HIAPER Memorandum to the NSB (provided
separately to reviewers), will review and approve major procurement
actions and other HIAPER activities to ensure compliance with the
policies and responsibilities specified by the UCAR-NSF Cooperative
Agreement and, in particular, by the HIAPER Scientific Program Order
(SPO). The NOC will receive and review the various in-progress and
final reports of the HIPT. It will include members from several NSF
units: Budget Division; Grants and Contracts; Division of Contracts,
Policy, and Oversight; Office of General Council; Office of the
Assistant Director for Geosciences; and the UCAR and Lower Atmospheric
Facilities Oversight Section (ULAFOS) in ATM.
4.3.2 NCAR and UCAR Oversight
The HAC will review the work and recommendations of the HIPT and
advise the NCAR Director on actions and responses. In particular,
recommendations on aircraft platform, source, and major structural
modifications will come from HIPT to the HAC for discussion, review
and endorsement. HAC will include three scientists from the
university community, two NCAR scientists or directors of NCAR
scientific divisions and representatives from NSF and from NSF's
Observing Facilities Advisory Panel (OFAP). Members of the HAC will
use their broad experience to guide HIAPER development in directions
that ensure maximum benefit for a wide group of users. The HAC,
reporting through the NCAR Director, will provide an oversight
function on behalf of the UCAR President, Richard Anthes, and the UCAR
Board of Trustees.4.3.2.1 Financial Oversight
Funding for HIAPER will occur through a special SPO as part of the
NSF-UCAR Cooperative Agreement. To ensure regulatory compliance,
enhance current administrative policies and procedures and provide a
consistent methodology for applying existing rules to various aspects
of the HIAPER acquisition, UCAR may issue special guidelines to cover
certain HIAPER procedures or clarify information already in the
Cooperative Agreement. These HIAPER guidelines will derive from and
be consistent with specifications in the SPO and other provisions of
the Cooperative Agreement. UCAR will set up special accounts to cover
HIAPER activities.4.4 Community Involvement
Members of the research community, including researchers from
disciplines outside atmospheric sciences, will have multiple
opportunities to advise and otherwise participate in the development
of HIAPER plans and the development of HIAPER instrumentation. The
HAC, described above, represents one primary mechanism for community
involvement and oversight. Other mechanisms include participation in
various technical advisory groups organized during specific aspects of
the acquisition process, information exchange with the OFAP,
participation in various surveys and workshops and development of
HIAPER instrumentation (Section 4.5).
4.4.1 Technical Advisory Groups
These groups will provide technical advice on desired capabilities,
desired structural modifications, and on desired primary and
specialized instrumentation. Some groups will consist of experts
gathered for specific discussions, such as, for example, the workshop
summary groups for modifications and instrumentation, discussed in the
next section. OFAP, a group of community researchers which meets
regularly to evaluate requests for use of NSF's observing facilities,
will hear regular reports on HIAPER activities from the ATD Director,
Project Manager or Scientific Coordinator. Because OFAP will
eventually evaluate requests for HIAPER usage, the OFAP members can
serve as valuable mechanisms for advice and for informing the larger
community about HIAPER plans, progress and schedules.
4.4.2 Surveys and Workshops
ATD conducted a survey of community needs and priorities for HIAPER in
the summer of 1998. That survey went to approximately 150 potential
users across a wide range of research specialties covering geo- and
environmental sciences. More than one third of those contacted
responded. Responses came from: university researchers (66%); NCAR
researchers (17%); and other national laboratories (17%). We discuss
results from this survey in Section 5.1 under Task 1, Defining
Specifications. ATD will request additional information from this
list of potential users as needed during the course of HIAPER
acquisition. As HIAPER plans and schedules become better known, ATD
will work with NSF program managers within and outside the Geosciences
Directorate to develop a broader list of potential users for
additional survey and information purposes.4.5 Instrumentation
ATD, working with the HAC, will undertake extensive community
involvement in developing instrumentation plans for HIAPER, primarily
through the two community workshops described above. The community,
working independently or with ATD, will carry out a large fraction of
the specific instrument developments. Section 5.4 provides extensive
descriptions of desirable primary instruments and of options and
opportunities for special instruments. Section 5.4 also discusses
specific mechanisms by which ATD, NCAR, and university investigators
can cooperate on all aspects of instrument planning and development.
Here we discuss the community-based process for selecting primary and
specialty instruments for HIAPER.4.5.1 Identifying and Selecting Candidate Instruments
The first community workshop will focus on primary instruments and
essential modifications, and the second on specialty instruments. We
intend that the HIAPER-specific funding for instrumentation requested
in this plan will support primarily those instruments designed
specifically for easy installation on and integration with HIAPER
research infrastructure. However, we recognize that a flexible
research infrastructure on HIAPER must allow deployment of highly
specific user-produced research instruments that do not fit a
'plug-and-play' model. HIAPER funding could also support the
modification of existing instruments or the combination of existing
instruments with an intermediate infrastructure to allow integration
with HIAPER. We propose the following steps to select and manage
instrument development projects. Please note that the solicitation,
evaluation and selection processes would occur once or perhaps twice
during the first and second years of the overall HIAPER acquisition.4.5.2 Testing, Evaluation, and Deployment
RAF will collaborate with instrument developers on testing as
specified in each contract. Where possible, such tests should include
intercomparisons and traceable calibrations. Each instrument
development should include an explicit characterization of measurement
uncertainty, preferably following uncertainty analysis methods adopted
by engineering societies such as the American Society of Mechanical
Engineers.
In this section we describe:
The total estimated costs for Task 1, in 1998 dollars, are summarized below: |
| Task 1: Requirements | FY 1999 | FY 2000 | FY 2001 | FY 2002 | FY 2003 | Total |
|---|---|---|---|---|---|---|
| (8.75 FTE) Total | 751,000 | 0 | 0 | 0 | 0 | 751,000 |
Respondents listed altitude as the most important capability for
HIAPER, ahead of endurance, payload, and floor space. Figure 5
presents these overall preferences while Figure 6 gives details of
preferred capabilities in each of the above categories: altitude,
endurance, range, payload, and floor space. The survey recipients
were given probable HIAPER characteristics as guidance, as well as
details of the capabilities of current NCAR aircraft for comparison.
Based on this information, the respondents clearly feel that their
scientific intentions require high-altitude, long-range capabilities.
This initial survey represents the first phase of our outreach for
broad-based scientific community input on HIAPER capabilities.
We start defining requirements by using the community survey
results. These depart only slightly from preliminary NSF and NCAR
descriptions of HIAPER as contained in early planning documents. In
summary, they are:
The determination of minimum requirements and desirable capabilities
of the aircraft will be the first step in the process of analyzing for
best value. A ranked and weighted scale of desirable capabilities will
be created to establish a relative value of these attributes. This
scale will give vendors insight into the priorities of the desirable
capabilities, will enable them to make appropriate business decisions
concerning their offers, and will also be used to perform a
cost-benefit analysis of priced options.
With the above information, we will conduct a two-phased approach, as
described in the next two sections, to finalize the set of minimum
requirements and desirable capabilities to be included in the RFP.
These conferences will also provide offerors an opportunity to provide
and discuss their comments on the draft RFP. Further, the site visits
will allow the acquisition team to see the offerors' facilities, meet
their staff, and gain a better understanding of their manufacturing
and modification (completion) capabilities and processes.5.1.1 Community Priorities
As mentioned in Section 4.4.2, ATD conducted a survey of community
intentions for HIAPER use and preferences for HIAPER capabilities.
This survey was sent to scientists covering a broad range of
sub-disciplines in lower atmospheric, upper atmospheric, oceanic,
earth, and biological science. Overall, the research planned by the
respondents largely echoes the scientific needs described in the
previous chapter. Respondents most frequently listed:
cloud-aerosol-radiation interaction studies; cloud microphysical
studies related to precipitation and electrification; gas-phase and
heterogeneous upper tropospheric chemistry; convective storm dynamics
and convective influences on chemical and water vapor distributions;
and air-sea interaction and evolution of marine cloud systems. In a
majority of cases, users wanted access to remote oceanic and to
tropical regions.
5.1.2 Defining Minimum Requirements and Desirable Capabilities
Known capabilities of modern high-altitude commercial jets provide
range, altitude, and payload capabilities to meet a large majority of
needs as expressed in the survey. Moreover, such aircraft will
provide vastly more capability than any current NSF aircraft, and
perhaps more overall versatility than any current or planned U.S. or
international research aircraft. The acquisition process and
particularly the setting of minimum requirements and desirable
operational capabilities must result in a platform that can serve the
maximum number of important scientific needs.

Working from mission specifications developed as part of earlier
community mid-sized jet planning efforts, and from mission
specifications that guided the recent NOAA procurement of a
Gulfstream-IV, the HIPT will develop a draft set of mission scenarios
for review at the first community instrumentation workshop. The
workshop summary group (Section 4.4.2) will refine these mission
scenarios, define a primary instrumentation package for each mission,
and develop the resulting minimum requirements, desirable operational
capabilities, and primary instrumentation lists. The HIPT will
incorporate these recommendations into an initial HRD. After review
by the HAC, HIPT will distribute the preliminary HRD to the community
and to industry for consideration and comment. Subsequent versions of
the HRD incorporating community and industry comments will eventually
become part of the preliminary RFP.5.1.3 Ensuring Competition
Ensuring competition is a goal of practical and ethical importance.
We will solicit multiple responses to the HIAPER RFP from industry to
provide competition and thus maximum capability in the selected
aircraft. For this reason, the minimum requirements for HIAPER must
be set at a level that will encourage responses from prospective
vendors. Specifically, the minimum requirements must be set so that
at least two commercially available aircraft can meet them, and thus
ensure that at least two bids are possible. This will require that
the HRD specifies realistic minimum requirements consistent with
available aircraft. Extended or enhanced capabilities desired for
HIAPER will influence the overall selection process through
value-added, capability tradeoffs as described below.5.1.4 Defining Tradeoffs and Analyzing Best Value
Selection of best-value alternatives for HIAPER will require
capability tradeoffs up to the point where the marginal cost for a
desirable capability that exceeds requirements loses its relative
value.5.1.5 Vendors' Conference
This conference will be convened at NCAR's facilities in Boulder and
Broomfield, CO. It will be designed to give the offerors a better
understanding of NCAR's mission and capabilities through first-hand
exposure to NCAR's aircraft operations, aircraft maintenance,
engineering design and fabrication, and instrumentation support
activities, and will include presentations and facility tours. This
conference will also give offerors an opportunity to get answers to
questions and to provide comments on the preliminary minimum
requirements and desirable capabilities of the aircraft, as well as on
HIAPER management and contracting strategies.5.1.6 Configuration Definition Conferences
These conferences will be held after the draft RFP release at the
facilities of each original equipment manufacturer (OEM) and/or
offeror. The primary purpose of these meetings will be to give the
acquisition team an opportunity to get answers to questions about the
suitability of the commercial configuration likely to be offered. The
team also will review the OEM's catalog and decide which options are
required/desired for each proposed type of aircraft. Demonstration
flights of candidate aircraft may be included as part of these
conferences. Such flights will give the team members the opportunity
to increase their knowledge of the candidate aircraft, as well as to
better understand configuration options.
In this section we discuss strategies and processes for the
following activities:
|
| Task 2: Acquisition | FY 1999 | FY 2000 | FY 2001 | FY 2002 | FY 2003 | Total |
|---|---|---|---|---|---|---|
| (15.50 FTE) Total | 147,000 | 45,535,000 | 184,000 | 88,000 | 0 | 45,954,000 |
| Aircraft Size Class | Altitude | Range and Endurance | Payload | Cabin Volume | Cost (Purchase and Operations) |
|---|---|---|---|---|---|
| Light | High | Moderate | Low | Low | Low |
| Mid-Sized | High | High | Moderate | Moderate | Moderate |
| Heavy | Moderate | High | Very High | Very High | High |
In addition to the attributes shown above, other factors will be highly important. For example, one critical factor is the ability of HIAPER to operate in fully loaded configuration from a variety of airports, including the existing RAF base at Jefferson County Airport (Jeffco). This requires examination of the candidate aircrafts' take-off performance, noise-generation characteristics, and maximum gross weight. Maximum gross weights for the light, mid- and heavy-size classes above are in the ranges of 20,000-40,000 lbs, 50,000-100,000 lbs, and 160,000-180,000 lbs, respectively. Because of runway strength limitations at Jeffco, it is unlikely that the latter class could operate there; acquiring any plane in this class would require that RAF either set up a separate operations base for HIAPER or move its entire base to another airport.
Two other examples of the many additional factors to be considered when narrowing down the list of candidate aircraft are design longevity and cabin loading flexibility. At least one of the available mid-sized business aircraft is designed for a minimum life of 20 years and 30,000 flight hours. NCAR routinely operates its research aircraft for over 20 years. At the anticipated usage rate for HIAPER, some 10,000-15,000 flight hours might be flown during that period. Cabin loading flexibility is important for HIAPER because of the diverse nature of typical research payloads. Thus an important attribute for HIAPER will be a wide range in the aircraft's forward-aft center-of-gravity limits.
Preliminary evaluation to date indicates that the most suitable candidates for HIAPER will come from the mid-sized business aircraft class. However, substantial additional interaction with industry will be necessary for the HIPT to develop a better understanding of the many detailed advantages and disadvantages of each candidate aircraft relative to the defined HIAPER requirements.
The selected contractor will be encouraged to establish its own
Integrated Product Team (IPT), consisting of the personnel from each
functional organization that will be involved in the delivery of the
aircraft. The selected contractor's IPT, with HIPT membership, will
work together to manage the effort defined by the contract. (The use
of such working partnerships is a distinctive feature of modern
commercial aircraft contracting practice.) The contract, in concert
with the selected contractor's existing company processes, will be
used to measure program performance and assess progress. The
contractor's processes and production tracking procedures will be used
to give insight into program performance and risk management. The
selected contractor will be encouraged to use, to the extent
practical, electronic media for all program management communications.
The IPT process will be used to review program requirements, schedule,
current status, technical manuals, logistics support, and design.
Weekly conference calls will be held with all IPT members, to conduct
business that does not require on-site presence. Management data and
formats used by the contractor will be provided to UCAR.
Configuration management will be conducted using standard commercial
practices such that the design data for the modified aircraft is
traceable to the final (as-built) configuration. The selected
contractor will provide all applicable optional Service Bulletins
(from airframe manufacturers, vendors, etc.) not automatically
incorporated into the aircraft for UCAR to determine desirability for
incorporation. A method of maintaining the currency of contractual
specifications will also be provided. UCAR and NCAR concurrence on
the detailed design of the aircraft modification will be ensured
through the IPT process.
Adequate price competition is anticipated, and UCAR will ensure open
competition. Initial industry analysis indicates an acceptable number
of interested and qualified sources, consisting of OEMs and completion
facilities that can meet HIAPER requirements.
A single Firm-Fixed-Price contract will be issued for the purchase of
the aircraft and associated contractor modification, training, data,
and ten years of Contractor Logistics Support (includes spare parts
and maintenance). The contract will provide for the purchase and
modification of the HIAPER aircraft as stated in the Statement of Work
section of the contract. As part of the acquisition planning process,
industry input will be sought to ensure the logistics support concept
can be met. The contract will contain the appropriate contractual
language to ensure contractor performance throughout the life of the
contract.
Vendor involvement throughout the pre-award process will be actively
sought through Request for Information (RFI) letters and industry
conferences. RFIs will be issued to garner industry comments and
inputs on the HIAPER requirements and contracting strategy. These
will help determine if all requirements can be met through commercial
sources and products. The RFIs will assist UCAR in gaining a thorough
understanding of commercial business practices. In addition, draft
RFPs will be issued, when appropriate, to facilitate industry review
and technical input to the final RFP. The draft RFP process will
streamline the acquisition procedure by allowing offerors to gain an
understanding of the RFP prior to its formal issuance, thus shortening
the time needed for proposal preparation. As a result of early and
continuous industry involvement in the acquisition process, the
proposals submitted will have a much greater probability of meeting
requirements and allowing UCAR to make an expeditious award, within
budget and schedule.
The contract will provide limited data rights to UCAR for all special
data on the basic aircraft and its modifications developed under this
effort that would be useful for operations, maintenance, and future
modifications to the aircraft. The contract will also provide access
to basic aircraft engineering data. Data furnished to other UCAR
contractors will be subject to the same limitations and will not be
used for reprocurement actions.
FAR Part 15.3, "Source Selection" will be used for guidance and a tool
when the UCAR Contracts Office deems such use appropriate. FAR 15.3
prescribes policies and procedures for selection of a source in a
competitive negotiated acquisition. The procedures outlined in the
FAR are designed to:
All members of the PET will be identified in the Proposal Evaluation
Plan. The technical evaluators and advisors will perform the
technical evaluation of the proposed HIAPER aircraft, modification,
and logistics support. The contracts and business representatives
will be responsible for the review and negotiation of the contract and
business approach. A training session will be conducted covering the
proposal evaluation and decision process prior to the release of the
RFP. The Proposal Evaluation Plan will describe in detail the overall
proposal evaluation process and the organization and membership of the
PET, including: a summary of the acquisition strategy; a description
of the evaluation factors and subfactors and their relative
importance; a description of the evaluation process, methodology, and
techniques to be used; and a schedule of significant milestones.
The proposal evaluation will be conducted in accordance with the
approved plan. The evaluation factors, subfactors, and decision
criteria will be issued in the solicitation and used as the basis for
UCAR's selection of a source to be recommended to the NOC for
approval.
The criteria will be identified as factors and subfactors. The
factors and subfactors considered in evaluating proposals will be
tailored to include only those factors that have an impact on the
source selection decision. The factors and subfactors that apply to
the HIAPER acquisition and their relative importance will be
determined by UCAR as a result of the acquisition strategy discussed
above. The technical evaluation and decision criteria will be
supplemented by price and past performance of the offeror.
All evaluation factors, subfactors, standards, and decision criteria
will be documented in the PEP and released with the RFP. In addition,
the plan will document the process for analyzing past performance.
The methodology to be used for price analysis, "Most Probable Total
Cost" (MPTC), will also be documented in the plan to show offerors how
program costs will be evaluated. The MPTC will allow UCAR to analyze
the acquisition and support costs, and to factor in the operational
costs that might be reasonably experienced. UCAR will use this
analysis as part of its recommendation to NSF, based on price and
other related factors. The approved PEP will identify the ranking of
price related to other factors. Due to the unique technical nature of
the HIAPER program, it is anticipated that technical capability could
outweigh price.
As an example, a simple MPTC analysis for the HIAPER program could
consist of calculating a total MPTC by adding up the dollar amounts
associated with the following five elements: aircraft acquisition
price; logistics support price (including spare parts and
maintenance); training costs; operations and deployment costs; and
delivery adjustment. A slightly more sophisticated analysis could
apply weighting factors to each of these elements.
As a component of the operations costs for the MPTC analysis, fuel
usage will be evaluated at appropriate cruise altitudes given specific
trip or mission profiles. The offeror would provide operational data
for the aircraft platform being proposed. ATD will produce deployment
cost estimates based on typical deployment scenarios.
A delivery adjustment could be factored into the MPTC to represent the
costs associated with any potential late HIAPER delivery. This amount
could be some measure of lost monthly "value" associated with the
scheduled initiation of community service by HIAPER. This portion of
the MPTC analysis would motivate offerors to meet the required need
date and importantly, would recognize in the price analysis the lost
value to UCAR and the user community for the selected contractor's
inability to meet the aircraft need date.
Because of steadily increasing governmental restrictions on the
operations of public aircraft, NCAR and UCAR believe it unwise to
attempt to operate the HIAPER aircraft in this category. These
restrictions cover several areas, including missions that may be
performed, crew that may be carried, maintenance required, training
and safety documentation required, and cost recovery allowed. For
example, if HIAPER were operated as a public aircraft, NCAR could not
accept compensation for flight time from any organization except a
federal government agency (FAA Advisory Circular 00-1.1, "Government
Aircraft Operations").
Non-certified aircraft must display a public aircraft document in lieu
of the airworthiness certificate. Public aircraft must be registered
in accordance with FAvR Part 47 and must display nationality and
registration marks in accordance with FAvR Part 45. Further, all
U.S.-registered aircraft engaged in international air navigation are
required to have a valid certificate of airworthiness (FAA Advisory
Circular 20-132, "Public Aircraft"). Further regulations on public
aircraft would be imposed if additional bills currently pending in
Congress (HR 1521 and HR1483) are enacted.
Accordingly, NCAR expects to operate HIAPER as an FAvR-Part 21
certified aircraft in either the standard or restricted categories, as
appropriate. This will require that all aircraft modifications as
well as supplemental aircraft equipment be FAA-certified through such
standard mechanisms as Supplemental Type Certificates and/or Form
337s. This is the way NCAR operated the King Air and Sabreliner. If
a compelling reason should develop in the future for operating HIAPER
either temporarily or indefinitely as a public use aircraft, this can
be authorized at that time by the Director, FAA Flight Standards
Service.
The major objective of FAA aircraft certification policy is to enhance
flight safety. A disadvantage of FAA-certified operation is that the
cost of the necessary certifications can be significant. This
additional cost can be largely offset by the aircraft's future
residual resale value, which will be dramatically enhanced if FAA
certifications are maintained. An example of this is the recent sale
of the NSF/NCAR King Air, which would have brought a much lower price
if it had not been currently FAA-certified.
Phase 1 - The Aircraft Characteristics Evaluation (ACE): This will be
part of the initial suitability evaluation and selection of the
candidate aircraft prior to, or during, proposal evaluation and source
selection. Each offeror will be required to execute an ACE
questionnaire, the results of which may be reflected in final contract
language. Each offeror will also be required to arrange an interview
with, and elicit cooperative participation from, one of their
private-sector domestic operators of like equipment. The responses
from the operator to the customer portion of the ACE questionnaire
will be incorporated into the final evaluation of the candidate
aircraft. This operator input will also provide a benchmark for use
in evaluating offeror statements, general industry information, and
other operational experience concerning the candidate aircraft. As
another feature of the ACE questionnaire, each offeror will be asked
to provide sample data points on the performance envelope of their
candidate aircraft.
The ACE activity will include a Pilot-Cockpit Evaluation, which will
be designed to help UCAR and NCAR fully understand the offeror's
product. Each offeror will be required to provide either an operating
candidate aircraft, a fully operational simulator of the aircraft, or
a reasonable engineering mock-up of the aircraft for a designated NCAR
crew to evaluate. The results of this evaluation will be incorporated
into the baseline understanding of the qualities and capabilities of
the offeror's candidate aircraft.
Phase 2 - The Acceptance Procedure: This phase will be conducted after
the contractor has completed all manufacturing and modifications, and
notifies UCAR that the completed aircraft is ready for customer
evaluation. The UCAR team that conducts this evaluation will use an
acceptance checklist as provided in a formal acceptance plan. The
aircraft must have a manufacturer's certificate of airworthiness prior
to customer acceptance. The acceptance evaluation will include both
ground inspection/tests and flight tests.
In the flight-test portion of the acceptance evaluation, the
contractor will be required to provide a minimum of four hours of
flight time for a selected NCAR crew to fly the aircraft to verify
certain aspects of the completion that can only be accomplished while
in flight. During this flight, the contractor will retain
pilot-in-command authority (for safety and liability reasons) and will
provide an instructor pilot or demonstration test pilot who has such
authority. All flaws in manufacturing or materials, exceptions to
specifications, or deviations from agreed-upon configuration, as
revealed in the acceptance evaluation, will be resolved to UCAR's
satisfaction prior to the successful completion of this step and
subsequent title transfer from the contractor to NSF.
5.2.2 Acquisition Strategy
5.2.2.1 Program Management Strategy
The primary management objectives are two-fold:
Figure 7 summarizes the aircraft acquisition tasks and their anticipated duration.

5.2.2.2 Contracting Strategy
The HIAPER contracting strategy will be in accordance with all
relevant UCAR Policies and Procedures, which are in compliance with
the current NSF - UCAR Cooperative Agreement and applicable Office of
Management and Budget (OMB) Circulars. The UCAR Contracts Office
will, when appropriate, use the acquisition streamlining initiatives
outlined in the Federal Acquisition Regulation (FAR) Part 12,
"Acquisition of Commercial Items." This will ensure that there is a
common baseline of understanding within industry and a framework for
contractual clauses and structure. FAR Part 12 provides a guideline
for acquisition of commercial items through a limited number of
contract clauses. Where appropriate and in compliance with UCAR
Policies and Procedures, FAR clauses may be used. Unique aspects of
the HIAPER program will be supported by either tailoring existing FAR
clauses or by the creation of HIAPER-specific clauses to meet program
requirements. Commercial terms and conditions will be used whenever
appropriate. Best business practices will be accomplished by early,
frequent, and open communication with industry to ensure that industry
can provide a business solution that best meets the unique
characteristics of the HIAPER program.5.2.2.3 Proposal Evaluation Plan (PEP)
The PEP will document the proposal evaluation and source selection
procedures and the evaluation and decision criteria. This plan will
be prepared in accordance with UCAR Policies and Procedures and will
be submitted to the NOC for approval.
For the purposes of the HIAPER acquisition, a subset of the HIPT,
perhaps with additional expertise, will constitute a Proposal
Evaluation Team (PET) consisting of technical evaluators, technical
advisors, contracts/business representatives, and appropriate members
of the NOC.5.2.2.4 Development of Evaluation and Decision Criteria
The HIAPER source selection will be a "Best-Value" competition
involving evaluation and comparison of price and other factors.
"Best-Value Procurement" is a contracting practice that reflects the
recognition that it is not always wise to make decisions based on
price alone, and that other evaluation criteria such as soundness of
approach, technical excellence, product quality, key personnel, past
performance, and other such relevant information are used to determine
which offeror has tendered the "Best Value" to the contracting
organization. Technical criteria may have more significance than
price. The strategy for the development of evaluation and decision
criteria will be the result of requirements definition, program
strategy, and industry input.5.2.2.5 Analysis of Most Probable Total Cost
The MPTC approach will allow UCAR to analyze acquisition and support
costs, and to factor in operational costs that might be reasonably
experienced. Operational costs will vary depending on the aircraft
platform proposed. The MPTC can also include adjustments based on
delivery performance, as described later in this section.5.2.3 Aircraft Certification and Acceptance
5.2.3.1 Federal Aviation Administration (FAA) Certification Requirements
The aircraft, as delivered from the selected contractor to UCAR, will
be certified in accordance with Federal Aviation Regulations (FAvR)
Part 25 (airworthiness standards), Part 34 (pollution), and Part 36
(noise). The aircraft will also carry a civil-registered "N" number
and a certificate of airworthiness (FAvR Part 21). All modifications,
including NCAR-provided research infrastructure, required to make the
aircraft "research ready" will also be FAA-certified, as discussed
below.5.2.3.2 Operations Category
NCAR's two current aircraft, the Electra and C-130, are operated as
"public aircraft." A public aircraft, as defined in the Federal
Aviation Act of 1958, is "an aircraft used exclusively in the service
of any government or of any political subdivision thereof including
the government of any State, Territory, or possession of the United
States, or the District of Columbia." The public aircraft category is
useful for operating military surplus aircraft, such as the C-130,
that have never carried FAA airworthiness certificates. Earlier NCAR
aircraft that were purchased new from commercial sources, such as the
King Air and Sabreliner, have been operated as FAA-certified aircraft.
5.2.3.3 Acceptance Procedure and Requirements
The HIAPER aircraft evaluation and acceptance activities will be
carried out in two phases:5.2.4 Community Oversight
Documents relevant to this task, including the HRD, the RFI, the RFP,
and the PEP, will all be available to the community for scrutiny and
comment through the HIAPER internet information system. The HAC and
the NOC will oversee all major components of this task through their
review and approval of these documents. In addition, status reports
on the progress of this task will be presented at the first and second
HIAPER community workshops and at appropriate OFAP and national
meetings.5.3 Task 3: Develop and Install NCAR-Provided Research Infrastructure
This section describes:
The estimated total costs for Task 3, in 1998 dollars, are given below: |
| Task 3: Infrastructure | FY 1999 | FY 2000 | FY 2001 | FY 2002 | FY 2003 | Total |
|---|---|---|---|---|---|---|
| (12.50 FTE) Total | 0 | 99,000 | 4,308,000 | 300,000 | 110,000 | 4,817,000 |
Airborne scientists must have tools to ensure quick understanding of
changing environmental conditions encountered during flight. To make
the best operational and scientific decisions possible, researchers
must have quick access to satellite, airborne, and ground-based data,
access to model outputs and guidance, and timely interactions with
other people on board and on the ground. They must have tools to
ascertain the functional status of observing systems and to assist in
changing flight objectives and operations to that status. They must
have access to real-time data that are fully calibrated and validated
through real-time quality control processes.
Access to high bandwidth satellite data communications and
satellite-based network connectivity are key to many of the concepts
we consider here. Current satellite data transmission available
through International Mobile Satellite Organization (Inmarsat)
aviation services achieves 2.4 Kbps, which is practical only for
limited data transfer needs. However, the global market for
satellite-based networking now drives rapid development of satellite
communication technology, and Inmarsat and other providers work toward
launch of next-generation satellites that will yield major increases
in bandwidth. Within three to six years, bandwidth available through
Inmarsat or other providers is projected to increase by a factor of
ten to 50.
The apparent dominance of Inmarsat technology for global data transfer
services today portends little with regard to future capabilities.
The Iridium constellation of low earth orbit satellites now coming
into service, or other systems, may yield more attractive alternatives
in the future. We will evaluate the capabilities and costs of all
alternatives as HIAPER development proceeds.5.3.1 Scientist Work Stations And Intercommunications
5.3.1.1 Objectives Served by Work Station and Communications Tools
Scientific and operational staff in the field will depend upon
advanced data handling and communications tools to accomplish tasks
critical to successful use of the aircraft and its observing systems.
These capabilities are essential for both onboard and ground-based
investigators. We also anticipate that because of NCAR and UCAR's
commitment to education, we have a unique opportunity to use evolving
communications technologies to provide interactive access to the
scientific process for students and faculty around the world.5.3.1.2 Functional Tools Required
With the above objectives in mind, we outline a brief model of
required functionality of proposed work station and communications
tools:
5.3.1.3 Technology Required
The model just described anticipates continued advances in computing,
networking and satellite communication technologies. Faster, smaller
processors, high-capacity disk drives and archive media, compact
high-resolution flat panel displays, and faster serial network
interfaces will each play an important role in the next-generation
network.
This section discusses:
|
| Task 4: Instrumentation | FY 1999 | FY 2000 | FY 2001 | FY 2002 | FY 2003 | Total |
|---|---|---|---|---|---|---|
| (17.50 FTE) Total | 0 | 5,700,000 | 534,000 | 4,806,000 | 556,000 | 11,596,000 |
Instrumenting an aircraft that operates at high altitude and high speed poses special challenges. To realize the full scientific potential of HIAPER, a substantial effort must be directed to instrumentation and particularly to exploitation of current advances in technology; instrumenting HIAPER for modern research will not amount simply to installation of existing sensors. Meeting this challenge will require an extensive collaboration among universities, NCAR and other scientific and technical groups.
Instrumentation requirements derive from the anticipated scientific needs (summarized in Section 2). Climate research requires measurements of radiative fluxes, radiation inside clouds, water vapor, convective structures and circulations, and measurements covering global scales with resolution comparable to that of climate models. Weather research needs dropsonde capability for targeted observations, measurements of precipitable water, characterization of hydrometeors and accurate characterization of air motions and thermodynamic structure. Tropospheric and stratospheric chemistry studies require measurements of the chemical species involved in photochemical cycles and deriving from terrestrial and oceanic sources. Atmospheric chemists also seek characterization of water vapor and chemically active trace gas profiles. Aerosol studies depend on measurements of particle size distributions and optical properties, both in-situ and remotely, and so require particle spectrometers, nephelometers, and active remote sensors such as backscatter lidar and instruments for measuring particle scattering phase functions. Satellite validation studies require spectral radiometers and measurement of the angular distribution of radiation as well as mapping of surface features at various wavelengths and resolutions.
For the most part, identified scientific needs match to existing
instrument development or to anticipated technologies. Over the
lifetime of HIAPER, however, new scientific questions and new
measurement technologies will evolve. We attempt to meet present
needs and leave flexibility for future research by first specifying a
primary set of advanced instruments, instruments that make fundamental
measurements and provide high quality data from every flight. We then
discuss a second set of special research instruments, constructed to
meet a set of design and infrastructural specifications, that can
easily mount on HIAPER and integrate with the HIAPER power and data
systems according to the scientific requirements of a specific flight.
This dual mode of instrumentation, with a primary and regular set of
fundamental capabilities and an interchangeable set of more
specialized research capabilities, should provide reliable and
flexible support to meet evolving scientific needs.
Humidity: Providing adequate coverage over a wide range of humidities
(ranging over partial pressures from above 50 mb to below 10-4 mb)
presents a difficult challenge. The high airspeed of the platform
introduces possible biases into some measurements, for example of
dew-point or vapor density, that depend on absolute humidity, so even
standard instruments will require special attention.
The primary in-situ humidity sensors currently in use are either too
old for continued support, too slow for flux measurements, or
incapable of making accurate measurements at low absolute
humidity. Tunable Diode Laser techniques currently being tested have
suitable detection limits and response time. Hybrid Lyman-alpha
detectors using fluorescence also have the necessary sensitivity.
Cryogenically-cooled dewpoint sensors may help achieve measurements at
low humidity. Technological developments now underway should provide
the basis for improved humidity measurements matched to HIAPER
capabilities.
Measurements of humidity must be made in ways that either fully
exclude or include the contribution for hydrometeors. Excluding
condensed-phase water will require special inlets. Measuring total
water content could be accomplished with complete evaporation of the
sampled water, perhaps as provided by counterflow virtual impactors.
Wind and Turbulence: HIAPER should measure both mean horizontal winds
and turbulent fluctuations in all three components of air velocity. A
likely minimum requirement for in-situ measurements of air motion on
HIAPER will be either a flush-mounted radome system or a conventional
boom-mounted gust probe, the choice to be based on structural
considerations and uses of the radome.
Although a high-speed aircraft provides advantages for obtaining
measurements quickly over considerable distances, increased speed
leads to increased dynamic errors in measuring the air velocity
components by pressure differences. A laser air velocity sensor
focused about 10 m ahead of the aircraft could resolve all three
air-velocity components while measuring in the undisturbed air at that
locale. Any HIAPER air motion system should incorporate a
state-of-the-art Inertial Reference System with high-rate sampling of
all three acceleration components and attitude angles. Essential
improvement in long-term accuracy can be achieved through
incorporation of an enhanced-accuracy GPS with three-axis capability
to measure attitude angle. Accurate high-rate measurements of aircraft
position, velocity and orientation are essential not only for air
motion measurements but also for many of the remote sensing
instruments planned for HIAPER. Higher frequency measurements of
small-scale turbulent structure by hot-film sensor technology may
represent another important capability for HIAPER.
Dropsondes and Other Sondes: HIAPER should have capability to deploy a
variety of sondes. Current users of the NCAR GPS dropsondes on NSF,
NOAA and USAF aircraft attest to the high importance of these sensors.
HIAPER will need automated launching capabilities for the dropsondes
and perhaps for other types of atmospheric and oceanic sondes as well.
Other Primary Measurement Capabilities: Pressure and geometric
altitude are key measurements for many applications. Measurements of
static pressure to a few tenths of a hPa are essential for calculating
true airspeed from dynamic (pitot) pressure and for measuring pressure
altitude; a radar altimeter with corresponding accuracy of a few
meters should be available. A C-band weather avoidance radar and
supporting data system may also represent an important HIAPER
capability.
The importance of these measurements, and the need for climatological
characterization, argue for their routine collection. In addition to
focused studies directed at cloud absorption anomalies or links
between cloud radiative properties and hydrometeor type, HIAPER will
also collect climatologically significant data during long transit
legs and during profiling of the vertical structure of the
atmosphere. With the simultaneous characterization of aerosol and
hydrometeor features, these radiation measurements will provide an
important data set for learning more about radiative fluxes in the
atmosphere. This aircraft also provides an important opportunity to
characterize actinic fluxes that determine photochemical
transformations. These measurements, which must be made in-situ, will
be valuable inputs to models of tropospheric chemistry.
A radiometric instrumentation suite should be capable of remotely
sensing the following: up-welling and down-welling radiative fluxes in
the ultraviolet, visible, and infrared portions of the electromagnetic
spectrum; total and diffuse radiative fluxes; and remote measurement
of surface temperature. RAF has used commercial radiometers to
measure radiative fluxes for a long time. Improved measurements can
now be obtained from radiometers custom built for use on aircraft. The
design and deployment of this instrumentation provides a good
opportunity for collaboration with university colleagues.
To acquire the climatological characteristics needed for studies of
atmospheric chemistry and atmospheric radiation, a case can be made
for including spectral radiometers and actinometers as standard
instrumentation. Recent advances make their inclusion as routine
instrumentation a possibility.
These routine observations, along with the primary aerosol and
radiation measurements, would provide a framework to interpret better
the more extensive measurements of NOx and HO necessary to understand
fundamental photochemical cycles of ozone and other materials in the
upper troposphere. These measurements will be made by special
research instruments described below.
Instruments are becoming available to characterize the asymmetry
parameter and optical extinction coefficient of hydrometeor
populations and the scattering phase function of individual
hydrometeors. A newly developed single-particle mass spectrometer has
revealed a surprising variety of components in aerosol particles, and
a new ice nucleus counter is providing airborne measurements.
Modifications of Hydrometeor Spectrometers: Primary measurements
should include the ability to characterize the complete aerosol and
hydrometeor size distribution, to measure the condensed-water content
of clouds and to partition this measurement between solid and liquid
phases.
Particle Measurement System probes are often used to measure
hydrometeor size distributions. These pose some problems for HIAPER,
mostly because they currently are based on outdated technology with
limited time response that compromises their use on a high-speed
aircraft. It will be important to upgrade these measurement
capabilities (perhaps by redesign of the electronics or by adoption of
new probes), and to reduce the drag associated with these probes.
There are some exciting new probes that will improve the achievable
resolution, but these are in relatively early stages of deployment and
need further testing and evaluation. Other groups, notably the Centre
National de Recherches en Metéorologie in France, have redesigned the
electronics for some of the probes; their designs should be considered
for HIAPER.
Aerosol Spectrometers: The challenge here is to measure a complete
aerosol size distribution while covering the wide range of
concentrations that will be encountered over the altitude range of the
aircraft. There are good candidate techniques and instruments, but
the current status of these is not well matched to the need for
routine unattended operation and compact installation. In addition,
the performance of many aerosol instruments degrades at low pressure,
so considerable development work is needed to provide suitable aerosol
instrumentation. This work can build on the current generation of
cloud nuclei counters, mobility analyzers, and optical particle
counters.
Many of the instruments required to characterize aerosols must be
housed within the aircraft. Historically, inlet losses have been the
primary source of sampling errors for these systems. HIAPER would
benefit from a community aerosol inlet and other collaborative efforts
to provide improved aerosol sampling.
Instruments that might contribute to these goals include:
A suite of cross-track scanning radiometers could provide mapping
capabilities at visible, infrared, and microwave wavelengths. These
measurements of the radiative properties of the ground or cloud below
the aircraft can be used to determine vegetation types, soil moisture,
sea, snow and ice characteristics, etc. Good candidate instruments
have been developed and deployed on research aircraft. Important
improvements in technology that could support smaller, faster and
otherwise improved versions of these instruments are now available.
Scanning radiometers can also support tomographic reconstruction of
atmospheric features, as has been demonstrated with microwave
radiometers. For such reconstruction, uniform illumination of the
feature of interest is essential, so the potential is best realized
with upward-scanning radiometers.
A second important role for HIAPER will be to deploy instruments that
measure a variety of stratospheric gases, such as a remote sensing
Fourier transform spectrometer. The high altitude and long range
capabilities of HIAPER are critical to successful deployment of such
devices; these measurements are important additions to in-situ process
studies and useful for intercomparisons with global satellite-borne
observations. It will also be valuable to be able to collect air
samples for laboratory detection of species that cannot be measured in
flight.
HIAPER should have external ports and hardpoints that can be used for
future instrumentation. It should provide a series of inlets suitable
for gas phase and aerosol sampling. The upcoming community
instrumentation workshop will provide an opportunity for thorough
discussion of these modification options. We discuss two candidate
modifications below.
A series of hardpoint windows, similar to those on the Electra, might
be installed on the belly and roof of HIAPER, along the plane's
centerline. These hardpoint windows could be used for mounting
individual sensors that sample the external airstream, or for
pass-throughs to belly and roof 'canoes', faired pods mounted to the
fuselage. These belly and roof canoes could support the installation
of up- and down-looking instrumentation on the aircraft, including air
inlets, in-situ sensors, and remote sensors. The hardpoint windows
would provide instrumentation access between the fuselage and canoe
interiors. With canoes removed, the aircraft will be able to attain
its original flight configuration. The canoe design should allow
modular instrument installation on structures the ATD shop can design
and fabricate. The height, diameter and shape of the canoes will be
such that remote sensors can scan from horizon to horizon from within
the canoes (with an appropriate window shielding the antenna from the
airstream). HIAPER's canoe structures might match similar features
planned for the NOAA G-IV, which would allow exchange of instruments
between the two aircraft.
The nose of HIAPER might support a cylindrical extension of the
fuselage in place of the standard radome. An alternate hemispherical
radome would mount on the front of the extension. The cylindrical
section could support remote sensing and in-situ sensing instruments.
The concept is similar to that implemented on the NSF/NCAR King Air
aircraft. It provides the ability to fly a wide variety of sensors
within the cylindrical section while using the radome with a
conventional weather avoidance radar.5.4.1 Challenges
Most measurements become more difficult during operation at high
speeds because of compression and dynamic heating of the airflow and
distortion of airflow trajectories around the aircraft. Sampling in
clouds becomes especially difficult because the evaporation of cloud
water can affect measurements such as temperature or humidity. Also,
hydrometeor trajectories around the aircraft depart to varying degrees
from airflow trajectories, leading to enhancement or depletion of
hydrometeor concentrations. Heating and distortion of airflow around
the aircraft may also affect remote sensing systems. High flight
stresses make instrument mounting more difficult; all exterior
mounting systems need to minimize interference with the aircraft's
aerodynamically clean profile. The altitude range of the aircraft
poses special requirements because of the correspondingly wide
concentration ranges of many properties. Humidity or particle
concentrations, for example, may vary by a factor of 100,000 or more
during a sounding. External instruments must also operate at very low
ambient pressure. These factors require careful attention when
planning and developing the primary and special instruments for
HIAPER.5.4.2 Objectives
We suggest a set of specific objectives to
guide HIAPER instrument developments:
5.4.3 Mechanisms for Community Participation
Developing an advanced suite of primary and special research
instruments that meet community research objectives will require
extensive collaboration. Collaborators include university scientists
and engineers, NCAR scientists and engineers, and scientific and
technical staff from national and international laboratories and/or
private industry. These collaborations may take several forms:
5.4.4 Primary Instruments
This discussion of primary instruments, those that will operate
routinely on every flight, focuses on likely requirements for HIAPER.
A broader community discussion of primary instrumentation will occur
in a community-wide workshop to be held in early 1999.
5.4.4.1 State Parameters and Other Primary Measurement Capabilities
Temperature: Some standard exposed sensors seem to work well at high
speeds as long as the aircraft remains out of cloud. Adequate
temperature measurements in cloud and away from the aircraft using
remote-sensing techniques present greater challenges. When exposed
sensors become wet, associated evaporative cooling causes an error
that becomes larger with increasing airspeed, leading to a serious
problem for in-cloud measurements. We anticipate assigning a high
priority to the development of new in-cloud temperature capabilities.
5.4.4.2 Primary Radiation Instruments
Recent trends in climate research have focused attention on the
importance of measuring contributions to the global radiation
budget. Uncertainty regarding how clouds influence radiation and how
that influence might respond to climate change is a major obstacle to
climate prediction. Similar uncertainty exists regarding the radiative
forcing from anthropogenic aerosols. HIAPER should play a major role
in the reduction of these uncertainties, so good measurements of
radiation are essential.5.4.4.3 Primary Chemistry Instruments
Standard measurements to be made from HIAPER include chemical tracers
of the exchange of air between the UT/LS, ozone and water vapor.
Instruments to measure gases such as CO, CO2 and CH4, which can be
relatively automatic and compact, should be deployed at every
opportunity to construct a climatology of the exchange of air in the
UT/LS. Coincident measurements of ozone and water vapor should be
made to establish the background of these critical gases as correlated
with the transport of air in the UT/LS.5.4.4.4 Primary Cloud Physics and Aerosol Instruments
Cloud physicists need to measure the optical properties of
hydrometeors and aerosols; total and partitioned-by-phase condensed
water content; cloud condensation and ice nuclei; aerosol size
distributions in and out of cloud; spectrally resolved radiative
fluxes in clouds; the composition and hygroscopic properties of
aerosol particles; and the chemical constituents in cloud water or
ice. Aerosol physicists need to measure optical properties; chemical
composition; and nucleating ability of aerosol particles. None of
these measurements are now routinely available on NCAR aircraft, but
all are feasible for installation on HIAPER.5.4.5 Special Instrumentation
This section provides some examples of special use instrumentation
that may be suited to HIAPER. The instruments surveyed here are
intended as examples of capabilities that may be possible with
suitable development effort. Priorities for these instruments need to
be determined by a process involving the full user community,
including the workshops mentioned earlier. Ideally, instruments
discussed in this section should fit the 'plug-and-play' model for
specialized HIAPER research instruments.5.4.5.1 Remote Sensors
In the extreme, remote sensing instrumentation on HIAPER might provide
3-D fields of winds, temperature, humidity, and hydrometeor type and
concentration in regions near the aircraft. Scanning radiometers
might provide cross-track mapping of surface emissions at several
wavelengths. Future remote sensing techniques might detect a variety
of chemical species.
5.4.5.2 Special Radiation Instruments
The need to resolve the spectral and angular distribution of radiative
fluxes at flight level will require specialized radiation measurements
on HIAPER. Instruments will be needed that measure the wavelength
dependence of radiative fluxes and that scan with high angular
resolution. There will also be a need for multichannel radiometers
that operate in cloud and that provide full 360( scanning to document
the full angular distribution of radiation in clouds. Extensive
measurements of actinic flux, valid in and out of cloud, will also be
needed to support studies of photochemistry.5.4.5.3 Chemistry Instruments
HIAPER's payload should include special research instruments to
measure in-situ concentrations of NOx, NOy and HOx, together with
primary instruments to measure the set of trace constituents listed in
Section 2. The selection and development of these and other
specialized instruments will depend upon significant community
involvement and provide good opportunities for collaboration with
universities and other research institutions with expertise in
measurement of critical chemical constituents.5.4.6 Structural Modifications to Meet Instrumentation Needs
It is not possible to specify the full range of instruments a platform
like HIAPER will need to carry over its lifetime. HIAPER should
therefore have flexible configuration and infrastructure that can
support unanticipated instrumentation. Airframe modifications and
aircraft flight capabilities represent two major design aspects that
will determine the utility of the aircraft over its projected 25-30
year lifetime. The modifications described here would support the
kinds of instrumentation described in this document, and provide good
flexibility for the installation of new sensors as they are developed.
This section presents UCAR/NCAR's plan for preparing for
operations and covers:
|
| Task 5: Prep. for Operations | FY 1999 | FY 2000 | FY 2001 | FY 2002 | FY 2003 | Total |
|---|---|---|---|---|---|---|
| (13.25 FTE) Total | 0 | 0 | 118,000 | 244,000 | 2,520,000 | 2,882,000 |
5.5.1 Staff Training
The successful contractor will provide to RAF staff initial and
follow-on training for the period of time specified in the system
support portions of the contract. UCAR will specify the types and
levels of training needed for each person to attain full operations
and maintenance capabilities. To the maximum extent possible, the
formal "trained to" standards usual and customary in operations of
this nature will be followed. Training levels for operations personnel
will aim at formal licenses where applicable. All training will be
accomplished by fully qualified commercial vendors who meet industry
standards for type, level and detail of training.5.5.2 Aircraft Maintenance Program
We anticipate a two-level maintenance program for HIAPER: flight line
and minor maintenance accomplished in-house and major extensive
maintenance accomplished by a support contractor. The support
contractor will be the OEM contractor or a third party designated by
the contractor, as specified in the successful aircraft proposal.
5.5.3 Technical Manuals
Technical manuals for all systems and functions will be prepared by
the contractor to the industry standard level of detail, with
tailoring as needed to meet HIAPER requirements. Follow-on technical
manual support will also be required by the contract. Changes,
updates, and all other usual and customary support provided to the
general customer base of the contractor will be provided to UCAR.
Specific technical manual issues will be worked out through a special
IPT for Technical Manuals comprised of members of UCAR and CAIPT
acquisition staff, NCAR operations and maintenance staff and
contractor personnel.

UCAR, under NSF sponsorship since 1960, has managed NCAR on behalf of the university community, in a unique partnership with that community that serves all parties with excellence. UCAR's mission was confirmed by the UCAR Member Representatives through the publication in 1991 of UCAR's Strategic Plan4. Subsequently an assessment of progress toward that plan5 was published. UCAR'S mission is:
Of the six goals identified by UCAR the two highest are:
"UCAR and NCAR are unique among scientific organizations in the United States in achieving leadership in scientific research and service to a broad and disparate community."
"NCAR's responsiveness to the needs of the broader atmospheric community is particularly noteworthy. This is the result of its close working relationship with UCAR, which manages and operates NCAR on behalf of 62 North American universities with atmospheric related programs."
The NCAR Director's Office provides administrative support in research
planning and budgeting to all NCAR divisions, and each division, in
turn, has skilled administrators and managers to handle business
matters.
During the past 38 years, UCAR and NCAR have initiated, planned, and
successfully conducted many major procurements on behalf of the
community and sponsors. A few examples are:
The governing principles for UCAR acquisitions are the UCAR Contracts
Policies and Procedures, which ensure compliance with the current
UCAR-NSF Cooperative Agreement, other federal agency cooperative
agreements, prime contracts, grants, subawards and other contractual
documents used to transfer funding. Specific terms and conditions
which have flow-down applicability, such as FARs, specific OMB
Circulars, NASA FAR supplements and the Uniform Commercial Code, are
addressed in the UCAR Contracts Policies and Procedures. The UCAR
Contracts Office is charged with negotiating and administering the
provisions that are included in these various funding agreements and
with ensuring proper flow-down to subcontracts.
NCAR's current generation airborne data system, ADS-II, and associated
software provides advanced data handling on the C-130 and Electra.
The NOAA G-IV aircraft also relies on an ADS-II system built and
adapted by NCAR to NOAA's specialized needs. As outlined in Section
5.3, the ADS-II system uses modular design and leading
technologies. This system allows for easy integration of the diverse
user supplied instrumentation that NCAR incorporates into aircraft
payloads. NCAR's WINDS software system provides flexible real-time
display of data.
NCAR maintains proven capability for worldwide deployment, built
through experience on six continents in all seasons at both populated
and remote locations. Flight crews are highly experienced in all
aspects of international operations. Maintenance crews are fully
equipped and experienced in the completion of routine and nonroutine
maintenance in the field. Logistics staff is proficient in securing
the arrangements necessary to ensure proper access to ground services,
maintenance support, and medical support.6.1 Administrative Support Capabilities
UCAR's administrative services include contracting, risk management,
accounting and financial reporting and human resources. Centralized
corporate-wide activities in these areas are carried out through the
UCAR Finance and Administration (F&A) group, which develops and
implements policies and procedures involving all business and human
resource management. These activities are monitored and overseen by
the UCAR Board of Trustees as well as by NSF. Additionally, regular
audits are conducted by Deloitte and Touche, as well as by the
Inspector General of NSF.
In all of these major projects, UCAR and NCAR have successfully
performed the administrative and business tasks necessary to satisfy
the increasingly more complex requirements for subcontracting,
acquisition, reporting, spending and record-keeping. The current
administrative systems in UCAR F&A are well suited for conducting the
HIAPER project, in concert with the university community and NSF.
6.1.1 Authority
Authority to bind UCAR resides in the President of UCAR as delegated
by the UCAR Trustees. The President may, in turn, delegate all or
part of this responsibility for preparation, execution and
administration of UCAR subawards and subcontracts. The President has
delegated this responsibility to the Contracts Office through the Vice
President for F&A. Purchase orders, subawards, or other arrangements
binding UCAR are issued only through the Contracts Office, except in
cases of emergency as determined by the Manager of Contracts or by
policy.6.1.2 Policy
It is the policy of UCAR to acquire all goods, services and research
from outside sources using open competition, to the maximum practical
extent consistent with the objectives and requirements of the NSF-UCAR
Cooperative Agreement.6.1.3 Source Selection
It is UCAR's policy to seek new qualified sources and to monitor the
performance of currently qualified vendors. Surveys of vendors'
facilities are conducted, when appropriate, to estimate the
performance capability of potential and/or actual suppliers. A survey
by questionnaire is sometimes used to gather information from
potential suppliers to evaluate their financial and productive
capabilities. A survey by a UCAR team through a visit to a vendor is
used, when appropriate, to evaluate the vendor's performance and
technical capabilities.6.2 NCAR Capabilities in Research Aviation
NCAR's success in research aviation derives from unique expertise and
from devotion to the needs of the diverse research community that we
serve. We challenge ourselves to repeat and extend our high level of
service with each new deployment.6.2.1 Research Aircraft Development and Modification
NCAR has developed and operated nine research aircraft for the NSF,
beginning with a pair of Beech Queen Airs in 1964. A sequence of
aircraft including the DeHavilland Buffalo, North American Sabreliner,
Schweitzer sailplane, and Beech King Air, matched with successive
generations of NCAR research infrastructure, logged thousands of
research flights around the world. Responding to need for larger
payloads, greater range and greater endurance than these aircraft
could provide, today's NSF/NCAR fleet consists of a Lockheed C-130 and
a Lockheed Electra. Both are heavy-lift turboprops that bear
extensive NCAR-developed airframe modifications and research
infrastructure.6.2.1.1 Lockheed C-130 Hercules
NSF acquired the C-130 via government surplus in FY 1993. An intense
NCAR effort transformed the aircraft from a special-purpose military
facility to a flexible, cutting-edge flying observatory. Now entering
its fifth year in service as a research platform, the C-130 carries
NCAR-developed airframe modifications and data/power-handling
infrastructure that enable extensive research payloads comprised of
NCAR and user-supplied instrumentation. Fuselage apertures of
different shapes and sizes accommodate remote sensors looking up, down
and scanning. The apertures accept optical windows or structural
plates that serve as mounting locations for a variety of gas or
aerosol inlets or other sensors. Large, interchangeable
instrumentation pods (two at any one time) carry optical particle
probes, active and passive remote sensors, and in-situ sensors under
each wing. The pods are especially useful for scanning remote sensors
that require wide-angle views with minimal blockage by the aircraft.
Wingtip pylons each carry two canister-mounted sensors, and structures
at fuselage top and bottom provide additional capacity for hemispheric
radiometers and other sensors.6.2.1.2 Lockheed L-188 Electra
In 1974 the Lockheed Electra became the first long-range, high
capacity aircraft in the NSF/NCAR fleet. Since that time NCAR has
developed aperture, boom, and pylon capabilities on the aircraft to
within the practical limits of the airframe. In 1991 the Electra
underwent its most radical modification: the replacement of its tail
and empennage structure with that of a Lockheed P-3 aircraft. The
greater structural strength of the P-3 tail is needed to accommodate
the tail-mounted antenna/radome assembly of NCAR's ELDORA airborne
Doppler radar.6.2.1.3 Strengths in Airframe Modification
The apertures, pods, pylons, booms, instrument fairings and fuselage
hard points that accommodate the extensive payloads available on the
C-130 and Electra are the product of specialized expertise in
structural analysis, engineering design, machining and sheet metal
fabrication within NCAR in close coordination with the aircraft
manufacturer. NCAR staff in aeronautical and mechanical engineering
have extensive experience in solving problems posed by aerodynamic and
inertial loading, vibration, aerodynamic flutter and other issues
specific to aircraft. NCAR design staff have decades of experience in
aviation work within NCAR and elsewhere in the industry.
State-of-the-art computer-aided engineering design tools are coupled
to advanced, numerically-controlled machine tools in NCAR's machine
center, allowing highly efficient design and fabrication of the most
complex structures and fittings. NCAR staff includes three highly
skilled specialists in the fabrication and repair of sheet metal
structures, essential in almost any airframe modification.
6.2.1.4 Strengths in Data System Design and Onboard Display
NCAR's expertise in computer engineering, signal processing, and
software development forms a very strong foundation for the
development of advanced airborne and ground-based systems for high
speed networking and the processing, recording, and display of data
products.6.2.2 Research Instrumentation Development and Support
NCAR's close collaborations with community observational scientists,
strong internal scientific staff and broad strengths in engineering
and fabrication yield a unique capability for the development and
support of cutting-edge instruments. NCAR developed and supported
systems are critical to observational studies in atmospheric
chemistry, radiation, cloud/aerosol physics, dynamical meteorology and
other areas. NCAR instrument systems span a breadth of technologies
covering exposed sensors, active and passive remote sensing and other
techniques. Early accomplishments include pioneering work in
techniques for measurement of air motions from aircraft. This work
subsequently resulted in development of the radome gust probe, a
reliable tool that has become the standard for research aircraft.
NCAR pioneered the development of dropwinsonde technology for sounding
the atmosphere from aircraft, and today leads efforts to incorporate
GPS technology in next generation sondes. NCAR GPS dropsonde systems
presently fly on both NOAA P-3s, the NOAA G-IV, the NASA DC-8, the
Canadian Atmospheric Environment Services' Convair, the German
Deutsche Luft- und Raumfahrt (DLR) Falcon and the ten C-130s of the
USAF Weather Reconnaissance (Hurricane Hunter) group. NCAR also
developed ELDORA, a state-of-the-art, multifrequency, rapid scan
airborne Doppler radar whose high resolution probing of tornadoes,
severe storms, frontal structures and boundary layer features is
leading to dramatic and fundamental insights into the structure of
small scale circulations in the troposphere. ELDORA also represents a
powerful example of ATD's design and engineering capabilities and of
international collaboration in instrument development.
NCAR is also well equipped to provide value-added modifications and
ongoing support to observational systems developed by other groups. We
refurbished the NASA developed Multichannel Cloud Radiometer (MCR) to
provide new capabilities for radiation measurements by the NSF
community. We will shortly complete lidar system modifications and a
scanning mechanism to adapt the Scanning Aerosol Backscatter Lidar
(SABL) for use in the difficult environment of a C-130 wing pod.
6.2.3 Flight Operations and Maintenance
NCAR flight crews meet or exceed the highest standards of the aviation
industry. Our pilots hold Airline Transport Pilot ratings and average
20 years of experience as pilot-in-command. Pilots and flight
engineers undergo frequent proficiency exercises and rigorous
simulator training each year. NCAR aircraft are maintained by an
experienced crew of FAA licensed mechanics working to a customized
maintenance plan developed by the manufacturer to meet the unique
needs of research aviation. Ongoing progressive inspection and
maintenance of airframes, controls and power systems is supplemented
by manufacturer prescribed major airframe inspections at four year
intervals on the C-130 and at five year intervals on the Electra.

Salaries and Benefits: All FTE employees' salaries, which include
costs for non-work time, are calculated at 85% before benefits and
overhead are applied. The benefit rate is calculated at the FY1999
rate proposed by UCAR to NSF of 49.3%; the overhead rate is calculated
as proposed at 45.7% during the project years. A chart calculating
the total estimated costs in 1998 dollars and with inflation is
included in Table 2 (Section 1.2). Overhead is calculated on modified
total direct costs, which excludes equipment, non-NCAR participant
supplement costs and subcontracts over $25,000.
Project labor costs were determined by identifying the type of
personnel and the percentage of staff time needed to complete each
task. The total estimated costs have been broken down by task and
fiscal year. Cost categories identified by NSF (Form 1030) were used
to show funding for each fiscal year during the life of the project.
Table 4 (Section 4.2) summarizes our staffing needs. This table
includes several FTEs for essential services that will be supported by
indirect rather than project funds.
Materials and Supplies: Along with hardware and software needs, we
include costs for materials and supplies for instrument design and
fabrication.
Contingency Funds: Because of the magnitude of the HIAPER project and
the uncertainty of schedules and out year costs, we include a modest
contingency of 2.7% to meet unanticipated acquisition and development
costs.
Equipment: We anticipate the need for some large equipment purchases
related to airframe modifications and instrumentation development.
These will include communication and network components, display
systems, major maintenance equipment, and instrument and remote
sensing components.
