  NSF HAIS Development Process

In August 2004, NCAR announced NSF's decisions regarding awards for the development of HIAPER instrumentation.

Principal investigator (PI) names as well as institutional affiliations, brief instrument descriptions, and an estimated development completion timeframe for each of the awards are given in the table below:

Instrument Award, Description, & Completion Timeframe
PI: Andy Heymsfield (UCAR/NCAR)
Estimated Completion: 2006

Small Ice Detector (SID) Probes - A particle light scattering instrument for measuring size distributions of particles in the 1 to 70 um size range and for discriminating between ice crystals and supercooled water droplets in mixed phase clouds.
PI: Rick Shetter (UCAR/NCAR)
Estimated Completion: 2006

HIAPER Atmospheric Radiation Package (HARP) - Spectrally resolved actinic flux measurements and spectroradiometric actinic flux and irradiance measurements.
PI: Teresa Campos (UCAR/NCAR)
Estimated Completion: 2006

Fast Ozone Instrument - Quantification of ozone mixing ratios at 5 Hz using the method of chemiluminescent reaction of ozone with nitric oxide.
PI: Eric Apel (UCAR/NCAR)
Estimated Completion: 2008

Trace Organic Gas Analyzer (TOGA) - In situ measurements of oxygenated volatile organic compounds (OVOCs), non-methane hydrocarbons (NMHCs), and halocarbons.
PI: Elliot Atlas (University of Miami)

Autonomous Airborne Ozone Photometer for the HIAPER Aircraft - Measurements of ozone mixing ratios versus time at a data rate of 1 Hz.
PI: Ed Eloranta (University of Wisconsin at Madison)
Estimated Completion: 2006-2007

High Spectral Resolution Lidar - Calibrated vertical cross sections of cloud and aerosol optical depth, backscatter cross section, and depolarization.
PI: James Garrison (Purdue University)
Estimated Completion: 2007

GPS Multistatic and Occultation Instrument for HIAPER - Measurements of water vapor distribution in the troposphere, ocean surface roughness, and soil moisture.
PI: Mark Zondlo (Southwest Sciences)
Estimated Completion: 2007

Vertical Cavity Surface Emitting Laser (VCSEL) Hygrometer - Measurements of water vapor concentration at a minimum frequency of 25 Hz over the entire range of the troposphere and lower stratosphere.
PI: Jose Jimenez (University of Colorado at Boulder)
Estimated Completion: 2008

Time of Flight Aerosol Mass Spectrometer (ToF-AMS) - Measurements of total PM1 mass concentrations for non-refractory (NR) species, size-resolved PM1 composition for NR species, single particle composition during selected portions of a flight, light scattering signal intensity for particles above ~250 nm correlated with mass spectral signal, and surrogate non-sphericity.
PI: M.J. Mahoney (JPL/Caltech)
Estimated Completion: 2007

Microwave Temperature Profiler (MTP) - Measurements of brightness temperature at three frequencies between 55.5 and 58.8 GHz to be used to retrieve a temperature profile about the aircraft flight altitude.
PI: Greg Huey (Georgia Tech.)
Estimated Completion: 2007

Chemical Ionization Mass Spectrometer (CIMS) - Measurements of nitric acid, pernitric acid, and sulfur dioxide in standard CIMS (negative ion) mode, and measurements of organics such as methanol, acetaldehyde, acetonitrile, and acetone in CIMS positive ion mode.
PI: Paul Lawson (SPEC Inc.)
Estimated Completion: 2007

2D-S (Stereo) and Cloud Particle Imager (CPI) Probe - CPI portion to provide 8-bit (gray level) images of particles, and 2D-S portion of probe to provide two different (orthogonal) views of particles.
