CAMEX3 NAST-I Radiance Products

The National Polar-orbiting Operational Environmental Satellite System (NPOESS) Aircraft Sounder Testbed- Interferometer (NAST-I) is a high resolution Michelson interferometer, developed at MIT Lincoln Laboratory, that derives its heritage from the non-scanning High resolution Interferometer Sounder (HIS) developed by researchers at the University of Wisconsin. The NAST-I instrument scans the earth from beneath the ER-2 with a nominal spatial resolution of approximately 2.5 km with a total of 13 earth views in the cross-track direction (the resultant swath width covers about 45 km). The unapodized spectral resolution of NAST-I is 0.25 1/cm within a 590-2810 1/cm (3.6-17 micron) spectral range. The instrument flies in the right superpod of NASA's high altitude ER-2 research aircraft. The infrared radiance measurements obtained from the NAST-I instrument provide detailed spectral characteristics of the atmosphere and land surface along with providing detailed atmospheric temperature and water vapor profiles derived from either physical or regression based retrieval algorithms.

(CAMEX-3) was based at Patrick Air Force Base , Florida from 6 August - 23 September, 1998, and successfully studied Hurricanes Bonnie, Danielle, Earl and Georges. CAMEX-3 collected data for research in tropical cyclone development, tracking, intensification, and landfalling impacts using NASA-funded aircraft and surface remote sensing instrumentation.

Flights were conducted in the Gulf of Mexico, the Caribbean and in the Western Atlantic Ocean.
