AIRS/Aqua Near Real Time (NRT) Level 1B Infrared (IR) geolocated and calibrated radiances 281-channel BUFR-format subset for GMAO V005 (AIRIBRAD_NRT_GMAO) at GES DISC
Abstract:
The AIRS Infrared (IR) level 1B data set contains AIRS infrared calibrated and geolocated radiances in milliWatts/m^2/cm^-1/steradian. This data set is generated from AIRS level 1A digital numbers (DN), including 2378 infrared channels in the 3.74 to 15.4 micron region of the spectrum. A day's worth of AIRS data is divided into 240 scenes each of 6 minute duration. For the AIRS infrared measurements, an individual scene consists of 135 scanlines containing 90 cross-track footprints; thus there is a total of 135 x 90 = 12,150 footprints per AIRS IR scene.
(The Shortname for this product is AIRIBRAD_NRT_GMAO).

Description:
AIRS home page at NASA/JPL. General information on the AIRS instrument suite, algorithms, and other AIRS-related activities can be found. The Atmospheric Infrared Sounder (AIRS) instrument suite is designed to measure the Earth's atmospheric water vapor and temperature profiles on a global scale. It is comprised of a space-based hyperspectral infrared instrument (AIRS) and two multichannel microwave instruments, the Advanced Microwave Sounding Unit (AMSU-A) and the Humidity Sounder for Brazil (HSB).
