AB: The Atmospheric Infrared Sounder (AIRS) on the EOS Aqua Spacecraft was launched on May 4, 2002. AIRS acquires hyperspectral infrared radiances in the 3.7-15.4 um spectral region with spectral resolution of better than 1200. The AIRS was designed to measure small changes in the hydrological cycle and has demonstrated in-flight exceptional radiometric and spectral stability and accuracy. This accuracy is achieved in orbit by transferring the calibration from a Large Area Blackbody to the on-board blackbody (LABB). The LABB theoretical emissivity is in excess of 0.9999 and temperature uncertainty is less than 50 mK. The LABB emitted radiance is NIST traceable through thermistors located on the internal surfaces. The radiometric accuracy predictions for AIRS based on the On-Board Calibrator, LABB, and pre-flight measurements give an accuracy of 0.2K – 3 sigma. Spectral calibration is achieved through pre-flight testing and in-orbit observation of atmospheric lines.
