P 700 SUOMI NPP / JPSS CROSS-TRACK INFRARED SOUNDER ( CRIS ) : INTERCALIBRATION WITH AIRS , IASI , AND VIIRS

A key part of the Calibration/Validation efforts for the Cross-track Infrared Sounder (CrIS) (e.g. Tobin et al, 2012; Revercomb et al., 2013) is the intercalibration of CrIS with the Atmospheric Infrared Sounder (AIRS) on EOS Aqua and with the Infrared Atmospheric Interferometer Sounder (IASI) on METOP-A. The spectral and radiometric accuracy goals of CrIS are very strict, and these in-orbit comparisons provide one way to assess the performance of CrIS at the order 0.1K brightness temperature level.
