Abstract

The Crosstrack Infrared Sounder (CrIS) is a Michelson type Fourier Transform Spectrometer flying on-board the SUOMI NPP satellite that was launched into orbit on October 28th 2011. CrIS measures the Top of Atmosphere (TOA) infrared radiance. Calibration and validation activities at NOAA-STAR includes: 1) The double difference of CrIS field of view (FOV) intercomparison using the Community Radiative Transform Model (CRTM) where the FOV are consistent to 0.05K or better, 2) Simultaneous nadir overpass (SNO) radiance comparison of CrIS with IASI with 0.2K agreement over the window channels,3) Top of atmosphere radiance comparison of the measured with the CRTM with an agreement of 0.4K or better over the window channels, 4) Double difference of CrIS vs IASI with an agreement of 0.3K over the window channels., 5) Long term monitoring and trending of 55 parameters, 6) Geolocation assessment using VIIRS where CrIS now has an estimated accuracy of 1 Km. Calibration and validation of the CrIS SDR is essential because its radiance product is assimilated by the NWP algorithm leading to weather forecasting.
