JPSS-1 CrIS Level 1B Full Spectral Resolution V3 (SNDRJ1CrISL1B)

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/lvekytnsrnkp

The Cross-track Infrared Sounder (CrIS) Level 1B Full Spectral Resolution (FSR) data files contain radiance measurements along with ancillary spacecraft, instrument, and geolocation data of the CrIS instrument on the Joint Polar Satellite System-1 (JPSS-1) platform.

Description

This platform is also know as NOAA-20 (National Oceanic and Atmospheric Administration). The JPSS-1 mission with CrIS instrumentation is a follow-on to the Suomi National Polar-orbiting Partnership (SNPP) mission.

The CrIS instrumentation and data processing system is nearly identical to that of the SNPP satellite. The FSR files have 2,223 channels (*2211 apodized channels): 637 (*633) shortwave channels from 3.9 to 4.7 microns (2555 to 2150 cm-1), 869 (*865) midwave channels from 5.7 to 8.05 microns (1752.5 to 1242.5 cm-1), and 717 (*713)longwave channels from 9.1 to 15.41 microns (1096.25 to 648.75 cm-1). Each CrIS field-of-regard (FOR) contains 9 field-of-views (FOVs) arranged in a 3X3 array.

The Level 1B files contain 30 FORs in the cross track direction and 45 in the along track direction. Data products are constructed on six minute boundaries. CrIS is designed to be used with the ATMS (Advanced Technology Microwave Sounder) instrument.

Processing the data from both of these instruments together is referred to as CrIMSS (Cross-Track Infrared and Microwave Sounder Suite). Version 3 of this product contain improvements to the L1B calibration, geolocation, quality monitoring, and metadata. Additional information can be found in the NASA Cross Track Infrared Sounder (CrIS) Level 1B Product Users’ Guide.
