Suomi NPP CrIS Level 1B Normal Spectral Resolution V3 (SNPPCrISL1BNSR)

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/ozzpdwenp2nc

The Cross-track Infrared Sounder (CrIS) Level 1B Normal Spectral Resolution (NSR) data files contain radiance measurements along with ancillary spacecraft, instrument, and geolocation data of the CrIS instrument on the Suomi National Polar-orbiting Partnership Project (SNPP).

Description

In December 2014, the CrIS instrument on the SNPP satellite doubled the spectral resolution of shortwave infrared data being transmitted to the ground.

In November 2015, additional points were included at the ends of the longwave and shortwave interferograms to improve the quality of the calibration. Prior to November 2, 2015 the data are only available in Normal Spectral Resolution, after November 2, 2015 at 16:06 UTC, the data are available in both NSR and Full Spectral Resolution (FSR). The NSR files have 1,317 channels: 163 shortwave channels from 3.9 to 4.7 microns (2555 to 2150 cm-1), 437 midwave channels from 5.7 to 8.05 microns (1752.5 to 1242.5 cm-1), and 717 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.

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. 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). If you were redirected to this page from a DOI from an older version, the "Version History" tab will provide additional content including information about v3 of this product. Please contact the GES DISC user support if you need additional information.
