Data Description

    JPSS CrIS RDR (CrIS_RDR)
    In conjunction with the Advanced Technology Microwave Sounder (ATMS) the Cross-track Infrared Sounder collects atmospheric data to permit the calculation of temperature and moisture profiles at high (~ daily) temporal resolution. The Cross-track Infrared Sounder (CrIS) provides improved measurements of the temperature and moisture profiles in the atmosphere. Forecasters use temperature and moisture sounding data in advanced numerical weather prediction models to improve both global and regional predictions of weather patterns, storm tracks, and precipitation.

Notes

(Posted 02/17/2026) The CrIS instrument on board the S-NPP satellite is at the end of its operational use as of 02/11/26. Engineers were unable to restore the instrument to operational state following the Scene Selection Module (SSM) anomaly that occurred on 12/23/2025. S-NPP is currently tertiary and operating beyond its design life.

(Posted 06/01/2018) Many products from NOAA-20 are now available through CLASS back to Beta Maturity. Please note that the start dates listed below for each datatype apply to SNPP files. The start dates for all products by maturity levels by satellite id are available on NOAA's STAR website at https://www.star.nesdis.noaa.gov/jpss/AlgorithmMaturity.php. Under each date there is a link to the full review of the product along with the latest readme on the last column. We encourage all users to assess product maturity before ordering and applying the data.
