Data Description

    JPSS CrIS SDR Operational (CrIS_SDR) - 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.

    03/11/2022 - Please note, CLASS offers a reprocessed version (pre 1/30/2020) of this data using the improved algorithms. See the RPCRISSDR products search page for details.

    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 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.

    Beginning on August 11-14, 2014, CLASS started receiving the majority of JPSS data in gzip compressed format. The file names remained the same. Other than the file size being smaller, users do not need to make any changes to their software to use the data.

    On December 4, 2014, at approximately 1509 UTC, the CrIS Instrument transitioned to full spectrum mode. Full length Interferograms for the Mid-Wave and Short-Wave IR channels are now being collected. All Stored Mission Data products, SDRs, and higher level products are expected to remain unchanged.
