Data Description

    CRIS SDR Products (CRIS_SDR) - The Cross-track Infrared Sounder (CrIS) instrument onboard Suomi NPP provides atmospheric temperature and moisture observations for weather and climate applications. The CrIS sensor has three spectral bands: the long-wave infrared (LWIR) band (650-1095 cm-1), the mid-wave infrared (MWIR) band (1210-1750 cm-1), and the short-wave infrared (SWIR) band (2155-2550 cm-1). For each band, CrIS measures the infrared (IR) spectra from the Earth scene (ES) with a 3×3 detector array, corresponding to 9 field-of-views (FOVs) with a 14 km diameter at nadir or one field-of-regard (FOR). This data family includes calibrated radiance data (SCRIF or SCRIS) and geolocation (GCRSO) data. These Sensor Data Records (SDR) were generated from CrIS Raw Data Records (RDR) via the JPSS Interface Data Processing Segment (IDPS). CrIS SDR radiance products are assimilated into global numerical weather prediction (NWP) models, providing critical temperature and water vapor information for the improvement of weather forecasting. The CrIS sensor is also capable of sensing trace gas species (carbon dioxide, methane, carbon monoxide, ozone, among others) as well as critical climate variables such as surface temperature. CrIS SDR data obtained from the NOAA Comprehensive Large Array-Data Stewardship System (CLASS) are distributed as aggregated 8 minute files consisting of 15 granules in the Hierarchical Data Format v.5 (HDF5) with metadata attributes included.

Notes

    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 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.

    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.
