  • Attention JPSS Data Users! (updated on 10/19/2023):

    Now available! The reprocessed Sensor Data Records (SDR) for all instruments flown on S-NPP and reprocessed Temperature Data Records (TDR) for the ATMS instrument flown on S-NPP is now accessible via the CLASS web ordering system. The reprocessed data is located under their own data families listed on the drop down product menu. The date range which covers the reprocessing period for each instrument is:

    • ATMS SDR/TDR (2011-11-08 - 2019-10-15) - The complete record is available under RPATMSSDR and RPATMSTDR
    • CrIS SDR (2012-02-20 - 2020-01-29) - The complete record is available under RPCRISSDR
    • OMPS SDR (2012-01-30 - 2020-05-30) - The complete record is available under RPOMPSSDR
    • VIIRS SDR (2012-01-02 - 2020-04-30) - The complete record is available under RPVIIRSSDR

    The operational data received after the reprocessed date ranges uses the latest version of the reprocessing algorithm.

  • Attention JPSS Users! (10/13/2023):

    • Please note that in Spring of 2024 (TBD) all operational VIIRS Imagery Ellipsoid geolocation will be discontinued, except for the S-NPP (TBC) Ellipsoid geolocation for VIIRS M-Band imagery.
    • The VIIRS SDR data going forward will be automatically packaged with Terrain Corrected Geolocation, while prior imagery data will be associated with Ellipsoid geolocation.

  • Attention JPSS Users! (Updated 10/10/2023):

    Please note that data products from the NOAA-20 satellite should not be considered of operational maturity due to an anomaly over the weekend. The specific time periods that the data should not be considered operational is detailed below:

    • CERES: 09/29/2023 19:00 UTC to 10/02/2023 17:00 UTC
    • CrIS: 09/29/2023 19:00 UTC to 10/04/2023 00:00 UTC
    • OMPS: 09/29/2023 19:00 UTC to 10/06/2023 19:00 UTC
    • ATMS: 09/29/2023 19:00 UTC to 10/01/2023 20:45 UTC
    • VIIRS: 09/29/2023 19:00 UTC to 10/01/2023 20:45 UTC

  • Attention JPSS Users! (6/30/2023):
    JPSS data was delayed due to a hardware issue. The delay was from 6/28/23 1445Z (10:45 AM) ET to 6/29/23 2000Z (4:00 PM ET). The data backlog is processing and should complete sometime 6/30/23.

  • Attention GOES Users! (4/20/2023):
    GOES-18 has been declared as the Operational GOES-West satellite since 1800 UTC, January 4, 2023 replacing GOES-17. See data and products under the GOES-R Series Families on the drop down list.
