Delivery of new science data products from the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite is still expected to cease at 13:00 Universal Time (UTC) on November 2, 2026 (2026/306), according to NOAA's National Environmental Satellite, Data, and Information Service (NESDIS). NASA archives and distributes data from Suomi NPP through Earthdata and multiple distributed data archive centers. The archive of historical data will remain available, but data users that rely on updated data should transition to alternative data sets as soon as possible.
Please note that the cessation date for Suomi NPP data is subject to change, and further updates will be provided as November 2 approaches.
In general, Suomi NPP data users can transition to NOAA-21 and NOAA-20 data products, which are accessible via NASA’s Earthdata Search and NOAA’s Product Distribution and Access (PDA) system. NOAA-21 and NOAA-20 are part of the Joint Polar Satellite System (JPSS) fleet and were designed to continue the Suomi NPP legacy by providing comparable science data products via similar instruments.
This includes data from the following instruments aboard Suomi NPP:
- Advanced Technology Microwave Sounder (ATMS)
- Clouds and the Earth's Radiant Energy System (CERES)
- Cross-track Infrared Sounder (CrIS)
- Ozone Mapping and Profiler Suite (OMPS)
- Visible Infrared Imaging Radiometer Suite (VIIRS)
Starting the transition now will allow users to adapt and implement algorithms and workflows before Suomi NPP data delivery ends. Additional information about complementary science data products will be shared as soon as they are available.
More details can be found in the official National Environmental Satellite, Data, and Information Service (NESDIS) announcement.
