Delivery of new science data from the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite is expected to cease at 13:00 Universal Time (UTC) on November 2, 2026 (2026/306), NOAA's National Environmental Satellite, Data, and Information Service (NESDIS) announced. NASA archives and distributes data from Suomi NPP through Earthdata and multiple distributed data archive centers.
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.
Transition resources are now available for each instrument aboard Suomi NPP:
- VIIRS (Visible Infrared Imaging Radiometer Suite)
- CrIS (Cross-track Infrared Sounder)
- ATMS (Advanced Technology Microwave Sounder)
- OMPS (Ozone Mapping and Profiler Suite
- CERES (Clouds and the Earth's Radiant Energy System)
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 updated official NESDIS announcement.
