From March 20, 2024, the NOAA-20 satellite is executing the rephasing maneuver, which takes approximately 15 days. During this time, NOAA-20 will not meet its orbit requirements. Users should exercise caution when using NOAA-20 science data. Some missing granules and data degradation are expected. NASA's Physical Oceanography Distributed Active Archive Center (PO.DAAC) archives mainly the sea surface temperature (SST) datasets from the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard NOAA-20.
Delivery of new Suomi NPP data ceases on Nov. 2, 2026. Users should transition to alternative products.
