All SNPP VIIRS forward processing has been temporarily suspended due to a GPS anomaly issue that began at 231Z November 2, 2024. All production of SNPP VIIRS land data products are suspended and until further notice users are advised not to use any SNPP VIIRS data products produced since 215Z on November 2, 2024. The NASA NSIDC DAAC will post updates as they become available.
