VIIRS Version 1 (Collection 1) snow and sea ice data sets will cease forward processing on June 17, 2024. The Version 1 data will remain available for download, but users are encouraged to transition to VIIRS Version 2. VIIRS Version 2 includes new snow, sea ice, and ice surface temperature data sets from both the NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite and the National Oceanic and Atmospheric Administration-20 (NOAA-20) satellite.
