VIIRS/NPP Sea Ice Cover Daily L3 Global 375m EASE-Grid 2.0 Day V002

Published by NASA NSIDC DAAC | National Aeronautics and Space Administration | Metadata Last Checked: October 20, 2025 | Last Modified: 2025-03-31
This data set reports sea ice cover/extent derived from radiance data acquired by the Visible Infrared Imager Radiometer Suite (VIIRS). Following the approach used by MODIS, the algorithm converts VIIRS calibrated radiances into brightness temperature and computes sea ice cover using Normalized Difference Snow Index (NDSI). VIIRS flies on board the Suomi National Polar-orbiting Partnership (NPP) satellite.
