    • VIIRS/NPP Sea Ice Extent 6-Min L2 Swath 375m NRT

    Metadata Updated: September 18, 2025

    The Visible Infrared Imager Radiometer Suite (VIIRS) Sea Ice Extent 6-Min L2 Swath 375m is Near Real Time(NRT) (short name VNP29_NRT) data set reports the location of sea ice cover derived from radiance data acquired by VIIRS. Following the approach used by MODIS, the algorithm assumes that sea ice is snow covered and can be detected using the Normalized Difference Snow Index (NDSI). The VIIRS instrument flies on board the Suomi National Polar-orbiting Partnership (S-NPP) satellite.For more information, consult product users guide at:https://viirsland.gsfc.nasa.gov/PDF/VIIRS%20C2%20Sea%20Ice%20Cover%20Product%20User%20Guide%20v3.pdfAnd product Algorithm Theoretical Basis Document (ATBD):https://viirsland.gsfc.nasa.gov/PDF/VIIRS_SeaIceCover_ATBD_V2.pdf
