VIIRS/NPP Sea Ice Extent 6-Min L2 Swath 375m NRT
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/viirs/vnp29_nrt.002
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.
Description
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.
