Last update: October 25, 2023
Data Set Short Name:
VJ129_NRT
Data Set Long Name:
VIIRS/JPSS1 Sea Ice Extent 6-Min L2 Swath 375m NRT
Platform:
Joint Polar-orbiting Satellite System-1 (JPSS-1; now NOAA-20)
Instrument:
Visible Infrared Imaging Radiometer Suite (VIIRS)
Product Description:
The VIIRS/JPSS1 Sea Ice Extent 6-Min L2 Swath 375m Near Real Time (NRT) data set with short-name VJ129_NRT 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 JPSS1 satellite.
