Description

The Visible Infrared Imager Radiometer Suite (VIIRS) Ice Surface Temperature 6-Min L2 Swath 750m is Near Real Time(NRT) (short name VJ230_NRT) product provides surface temperatures retrieved at VIIRS moderate resolution for Arctic and Antarctic Sea Ice, for both day and night. Following the approach used by MODIS, the algorithm converts VIIRS calibrated radiances into brightness temperature and computes IST using a split-window technique. VIIRS flies on board the NOAA-21 - formerly the Joint Polar Satellite System-2 (JPSS-2) satellite.
