Instrument:
Visible Infrared Imaging Radiometer Suite (VIIRS)
Product Description:
The VIIRS/NPP Ice Surface Temperature 6-Min L2 Swath 750m Near Real Time (NRT) data set, short-name VNP30_NRT reports sea ice surface temperature (IST) derived from radiance data acquired by the Visible Infrared Imager Radiometer Suite (VIIRS) on board the Suomi National Polar-orbiting Partnership (NPP) satellite. Following the approach used by MODIS, the algorithm converts VIIRS calibrated radiances into brightness temperature and computes IST using a split-window technique.
