S-NPP Product Descriptions: VNP29_NRT

Last update: September 10, 2018

Data Set Short Name:
VNP29_NRT

Data Set Long Name:
VIIRS/NPP Sea Ice Cover 6-Min L2 Swath 375m

Platform:
Suomi National Polar-orbiting Partnership (S-NPP)

Instrument:
Visible Infrared Imaging Radiometer Suite (VIIRS)

Product Description:
This data set reports the location of sea ice cover derived from radiance data acquired by the Visible Infrared Imager Radiometer Suite (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. The VIIRS instrument flies on board the Suomi National Polar-orbiting Partnership (S-NPP) satellite.
