DescriptionThe Visible and Infrared Imager/Radiometer Suite (VIIRS) is a multi-disciplinary instrument that is being flown on the Joint Polar Satellite System (JPSS) series of spacecraft, including the Suomi National Polar-orbiting Partnership (S-NPP) that launched in October 2011. JPSS is a multi-platform, multi-agency program that consolidates the polar orbiting spacecraft of NASA and the National Oceanic and Atmospheric Administration (NOAA). S-NPP is the initial spacecraft in this series, and VIIRS is the successor to MODIS for Earth science data product generation. VIIRS has 22 spectral bands ranging from 412 nm to 12 µm. There are 16 moderate-resolution bands (750m at nadir), 5 image-resolution bands (375m), and one day-night band (DNB). The production of the VIIRS L2P SST data as part of the Group for High Resolution Sea Surface Temperature (GHRSST) is a joint collaboration between the NASA Jet Propulsion Laboratory (JPL), the NASA Ocean Biology Processing Group (OBPG), and the Rosenstiel School of Marine and Atmospheric Science (RSMAS). RSMAS is responsible for sea surface temperature algorithm development, error statistics and quality flagging, while the OBPG is NASA ground data system for production of daily VIIRS ocean products. JPL acquires VIIRS ocean granules from the OBPG in near realtime and reformats them to the GHRSST L2P netCDF specification with complete metadata. Data consists of global coverage at 0.75 km resolution with approximately 300+ five minute observation granules per day. The v2016.2 superceded the previous v2016.0 datasets which can be found at
