Description

The 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 nm. There are 16 moderate-resolution
bands (750m at nadir), 5 image-resolution bands (375m), and one day-night band (DNB).
