VIIRS/NPP Day/Night Band Terrain Corrected Geolocation L1 6-Min Swath 750 m

The VIIRS/NPP Day/Night Band Terrain Corrected Geolocation 6-Min L1 Swath 750m product, short-name VNP03DNB includes the geolocation fields that are calculated for Visible-Infrared Imaging-Radiometer Suite (VIIRS) day-night band (DNB) Line of sight (LOS) for all orbits at the nominal resolution of 750 m. The locations and ancillary information correspond to the intersection of the centers of each Field of View (FOV) from 16 detectors in the DNB on the Earth's surface. The geolocation algorithm uses a number of inputs that include an Earth ellipsoid, geoid, and a digital terrain model along with the SNPP platform’s ephemeris and attitude data, and knowledge of the VIIRS sensor and satellite geometry. It provides geodetic coordinates (latitude and longitude), and related parameters for each VIIRS L1 pixel. The VNP03DNB product includes geodetic latitude, longitude, surface height above the geoid, solar zenith and azimuth angles, lunar zenith and azimuth angles, sensor zenith and azimuth angles, land/water mask, moon illumination fraction and phase angle, and quality flag for every pixel location.
