VIIRS/JPSS1 Day/Night Band Resolution Terrain Corrected Geolocation 6 Min L1 Swath 750m NRT

Metadata Updated: December 6, 2023

The VIIRS/VJ1 Day/Night Band Resolution Terrain Corrected Geolocation 6-Min L1 Swath 750m Near Real Time (NRT) product, short-name VJ103DNB_NRT includes the geolocation fields that are calculated for 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. A digital terrain model is used to model the Earth's surface. The main inputs are the spacecraft attitude and orbit ephemeris data, the instrument telemetry and the digital elevation model. The geolocation fields contained within the VNP03DNB Geolocation files include geodetic latitude, longitude, surface height above the geoid, solar and lunar zenith and azimuth angles, lunar phase angle and illumination fraction, satellite zenith and azimuth angles, and a land/water mask for each 750m sample. Additional information is included in the header to enable the calculation of the approximate location of the center of the detectors for any of the VIIRS bands. This product is used as input by subsequent VIIRS day/night band products, particularly those produced by the Land team.
