VJ103MOD - VIIRS/JPSS1 Moderate Resolution Terrain-Corrected Geolocation 6-Min L1 Swath 750m
VJ103MOD represents the short-name for the Joint Polar-orbiting Satellite System-1 (JPSS- 1/NOAA20) platform-based NASA VIIRS L1 terrain-corrected geolocation product, and contains the derived line-of-sight (LOS) vectors for each of the 750-m moderate-resolution, or M-bands. 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 produces geodetic coordinates (latitude and longitude), and related parameters for each VIIRS L1 pixel. The VJ103MOD product includes geodetic latitude, longitude, surface height above the geoid, solar zenith and azimuth angles, sensor zenith and azimuth angles, land/water mask, and quality flag for every pixel location. VJ103MOD provides a fundamental input to derive a number of VIIRS M-band higher-level products.
