VIIRS/JPSS1 Imagery Resolution Terrain Corrected Geolocation L1 6-Min Swath 375 m
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/viirs/vj103img.021
The VIIRS/JPSS1 Imagery Resolution Terrain Corrected Geolocation 6-Min L1 Swath 375m product, short-name VJ103IMG, contains the derived line- of-sight (LOS) vectors for each of the 375-m image-resolution or I-bands.
Description
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 VJ103IMG 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.
