NRT

The Near Real Time (NRT) VIIRS/JPSS1 Imagery Resolution Terrain Corrected Geolocation 6-Min L1 Swath 375m (VJ103IMG_NRT) product includes the geolocation fields that are calculated for each VIIRS imagery resolution band (I-band) Line of sight (LOS) for all orbits at the nominal resolution of 375 m. The locations and ancillary information correspond to the intersection of the centers of each Field of View (FOV) from 32 detectors in an ideal I-band 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 VNP03IMG_NRT Geolocation files include geodetic latitude, longitude, surface height above the geoid, solar zenith and azimuth angles, satellite zenith and azimuth angles, and a land/water mask for each 375m 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 a large number of subsequent VIIRS Imagery Resolution products, particularly those produced by the Land team.

Processing Level

Quality This is a near real-time (NRT) product that has undergone expedited processing to make it available within 3 hours of observation time to meet the needs of the NRT applications community. NRT data are subject to geolocation errors or reprocessing. Usually the geolocationalerrors are minimal (less than 100 meters), however, there are situations, particularly before and after spacecraft maneuvers and during space weather events, when the difference can increase up to several kilometers.
