[Get Data]


The VNP03DNB_NRT,a Near Real Time (NRT) product, 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 ...

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.
Access Constraints No constraints but users need to be registered with the ESDIS User Registration system (https://urs.eosdis.nasa.gov/users/new) to download files via the FTP site.
