VIIRS/NPP Raw Radiances in Counts 6-Min L1A Swath - NRT

NRT

VIIRS/NPP Raw Radiances in Counts 6-Min L1A Swath - NRT product contains the unpacked, raw VIIRS science, calibration and engineering data; the extracted ephemeris and attitude data from the spacecraft diary packets; and the raw ADCS and bus-critical spacecraft telemetry data from those packets, with a few critical fields extracted. The shortname for this product is VNP01_NRT.

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.
