VIIRS/NPP Imagery Resolution 6-Min L1B Swath SDR 375m NRT
Entry ID: VNP02IMG_NRT_1

[Get Data]


The VIIRS Level 1 and Level 2 swath products are generated from the processing of 6 minutes of VIIRS data acquired during the S-NPP satellite overpass. The VIIRS sensor has 5 high-resolution imagery channels (I-bands) that have 32 detectors (32 rows of pixels per scan), with twice the resolution of the M-bands and the DNB, that span the wavelengths from 0.640 µm to 11.45 µm. The ...

The spatial resolution of the instrument at viewing nadir is approximately 750 m for the Moderate-resolution and Day/Night Bands, and 375m for the Imagery bands.

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.
