In other words, this file contains the calibrated M1 \u2013 M5, M7 and M13 dual gain band data from the nadir and near-nadir zones that would otherwise be discarded following post-calibration aggregation/Earth View Radiometric Calibration Unit.\n\nThe Level-1 and Level-2 swath products are generated from the processing of 6 minutes of VIIRS data acquired during theJPSS-2/NOAA-21 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. There are also 7 dual-gain VIIRS bands. The dual gain moderate resolution bands (M1 to M5, M7 and M13) have 6304 samples and the other moderate resolution bands have 3200.", "distribution": [{"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C3383725663-LANCEMODIS.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://ladsweb.modaps.eosdis.nasa.gov/api/v2/content/archives/Document%20Archive/Science%20Data%20Product%20Documentation/NASA_VIIRS_L1B_UG_August_2021.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://nrt3.modaps.eosdis.nasa.gov/archive/allData/5201/VJ202GDC_NRT/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C3383725663-LANCEMODIS", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://www.earthdata.nasa.gov/data/instruments/viirs/land-near-real-time-data", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/VIIRS/VJ202GDC_NRT.021", "keyword": ["earth-science-infrared-wavelengths-spectral-engineering-infrared-radiance", "earth-science-infrared-wavelengths-spectral-engineering-reflected-infrared", "earth-science-visible-wavelengths-spectral-engineering-visible-radiance"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-23", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/EOS/ESDIS/LANCE MODIS;NASA/GSFC/SED/ESD/BSL/VCST"}, "spatial": "[\"CARTESIAN\", [{\"NorthBoundingCoordinate\": 90, \"WestBoundingCoordinate\": -180, \"EastBoundingCoordinate\": 180, \"SouthBoundingCoordinate\": -90}]]", "theme": ["Earth Science"], "title": "VIIRS/JPSS2 Dual Gain IP NRT"}
