Known by its short-name, VJ146A1_NRT, this product contains 26 Science Data Sets (SDS) that include sensor radiance, zenith and azimuth angles (at-sensor, solar, and lunar), cloud-mask flags, time, shortwave IR radiance, brightness temperatures, VIIRS quality flags, moon phase angle, and moon illumination fraction. It also provides Quality Flag (QF) information specific to the cloud-mask, VIIRS moderate-resolution bands M10, M11, M12, M13, M15, M16, and DNB.", "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/C2781438623-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/Black-Marble_v2.0_UG_2024.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://nrt3.modaps.eosdis.nasa.gov/archive/allData/5200/VJ146A1_NRT/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2781438623-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"}, {"@type": "dcat:Distribution", "downloadURL": "https://www.earthdata.nasa.gov/data/projects/black-marble?tempAccess=PQ81CJc0-wU8_bo0eHoDDsTUtmUPtqal-lCTOvYiCmU", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/VIIRS/VJ146A1_NRT.002", "keyword": ["earth-science-visible-wavelengths-spectral-engineering-visible-radiance"], "license": "https://www.usa.gov/government-works", "modified": "2026-08-18", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/EOS/ESDIS/LANCE MODIS"}, "spatial": "[\"CARTESIAN\", [{\"NorthBoundingCoordinate\": 90, \"WestBoundingCoordinate\": -180, \"EastBoundingCoordinate\": 180, \"SouthBoundingCoordinate\": -90}]]", "temporal": "2023-10-10/2026-08-10", "theme": ["Earth Science"], "title": "VIIRS/JPSS1 Daily Gridded Day Night Band 15 arc-second Linear Lat Lon Grid Night NRT"}
