Known by its short-name, VNP46A1_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", "downloadURL": "https://doi.org/10.5067/VIIRS/VNP46A1_NRT.001", "format": "HTML", "mediaType": "application/octet-stream", "title": "Data Information (HTML)"}, {"@type": "dcat:Distribution", "downloadURL": "https://nrt3.modaps.eosdis.nasa.gov/allData/5200/VNP46A1_NRT/", "format": "BIN", "mediaType": "application/octet-stream", "title": "Data Information (Unknown Format)"}], "identifier": "10.5067/VIIRS/VNP46A1_NRT.002", "keyword": ["earth-science-visible-wavelengths-spectral-engineering-visible-radiance"], "landingPage": "https://doi.org/10.5067/VIIRS/VNP46A1_NRT.001", "modified": "2026-02-10", "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": "2023-10-10/2023-10-10", "theme": ["Earth Science"], "title": "VIIRS/NPP Daily Gridded Day Night Band 500m Linear Lat.
