The view angle effects are removed from the directional reflectances, resulting in a stable and consistent NBAR product. Data are temporally weighted to the ninth day which is reflected in the Julian date in the file name.\n\nUsers are urged to use the band specific quality flags to isolate the highest quality full inversion results for their own science applications as described in the [User Guide](https://www.umb.edu/spectralmass/modis-user-guide-v006-and-v0061/mcd43a4-nbar-product/).\n\nThe MCD43A4 provides NBAR and simplified mandatory quality layers for MODIS bands 1 through 7. Essential quality information provided in the corresponding [MCD43A2](https://doi.org/10.5067/MODIS/MCD43A2.061) data file should be consulted when using this product.\n\nKnown Issues\n\n* For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=MODIS&sat=TerraAqua&as=61).", "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/C2218719731-LPCLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://appeears.earthdatacloud.nasa.gov/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.lpdaac.earthdatacloud.nasa.gov/lp-prod-public/MCD43A4.061/MCD43A4.A2024195.h25v04.061.2024204033747/BROWSE.MCD43A4.A2024195.h25v04.061.2024203234551.1.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.5067/MODIS/MCD43A4.061", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ladsweb.modaps.eosdis.nasa.gov/filespec/MODIS/61/MCD43A4", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://landweb.modaps.eosdis.nasa.gov", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://lpdaac.usgs.gov/documents/97/MCD43_ATBD.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://modis-land.gsfc.nasa.gov/MODLAND_val.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://modis-land.gsfc.nasa.gov/ValStatus.php?ProductID=MCD43A4", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2218719731-LPCLOUD", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://worldview.earthdata.nasa.gov/images/layers/previews/geographic/MODIS_Combined_L3_Nadir-BRDF_Daily.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://www.earthdata.nasa.gov/centers/lp-daac", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://www.umb.edu/spectralmass/modis-user-guide-v006-and-v0061/mcd43a4-nbar-product/", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/MODIS/MCD43A4.061", "keyword": ["earth-science-surface-radiative-properties-land-surface-anisotropy", "earth-science-surface-radiative-properties-land-surface-reflectance"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-22", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "LP DAAC;NASA/GSFC/SED/ESD/TISL/MODAPS;UMASS-B/SFE"}, "spatial": "[\"CARTESIAN\", [{\"NorthBoundingCoordinate\": 90, \"WestBoundingCoordinate\": -180, \"EastBoundingCoordinate\": 180, \"SouthBoundingCoordinate\": -90}]]", "temporal": "2000-02-16/2026-06-15", "theme": ["Earth Science"], "title": "MODIS/Terra+Aqua BRDF/Albedo Nadir BRDF-Adjusted Ref Daily L3 Global - 500m V061"}
