AirMOSS produces estimates of RZSM with data from a P-band synthetic aperture radar (SAR) flown on a NASA Gulfstream-III aircraft. The resulting soil moisture estimates capture the effects of gradients of soil, topography, and vegetation heterogeneity over an area of approximately 100km x 25km at each of the study sites. AirMOSS flight campaigns took place at least biannually from 2012 to 2015 at each site.", "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/C2274733329-ORNL_CLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://airmoss.ornl.gov", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://daac.ornl.gov/graphics/browse/sdat-tds/1418_1_fit.png", "format": "PNG", "mediaType": "image/png"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/protected/bundle/AirMOSS_L2_3_RZ_Soil_Moisture_1418.zip", "format": "ZIP", "mediaType": "application/zip"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/airmoss/campaign/AirMOSS_L2_3_RZ_Soil_Moisture/comp/AirMOSS_L2_3_RZ_Soil_Moisture.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/airmoss/campaign/AirMOSS_L2_3_RZ_Soil_Moisture/comp/L23RZSM-ATBD-V3.2.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.3334/ORNLDAAC/1418", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://opendap.earthdata.nasa.gov/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search?q=AirMOSS_L2_3_RZ_Soil_Moisture_1418&ac=true", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.3334/ORNLDAAC/1418", "keyword": ["earth-science-soils-land-surface-soil-moisture-water-content"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ORNL_DAAC"}, "spatial": "[[{\"WestBoundingCoordinate\":-123.283,\"NorthBoundingCoordinate\":54.1254,\"EastBoundingCoordinate\":-68.3196,\"SouthBoundingCoordinate\":9.87958}],\"CARTESIAN\"]", "temporal": "2012-09-18/2015-09-29", "theme": ["Earth Science"], "title": "AirMOSS: L2/3 Volumetric Soil Moisture Profiles Derived From Radar, 2012-2015"}
