Using a time-series of Landsat data, the three disturbance types were identified by abrupt changes in Tasseled Cap (dTC) indices of brightness, greenness, and wetness. Disturbances were detected by a Continuous Change Detection and Classification (CCDC) harmonic regression model applied to the time series. The dTC indices and disturbance results are provided.", "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/C2226005584-ORNL_CLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://above.nasa.gov", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://daac.ornl.gov/ABOVE/guides/ABoVE_ForestDisturbance_Agents_Fig1.png", "format": "PNG", "mediaType": "image/png"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/above/ABoVE_ForestDisturbance_Agents/comp/ABoVE_ForestDisturbance_Agents.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/above/ABoVE_ForestDisturbance_Agents/comp/Accuracy_results.csv", "format": "CSV", "mediaType": "text/csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.3334/ORNLDAAC/1924", "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/granules?p=C2226005584-ORNL_CLOUD", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.3334/ORNLDAAC/1924", "keyword": ["earth-science-ecological-dynamics-biosphere-fire-ecology", "earth-science-ecosystems-biosphere-terrestrial-ecosystems", "earth-science-land-use-land-cover-land-surface-land-use-land-cover-classification", "earth-science-vegetation-biosphere-vegetation-cover"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-23", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ORNL_DAAC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -169.96, \"NorthBoundingCoordinate\": 75.6853, \"EastBoundingCoordinate\": -98.974, \"SouthBoundingCoordinate\": 50.259}]]", "temporal": "1985-01-01/2012-12-31", "theme": ["Earth Science"], "title": "ABoVE: Landsat-derived Annual Disturbance Agents Across ABoVE Core Domain, 1987-2012"}
