The presence of ice was determined from 237,556 manually and AI-derived terminus positions acquired by satellite optical and radar observations. Months with no observations have been gap-filled using past and future observations of terminus positions and advance rates constrained by the average flow speed of the glacier.\n\nAnimations are also available for 206 catchments that show how the ice front positions have changed over the course of the time series and can be used as a quality control check.", "distribution": [{"@type": "dcat:Distribution", "description": "Includes a user's guide, supplemental documents like ATBDs and academic papers, How Tos, FAQs, etc.", "downloadURL": "https://doi.org/10.5067/579TO87M7IZB", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "NASA's newest search and order tool for subsetting, reprojecting, and reformatting data.", "downloadURL": "https://search.earthdata.nasa.gov/search?q=NSIDC-0793+V001", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}, {"@type": "dcat:Distribution", "description": "Search and filter data files using a map-based interface", "downloadURL": "https://nsidc.org/data/data-access-tool/NSIDC-0793/versions/1/", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}, {"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5067%2F579TO87M7IZB", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}], "identifier": "C3177912929-NSIDC_ECS", "issued": "1972-09-15", "keyword": ["climate-indicators", "cryospheric-indicators", "earth-science"], "landingPage": "https://doi.org/10.5067/579TO87M7IZB", "language": ["en-US"], "modified": "2025-07-17", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA NSIDC DAAC"}, "spatial": "-94.4 58.33 11.32 81.51", "temporal": "1972-09-15T00:00:00Z/2022-02-15T23:59:59.999Z", "theme": ["geospatial"], "title": "MEaSUREs ITS_LIVE Greenland Monthly 120 m Ice Sheet Extent Masks, 1972-2022 V001"}
