Data are confined to 61-72 deg N, 30-50 deg W, above 1700 m elevation. The addition of GEOSAT Geodetic Mission (GM) data results in twice as many crossover points and 50% greater coverage than previous studies. Coverage above 2000 m elevation is improved to 90%, and about 75% of the area between 1700 m and 2000 m is now covered. Data are in ASCII text format, available via FTP, and consist of elevation change rate (dH/dt, cm/year) and corresponding error estimates in 50 km grid cells.", "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/C1386204165-NSIDCV0.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://daacdata.apps.nsidc.org/pub/DATASETS/parca/nsidc0223_elevation_change", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.5067/10JHXYLCEFVX", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://nsidc.org/sites/default/files/nsidc-0223-v001-userguide.pdf", "format": "PDF", "mediaType": "application/pdf"}], "identifier": "10.5067/10JHXYLCEFVX", "keyword": ["earth-science-glaciers-ice-sheets-cryosphere-glacier-elevation-ice-sheet-elevation", "earth-science-glaciers-ice-sheets-cryosphere-ice-sheets", "earth-science-glaciers-ice-sheets-terrestrial-hydrosphere-glacier-elevation-ice-sheet-elevation", "earth-science-glaciers-ice-sheets-terrestrial-hydrosphere-ice-sheets"], "license": "https://www.usa.gov/government-works", "modified": "2026-08-18", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA NSIDC DAAC;UMO-COLUMBIA"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -52.0, \"NorthBoundingCoordinate\": 72.0, \"EastBoundingCoordinate\": -30.0, \"SouthBoundingCoordinate\": 61.0}]]", "temporal": "1978-06-28/1989-12-31", "theme": ["Earth Science"], "title": "Elevation Change of the Southern Greenland Ice Sheet from 1978-88, Version 1"}
