Thaw and freezing depths were calculated over the study area with a resolution of 25 km x 25 km. Data extend from September 1998 through December 2000. A finite-difference model for one-dimensional heat conduction with phase change calculates daily thaw and freezing depths, based on data of snow water equivalent, soil temperature, soil dry-bulk density, and soil water content. Data are in space-delimited ASCII text format and are available via FTP.", "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/C1386206888-NSIDCV0.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "http://nsidc.org/data/docs/fgdc/ggd619_thawdepth_arctic/index.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.7265/whf6-t406", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://nsidc.org/forms/GGD619_or.html?major_version=1", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.7265/whf6-t406", "keyword": ["earth-science-frozen-ground-cryosphere-active-layer", "earth-science-frozen-ground-cryosphere-seasonally-frozen-ground", "earth-science-frozen-ground-land-surface-active-layer", "earth-science-frozen-ground-land-surface-seasonally-frozen-ground", "earth-science-snow-ice-cryosphere-freeze-thaw", "earth-science-snow-ice-terrestrial-hydrosphere-freeze-thaw"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-23", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NSIDC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -180.0, \"NorthBoundingCoordinate\": 90.0, \"EastBoundingCoordinate\": 180.0, \"SouthBoundingCoordinate\": 66.33}]]", "temporal": "1998-09-01/2000-12-31", "theme": ["Earth Science"], "title": "Modeled Daily Thaw Depth and Frozen Ground Depth, Version 1"}
