Included with this data set are two- and three-dimensional microstructural analysis of DMP/DEP casted and un-casted snow samples, available as .xlsx and .txt file, and visual representations of the three-dimensional snow structure, available is .bmp image files. Containers of snow were collected at 6 snow pits in approximately 17 cm intervals. There were approximately 5-8 discrete containers per pit and each container had an ~2 cm overlap with the sample below. A 6-cm section of snow was dissected from each container of snow, which were analyzed in ~2 cm sub-sections. Each sub-section was scanned in three intervals using a micro-CT instrument. The three interval scans comprise multiple slices, and were combined into the reconstructed final scan used for calculating the snow microstructural data.", "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/SO0GIXLAK2SG", "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=SNEX20_GM_CTSM+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/SNEX20_GM_CTSM/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%2FSO0GIXLAK2SG", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}], "identifier": "C2695623073-NSIDC_ECS", "issued": "2020-02-03", "keyword": ["cryosphere", "earth-science", "snow-ice"], "landingPage": "https://doi.org/10.5067/SO0GIXLAK2SG", "language": ["en-US"], "modified": "2025-07-17", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA NSIDC DAAC"}, "spatial": "-108.228389 39.005111 -108.110485 39.065321", "temporal": "2020-02-03T00:00:00Z/2020-02-08T23:59:59.999Z", "theme": ["SnowEx", "geospatial"], "title": "SnowEx20 Grand Mesa IOP Computed Tomography Snow Microstructure V001"}
