Two of the snow depth maps coincide temporally with the 2017 NASA SnowEx Grand Mesa field campaign, providing a comparison between the satellite derived snow depth and in-situ snow depth measurements. The VHR stereo images were acquired each year between 2016 and 2022 during the approximate timing of peak snow depth by the Maxar WorldView-2, WorldView-3, and CNES/Airbus Pl\u00e9iades-HR 1A and 1B satellites, while lidar data was sourced from the USGS 3D Elevation Program.", "distribution": [{"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5067%2F7QCNCHVQMCI8", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "Search and filter data files using a map-based interface", "downloadURL": "https://nsidc.org/data/data-access-tool/SNEX_HRSI_SD_DEM_CO/versions/1/", "format": "HTML", "mediaType": "text/html", "title": "Download 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=SNEX_HRSI_SD_DEM_CO+V001", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}, {"@type": "dcat:Distribution", "description": "Includes a user's guide, supplemental documents like ATBDs and academic papers, How Tos, FAQs, etc.", "downloadURL": "https://doi.org/10.5067/7QCNCHVQMCI8", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}], "identifier": "C2849456374-NSIDC_ECS", "issued": "2016-02-19", "keyword": ["cryosphere", "earth-science", "land-surface", "snow-ice", "topography"], "landingPage": "https://doi.org/10.5067/7QCNCHVQMCI8", "language": ["en-US"], "modified": "2025-07-17", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA NSIDC DAAC"}, "spatial": "-108.382269 38.785954 -107.747336 39.216156", "temporal": "2016-02-19T00:00:00Z/2022-05-11T23:59:59.999Z", "theme": ["SnowEx", "geospatial"], "title": "SnowEx Colorado 3M Snow Depth Time Series and DEMs from High-Resolution Satellite Image Pairs V001"}
