Terrestrial water availability storage is the sum of groundwater, soil moisture, snow and ice, surface waters, and wet biomass, expressed as an equivalent height of water. GRACE measures changes in the terrestrial water cycle by assessing small changes in Earth's gravity field. This observation-based assessment of how the world's water cycle is responding to human impacts and climate variations provides an important tool for evaluating and predicting emerging threats to water and food security.", "distribution": [{"@type": "dcat:Distribution", "description": "Documentation Page", "downloadURL": "https://sedac.ciesin.columbia.edu/data/set/sdei-trends-freshwater-availability-grace/docs", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "Sample browse graphic of the data set.", "downloadURL": "https://sedac.ciesin.columbia.edu/downloads/maps/sdei/sdei-trends-freshwater-availability-grace/sdei-trends-freshwater-availability-grace-global-2002-2016-thumbnail.jpg", "format": "JPEG", "mediaType": "image/jpeg", "title": "Get a related visualization"}, {"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.7927%2FH4TT4P2C", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "Web Map Service Page", "downloadURL": "https://sedac.ciesin.columbia.edu/data/set/sdei-trends-freshwater-availability-grace/maps/services", "format": "HTML", "mediaType": "text/html", "title": "Use Web Map Service (WMS) to download the dataset's data"}], "identifier": "C1617586061-SEDAC", "issued": "2019-05-22", "keyword": ["earth-science", "ground-water", "snow-ice", "surface-water", "terrestrial-hydrosphere"], "language": ["en-US"], "modified": "2025-07-17", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "SEDAC"}, "references": ["https://doi.org/10.7927/h4q23xbz"], "spatial": "-180.0 -90.0 180.0 90.0", "temporal": "2002-01-01T00:00:00Z/2016-12-31T00:00:00Z", "theme": ["SDEI", "geospatial"], "title": "Trends in Global Freshwater Availability from the Gravity Recovery and Climate Experiment (GRACE)"}
