Recent \napplications for groundwater appropriations from Dixie Valley, Nevada, \na primarily undeveloped basin neighboring the Carson Desert to the \neast, have prompted a reevaluation of the quantity of naturally \ndischarging groundwater.The objective of this study was to develop \na new, independent estimate of groundwater discharge by \nevapotranspiration (ET) from Dixie Valley using a combination of \neddy-covariance evapotranspiration measurements and multispectral \nsatellite imagery. Mean annual groundwater ET (ETg) was estimated \nduring October 2009-2011 at four eddy covariance sites.  Two \nsites were located in phreatophytic shrubland dominated by \ngreasewood and two were located on a playa.  Estimates were scaled to \nthe basin level by combining remotely sensed imagery with field \nreconnaissance and site-scale ETg estimates.The Enhanced Vegetation \nIndex (EVI) was calculated for 10 Landsat 5 Thematic mapper scenes \nand combined with brightness temperature in an effort to reduce \nconfounding (high) EVI values resulting from forbes and cheat grass \nin sparsely vegetated areas, and biological soil crusts from bare soil \nto densely vegetated areas. The resulting EVI/TB images represented \nby this dataset were used to calculate ET units and scale actual \nand potential ETg to the basin level.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9O1CWBD", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.7eae176b-67a7-425f-b4dc-fe9330a9bf5e.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_7eae176b-67a7-425f-b4dc-fe9330a9bf5e", "keyword": ["Churchill County", "Dixie Valley", "ET", "ET unit", "Evaporation", "Evapotranspiration", "Great Basin", "Groundwater", "Groundwater discharge", "Nevada", "Pershing County", "Phreatophyte", "Transpiration", "USGS:7eae176b-67a7-425f-b4dc-fe9330a9bf5e", "environment", "geoscientificInformation", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-118.161709, 39.627368, -117.583859, 40.155704", "theme": ["geospatial"], "title": "Temperature Normalized Enhanced Vegetation Index for Dixie Valley, Churchill County, Nevada"}
