This data release provides global, field\u2011scale ET data generated from Landsat observations using the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Science Processing Architecture (ESPA). The dataset includes cloud\u2011free Landsat scenes from 1982 (Landsat 4) through the present Landsat missions. ET is produced as a Provisional Level\u20113 Science Product using the Operational Simplified Surface Energy Balance (SSEBop) model. Model inputs include Landsat surface temperature, reference ET, vegetation index, and net radiation.\nThe data represent on\u2011demand ET outputs processed for individual Landsat overpasses and delivered as tiled geospatial products. These ET data support applications in water\u2011use estimation, agricultural monitoring, hydrologic assessment, and land\u2011surface process studies. The release documents the processing workflow, model inputs, and data characteristics to enable consistent interpretation and use of the ET products.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13FNBZF", "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.69f4a182b66b0122e4360df6.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_69f4a182b66b0122e4360df6", "keyword": ["EROS Science Processing Architecture", "Essential climate product", "Landsat", "OpenET", "SSEBop", "USGS:69f4a182b66b0122e4360df6", "geoscientificInformation", "image collections", "inlandWaters", "multispectral imaging", "on demand", "overpass date", "provisional Evapotranspiration"], "modified": "2026-05-27T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-180.0000, -90.0000, 180.0000, 90.0000", "theme": ["geospatial"], "title": "ESPA processing workflow for on-demand global Landsat evapotranspiration"}
