SSEBop Evapotranspiration (ETa) from Landsat, 2000-2020 CONUS Monthly Actual ET

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 04:23 AM | Dataset Last Updated: July 09, 2025 at 12:00 AM
This USGS data release is a result of using the OpenET Google Earth Engine (GEE) implementation of the USGS EROS Operational Simplified Surface Energy Balance (SSEBop, Senay and others, 2013; Senay and others, 2023) Evapotranspiration (ET) model to create Actual ET (ETa) estimates from remote sensing data at 30-m spatial resolution, supporting spatiotemporal ET coupling analysis with the USGS National Hydrologic Model (NHM; Regan and others, 2019). The results are Landsat-based monthly products generated from satellite imagery with <60% cloud cover and made available as a raster image collection from 2000-2020 for the conterminous United States (CONUS). SSEBop derivatives were used within the NHM to estimate consumptive use and effective precipitation on irrigated lands. Data products are spatially constrained and provided via modified Military Grid Reference System (MGRS) tiles which is based on the Universal Transverse Mercator (UTM) projection. Please refer to the Supplemental Information element of this metadata record for further information on this data.
