GIS shapefile: Actual evapotranspiration rates from 2000 to 2017 for basins in Florida and parts of Alabama and Georgia, calculated using the water-balance method, the bias-corrected Operational Simplified Surface Energy Balance (SSEBop) model, and the land-use crop coefficients model.

Annual actual evapotranspiration (ETa) rates in 55 basins in Florida and parts of Alabama and Georgia were evaluated for 2000-17 using the Operational Simplified Surface Energy Balance (SSEBop) model at about a one-square kilometer resolution (Sepúlveda, 2021). SSEBop ETa rates were bias corrected using ETa rates computed from weather observations at 24 micrometeorological evapotranspiration flux (MEF) stations (mETa), stratified by land-use type. Uncorrected and bias-corrected SSEBop ETa rates were evaluated by comparison with independent estimates based on a crop-coefficient method for generalized land-use types (luETa) and a water-balance method for each basin (wbETa). This metadata file summarizes a GIS shapefile with basin characteristics for each of the 55 basins, along with average annual estimates of SSEBop ETa (uncorrected and bias-corrected), and differences (residuals) from average annual estimates based on luETa rates and wbETa rates for each basin.
