Data sets of actual evapotranspiration rates from 2000 to 2017 for basins in the Tampa Bay Water (TBW) area, calculated using the water-balance method, the bias-corrected Operational Simplified Surface Energy Balance (SSEBop) model, and the land-use crop coefficients model.

Actual evapotranspiration (ETa) rates from the Operational Simplified Surface Energy Balance (SSEBop) method, before and after bias corrections (Sepúlveda, 2021), are presented for basins located in the Tampa Bay Water (TBW) area. The SSEBop annual rates are provided at about a one square-kilometer scale from 2000 to 2017. Annual ETa rates calculated from the application of the water-balance method (wbETa) to 8 basins in the TBW area and annual land-use ETa (luETa) rates calculated from monthly average crop coefficient ratios are also provided in this data set. A GIS shapefile provides land-use type and annual ETa rate for each year of record. Data are tabulated in spreadsheets for each basin and are referred to by the name between parenthesis: Little Manatee River basin (02300500), North Prong Alafia River basin (02301000), South Prong Alafia River basin (02301300), Hillsborough River above Crystal Spring basin (02301990), Blackwater Creek near Knights basin (02302500), Cypress Creek and Trout Creek basin (02303800), Sweetwater Creek near Tampa basin (02306647), and Anclote River near Elfers basin (02310000). Inflows and outflows from various sources in the water-balance equation used to calculate annual average wbETa rates for each basin are presented in this dataset.
