Average annual Actual Evapotranspiration (AET) rates for basins in east-central and northeast Florida from 2000 to 2017 were calculated using a water-budget balance equation. These AET rates are used to assess the reliability of the AET rates calculated using the Simplified Surface Energy Balance operational (SSEBop) method. The AET annual rates, from 2000 to 2017 for the Simplified Surface Energy Balance operational (SSEBop) method and from 2000 to 2016 for the land-cover method were provided in the shapefile AET_SJR_Basin_Cells, explained in the metadata file AET_SJR_Basins. Measured AET monthly rates in file AET_Monthly_Totals.csv were calculated at these ET monitoring stations in central and east-central Florida:...

File AET2RET_Ratios.csv lists the AET to RET (actual to reference evapotranspiration) ratios, or AET/RET, used to calculate actual evapotranspiration for each land cover type. The daily measured AET data collected at the ET stations were used to calculate the monthly totals for each month of the year. These monthly AET totals were then used to calculate the average AET/RET monthly ratios for the land cover of the ET station by dividing the AET rates by the RET rates obtained from the Florida ET network (http://fl.water.usgs.gov/et/; USGS, 2016). The land cover types represented in these data are forest, grass, marsh, open water, ridge, urban, and agriculture. The AET/RET ratios for these land cover types were presented...

The actual evapotranspiration (AET) annual rates provided in shapefiles AET_SJR_Basin_Cells are for 2 km by 2 km cells in basins in east-central and northeast Florida. The AET rates are presented in the shapefiles for two methods: the Simplified Surface Energy Balance operational (SSEBop) method and for the land-cover type (LC) method. The period of record is 2000 to 2016 for the LC-based method and from 2000 to 2017 for the SSEBop-based method. The SSEBop AET rates are based on a work by Senay and others (2013). The LC-based AET rates were calculated from the AET/RET ratios listed in file AET2RET_Ratios.csv and the annual reference ET rates from 2000 to 2016. A third method used to calculate annual average AET...

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 on the basis of ETa rates computed from weather observations at 24 micrometeorological evapotranspiration flux (MEF) stations, stratified by land-use type and referred to as mETa rates. 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). Average...
