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 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...

This data set provides reference evapotranspiration (ETo) and actual evapotranspiration (ETa) rates calculated at 24 micrometeorological evapotranspiration flux (MEF) stations (mETa) in Florida for each month for which the station was in operation between 2000 to 2017 (Sepúlveda, 2021). The MEF station name, location, generalized land-use type, monthly and annual Operational Simplified Surface Energy Balance (SSEBop) ETa rates before and after bias corrections, monthly and annual reference ET rates (ETo) at each MEF station are also provided in addition to mETa rates. Ratios of monthly mETa to ETo rates were calculated for each generalized land-use type. Linear regressions of mETa minus SSEBop ETa rates, referred...
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...
Actual evapotranspiration (ETa) rates from the Operational Simplified Surface Energy Balance (SSEBop) method, before and after bias corrections, are presented for basins located wholly or partially within the St. Johns River Water Management District (SJRWMD). 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 19 basins in the SJRWMD 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...
Measured AET monthly rates in file AET_Monthly_Totals.csv were calculated at these ET monitoring stations in central and east-central Florida: Duda Farms, Blue Cypress, Reedy Lake, Orlando Urban, Disney Preserve, Lyonia Preserve. The monthly AET rates measured at these sites are compared side by side with the monthly AET rates calculated using the SSEBop method. The SSEBop AET rates were obtained from Gabriel Senay, one of the authors of Savoca and others, 2013, where the SSEBop methodology is explained. The measured AET monthly rates at the ET sites are presented as another way to assess the reliability of the SSEBop AET rates. The Florida ET network grid pixel numbers used for this comparison are: Duda Farms -...

Actual evapotranspiration (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 based method, provided in shapefiles AET_SJR_Basin_Cells, are explained in the metadata file AET_SJR_Basins. The calculation of the annual average AET rates using a water-budget analysis (WBA) is explained in this metadata file referring to csv files for the eight basins in east-central and northeast Florida. A comparison of the average annual SSEBop AET rates and those derived from the WBA is then possible by using the average annual AET rates for each basin. The eight basins for which the WBA analysis was completed are: 1. St. Johns near...
