Actual to reference evapotranspiration (AET/RET) ratios for several land-cover types in 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...

Actual evapotranspiration annual rates from 2000 to 2017 in basins in east-central and northeast Florida.

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...

Actual evapotranspiration (AET) monthly rates from ET stations in central Florida and corresponding simplified surface energy balance operational AET rates

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 -...

Water-budget analyses to calculate actual evapotranspiration in 8 basins in east-central and northeast Florida from 2000 to 2017

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...
