Data sets of actual evapotranspiration rates from 2000 to 2017 for basins in the Northwest Florida Water Management District (NWFWMD), 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 wholly or partially within the Northwest Florida Water Management District (NWFWMD) and parts of Alabama and Georgia. 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 5 basins in the NWFWMD 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: Lower Ochlockonee basin (Lower_Ochlockonee), Apalachicola – Chipola River basin (Apalachicola_Chipola), Lower Choctawhatchee River basin (Lower_Choctawhatchee), Yellow River basin (Yellow), and Escambia – Perdido River basin (Escambia_Perdido). 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.
The purpose of this data release is to present the bias corrected annual Operational Simplified Surface Energy Balance or SSEBop ETa rates, the annual wbETa rates calculated from the water-balance method for the basins in the NWFWMD area, and the annual land-use ETa (luETa) rates calculated from monthly average crop coefficient ratios for the 2000 to 2017 period.

The SSEBop rates are based on the SSEBop method described in: Senay, G.B., Bohms, S., Singh, R.K., Gowda, P.H., Velpuri, N.M., Alemu, H., and Verdin. J.P., 2013, Operational Evapotranspiration Mapping Using Remote Sensing and Weather Datasets: A New Parameterization for the SSEB Approach: Journal of the American Water Resources Association, v. 49, no. 3, p. 577-591, DOI: 10.1111/jawr.12057.

This ArcGIS 10.7.1 polygon shapefile lists land-use type and annual SSEBop ETa rates after bias corrections at about a one square-kilometer scale for the NWFWMD area and parts of Alabama and Georgia. The method used for bias correction, based on comparison of SSEBop ETa rates with ETa rates computed using micrometeorological evapotranspiration flux (MEF) station data, is discussed by Sepúlveda (2021).

These Microsoft Excel spreadsheets list the annual average change in basin storage calculated from annual differences in water levels averaged over the number of surficial wells with water-level data in the basin. Annual changes in water levels are calculated by subtracting the mean water level at the beginning of the year (January 1) from the mean water level at the end of the year (December 31) for the first year. Annual changes for all other years were calculated from the end of the previous year (December 31) to the end of the following year (December 31).
Water level differences between end of year and beginning of year are averaged over the number of wells.

These spreadsheets list the water-balance method flow term of rainfall. Rainfall in millimeters per month for each basin were obtained from the USGS Geo Data Portal https://cida.usgs.gov/gdp/ using Parameter-Elevation Regressions on Independent Slopes Model (PRISM; Daly and others, 2008) to calculate rainfall in inches per year for the basin. A single polygon was used for the appropriate basin from the Basins_Shapefiles presented in this dataset.

These spreadsheets list the water-balance flow term of net stream outflow. Streamflow entering the basin is considered inflow and streamflow leaving the basin at the basin outlet is considered outflow. Flows from streams that originate inside the basin are not considered inflows if the Floridan aquifer is part of the control volume (Sepúlveda, 2021). Net stream outflow to the basin is calculated in cubic feet per second from streamflow data obtained from NWIS (U.S. Geological Survey, 2018) gaging stations and is used to convert annual stream outflow to inches per year for the basin.
These spreadsheets convert stream outflow in cubic feet per second from NWIS (U.S. Geological Survey, 2018) to stream outflow in inches per year using the basin area.

inflow1 02358000
Maximum number of stream gaging stations in all basins, representing inflow, was 1. If no stream gaging station number is listed under inflow1, then all basin streamflow originates within the basin boundary. This is streamflow that crosses the basin boundary.

NetOutflow_cfs
Daily mean value of streamflow, in cubic feet per second, equal to the sum of measured outflow1 minus inflow1. Station 02359170 is outflow1 and measured flow at 02358000 is inflow1. Field outflow2 applies only to basins with two outlets, which occurred when the two disjoint areas contributing to stream outflows within the same basin could not be precisely delineated.
