Daily Reference (RET) and Potential (PET) Evapotranspiration data over Florida, 2018

Potential evapotranspiration (PET), and reference evapotranspiration (RET) are estimated at an approximately 2-kilometer spatial grid and daily time-scale from January 1, 2018 to December 31, 2018 for the entire State of Florida.
Missing values are indicated with -9999.99. Missing values are due to unavailable solar radiation data, derived from the GOES satellite. Potential and reference evapotranspiration were computed on the basis of albedo, solar radiation, and meteorological data observed at weather stations. Solar radiation data obtained from Geostationary Operational Environmental Satellites (GOES) were used to estimate daily PET and RET at grid points. Albedo at grid points was computed on the basis of observations from the Moderate Resolution Imaging Spectrometer (MODIS) satellite.Meteorological data for 2018 was interpolated to grid points using a radial basis function.
