Potential evapotranspiration (PET) and reference evapotranspiration (ETo) are estimated at an approximately 1-kilometer spatial grid and daily time-step from January 1, 2024 to December 31, 2024 for Florida, Alabama, Georgia, South Carolina, and parts of Mississippi, North Carolina, and Tennessee. PET and ETo were computed from solar radiation, meteorological data (min/max temperature, min/max relative humidity, and mean wind speed at 2-meter height), and shortwave blue-sky albedo data. Solar radiation was computed from Geostationary Operational Environmental Satellite (GOES) sensor data, blue-sky albedo was computed from the Moderate Resolution Imaging Spectrometer (MODIS) MCD43A1 BRDF/Albedo data product, and meteorological data were simulated using a high-resolution Weather Research and Forecasting (WRF) model.
