Environment Agency Potential Evapotranspiration Dataset

Potential Evapotranspiration (PET) is the amount of evaporation which would occur if there was an unlimited supply of water. This dataset represents Potential Evapotranspiration for well watered grass and is available either with an Interception element (PETI) or without one (PET).
The dataset has been calculated from homogenised climate station data, gridded to a 1km grid. The dataset starts in 1961, is available on a water day (09:00 to 09:00 on the following day) timestep and is updated frequently.
