Gridded potential evapotranspiration over Great Britain for the years 1961-2019 at 1 km resolution. This dataset contains two potential evapotranspiration variables calculated using the Penman-Monteith equation parameterised for well-watered short grass: daily total potential evapotranspiration (PET; kg m-2) and daily total potential evapotranspiration with interception correction (PETI; kg m-2). The data are provided in gridded netCDF files. There is one file for each variable for each month of the data set. This research has been carried out under national capability funding as part of the NERC Hydro-JULES programme (NE/S017380/1) and under the NERC Changing Water Cycle program (NE/I006087/1) Full details about this dataset can be found at https://doi.org/10.5285/8651771d-aa6d-4d0f-8bcd-b3be1f733852
