This dataset contains two gridded potential evapotranspiration variables for Great Britain from 1961-2019: daily total potential evapotranspiration (PET; kg m-2 d-1) and daily total potential evapotranspiration with interception correction (PETI; kg m-2 d-1). The variables were calculated from the Climate Hydrology and Ecology research Support System meteorology dataset for Great Britain (1961-2019) [CHESS-met] gridded observed meteorological data at 1 km resolution. The units kg m-2 d-1 are equivalent to mm d-1. The data are provided in gridded NetCDF files. There is one file for each variable, for each calendar month.

Provenance & quality

This dataset was derived from the Climate Hydrology and Ecology research Support System meteorology dataset for Great Britain (1961-2019) [CHESS-met] at 1 km resolution over the United Kingdom for the years 1961-2019. The daily total potential evapotranspiration (PET; kg m-2 d-1) was calculated using the Penman-Monteith equation parameterised for a well-watered grass surface. The daily total potential evapotranspiration with interception correction (PETI; kg m-2 d-1), was calculated as PET then a correction added for interception by a grass canopy on days with non-zero precipitation.

The CHESS-met meteorological variables used were daily mean air temperature at 1.2 m (K), specific humidity at 1.2 m(kg kg-1), surface air pressure (Pa), downward longwave radiation (W m-2), downward shortwave radiation (W m-2), monthly mean wind speed at 10 m (m s-1) and precipitation (kg m-2 s-1). A description of the methodology is available in the supporting documentation.
