THIS DATASET HAS BEEN SUPERSEDED. The latest version is Potential evapotranspiration derived from HadUK-Grid 1km gridded climate observations 1969-2021 (Hydro-PE HadUK-Grid)
This data has been superseded due to errors in the data. Intercepted precipitation was not always limited to the total amount of precipitation that fell, and so occasionally reported slightly higher PETI, mostly in the summer months. Also there was an occasional error in interpolation from monthly to daily data affecting both the PET and PETI calculations, mostly in the winter months (e.g. negative sunshine hours). The newer version corrects these errors.
