Long term average (LTA) actual evapotranspiration (AET) for the European domain at 1 km spatial resolution for the period 1981-2010. The AET estimate is based on merging Budyko estimates and satellite estimates. The LTA AET data set i part of a series of gridded datasets established in the TACTIC project for estimating Potential Groundwater Recharge (GWRpot). The data available are AET, Effective precipitation (Peff=Precipitation-AET), Groundwater Recharge coefficient (Rcoef defined as the ratio: Peff / GWRpot ) The Potential Groundwater Recharge GWRpot = (Precipitation-AET)*Rcoef
Urban areas are masked out and not represented in the gridded dataset.
