Long term average (LTA) Potential Groundwater Recharge (GWRpot) for the European domain at 1 km spatial resolution for the period 1981-2010. The LTA GWRpot 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. The TACTIC series of gridded datasets for estimation of GWRpot included two versions of GWRpot. The current dataset is the GWRpot =Peff*Rcoef. The other is GWRpot_biacorr= Peff_biascorr*Rcoef, adjusted to other Peff estimates from seven national pilots in Europe. Urban areas are masked out and not represented in the gridded dataset. All units are mm/year for the period 1981-2010.

Long term average (LTA) Effective Precipitation (Peff) for the European domain at 1 km spatial resolution for the period 1981-2010. The Peff estimate is based on E-Obs precipitation records and a merged AET estimate based on the Budyko method and satellite estimates. The LTA Peff 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. The TACTIC series of gridded datasets for estimation of GWRpot included two versions of Peff. The current dataset is the Peff_biacorr= (Precipitation-AET)*1.26, adjusted to other Peff estimates from seven national pilots in Europe. The other is Peff = Precipitation-AET. Urban areas are masked out and not represented in the gridded dataset. All units are mm/year for the period 1981-2010.

Groundwater Recharge Coefficient (Rcoef) for the European domain at 1 km spatial resolution for the period 1981-2010. The Rcoef estimate is based on a machine learning approach trained against gridded Rcoef estimates from seven national pilots in Europe. The Rcoef 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. Rcoef is a unitless ratio representing the period 1981-2010.

This dataset consists of gridded estimates of travel times for nitrate in the unsaturated zone for Great Britain (UK), France, the Netherlands, Denmark, Croatia and Slovenia. Data for Croatia and Slovenia are presented from a regional scale pilot study, with data from the remaining countries at the national scale. The dataset was developed in Work Package 5 of the GeoERA Groundwater project HOVER.
