Considerable gaps in our global knowledge of potential groundwater accessibility

This data contains the model ensemble mean of water table depth in meter of four global steady-state groundwater models. The spatial resolution is 5 arc-minutes (~9 by 9 km at the Equator). Models with higher resolution were aggregated to this resolution using the mean. The Models do not contain any anthropogenic influences. The uncertainty in water table depth (m) is based on the range (Max - Min) of the ensemble. Robert Reinecke 2024
