title: Uncertainty in global groundwater storage estimates in a Total Groundwater Stress framework.
abstract: Groundwater resilience is defined and quantified with remote sensing from GRACETimescales of aquifer depletion are assessed as a Total Groundwater Stress ratioThe volume of usable global groundwater storage is found to be largely unknown.
