     abstract = "{Monitoring changes in groundwater storage ({\ensuremath{\Delta}}GWS) is
        critical to assess sustainability of groundwater use under
        climate variability. Satellite gravimetry from the GRACE
        missions is used to infer {\ensuremath{\Delta}}GWS by deducting
        changes in monitored or modeled water components from GRACE-
        derived changes in total water storage
        ({\ensuremath{\Delta}}TWS). As a residual parameter,
        {\ensuremath{\Delta}}GWS is highly sensitive to arithmetic
        inconsistencies and uncertainties in both GRACE data and model-
        derived inputs. Here we present a framework to evaluate the
        physical plausibility of GRACE-derived {\ensuremath{\Delta}}GWS
        estimates across 37 large global aquifer systems. The results
        show that the proportion of plausible {\ensuremath{\Delta}}GWS
        estimates per realization, derived from multiple GRACE products
        and land surface model combinations, varies from <10\% to >60\%.
        Exclusion of implausible estimates improved correlations between
        {\ensuremath{\Delta}}GWS and {\ensuremath{\Delta}}TWS
        substantially (r {\ensuremath{\geq}} 0.9, p-value <0.05) in most
        aquifers (31/37) and with in situ observations in the Bengal
        Basin (r = 0.8, p-value <0.05).}",
