     abstract = "{A method to downscale annual groundwater storage variations from large-
        scale, satellite-derived estimates to individual aquifers is
        presented, employing a simple linear regression approach based
        on the water balance principle. The method relies on groundwater
        storage changes derived from the gravity recovery and climate
        experiment (GRACE). Seven alluvial aquifers, ranging in area
        from approximately 145 to 1300 km$^{2}$ in Fars Province, Iran,
        were selected as case studies to evaluate the applicability of
        the proposed downscaling method. The results indicate that
        groundwater storage at the GRACE scale
        (\raisebox{-0.5ex}\textasciitilde 31,416 km$^{2}$) has depleted
        by 229 million cubic meters (MCM) per year during the study
        period (2002{\textendash}2015). The correlation coefficients
        between downscaled and actual groundwater storage depletions
        varies from 0.655 to 0.891, with an average of
        \raisebox{-0.5ex}\textasciitilde 0.82 across the seven aquifers,
        demonstrating the method's ability to provide acceptable
        downscaling results. Downscaling results indicate that the
        alluvial aquifers of Aspas, Namdan, Beiza-Zarghan, Dehbid,
        Abadeh-Eghlid, Bakan, and Sidan-Farugh have experienced
        groundwater storage depletions of 17.71, 34.49, 46.21, 13.88,
        14.11, 6.78, and 22.62 MCM per year, respectively, from 2002 to
        2015, which correspond to water table declines of 0.915, 0.656,
        0.822, 0.538, 0.725, 1.395, and 1.435 m/year, respectively. As a
        final point, this study proposes a downscaling method that can
        be applied to address groundwater storage variations at aquifer
        scales, particularly in regions with unavailable or limited
        data.}",
