WebJun 23, 2015 · As valuable as GRACE’s groundwater data is, it has a crucial gap: it cannot show the total volume of groundwater available in the aquifers it tracks, only the rate of decline. Without knowing when the aquifers will go dry, or when water tables will sink so low that they are effectively inaccessible, users and water managers are blind to the ... WebNov 5, 2024 · GRACE satellite data are widely used to estimate groundwater storage (GWS) changes in aquifers globally; however, comparisons with GW monitoring and modeling data are limited. Here we compared GWS changes from GRACE over 15 yr (2002–2024) in 14 major U.S. aquifers with groundwater-level (GWL) monitoring data in …
