<jats:p>This study presents the first comparison of seasonal groundwater storage (GWS) variations derived from GRACE satellite data with groundwater‐level measurements in the High Plains Aquifer, USA (450,000 km<jats:sup>2</jats:sup>). Correlation between seasonal GRACE terrestrial water storage (TWS) and the sum of GWS estimated from field measurements (2,700 wells) and soil moisture (SM) simulated by a land surface model is high (R = 0.82). Correlation between GRACE‐derived and measured GWS is also significant (R = 0.58). Seasonal GRACE‐derived TWS and GWS changes were detectable (≥ uncertainty) in 7 and 5 out of 9 monitored periods respectively whereas maximum changes (between winter/spring and summer/fall) in TWS and GWS were detectable in all 5 monitored periods. These results show the potential for GRACE to monitor GWS changes in semiarid regions where irrigation pumpage causes large seasonal GWS variations.</jats:p> |
