Since its launch in March 2002, the Gravity Recovery and Climate Experiment (GRACE) has provided a global mapping of the time-variations of the Earth’s gravity field. Tiny variations of gravity from monthly to decadal time scales are mainly due to redistributions of water mass inside the surface fluid envelops of our planet (i.e., atmosphere, ocean and water storage on continents). In this article, we present a review of the major contributions of GRACE satellite gravimetry in global and regional hydrology. To date, many studies have focused on the ability of GRACE to detect, for the very first time, the time-variations of continental water storage (including surface waters, soil moisture, groundwater, as well as snow pack at high latitudes) at the unprecedented resolution of ~400–500 km. As no global complete network of surface hydrological observations exists, the advances of satellite gravimetry to monitor terrestrial water storage are significant and unique for determining changes in total water storage and water balance closure at regional and continental scales.

Review on Estimation of Land Surface Radiation and Energy Budgets From Ground Measurement, Remote Sensing and Model Simulations (2010, methodology): “dS/dt can be derived using gravity anomaly measurements, such as the Gravity Recovery and Climate Experiment (GRACE) launched in March 2002 [153], [154], P is regularly retrieved using a variety of techniques from multi-sensor microwave and”
Ensemble prediction and intercomparison analysis of GRACE time‐variable gravity field models (2014, methodology): “…certainly desirable but will depend upon the application, and the improvement is still significantly less than the current gap between GRACE and model output which commonly shows an amplitude bias and phase shift from the GRACE data [Ramillien et al., 2008; Schmidt et al., 2008; Gao et al., 2010].”
Groundwater depletion in the Middle East from GRACE with implications for transboundary water management in the Tigris-Euphrates-Western Iran region (2013, background): “Recent studies have demonstrated that water storage changes can be inferred from the GRACE data with sufficient resolution and accuracy to benefit water management [Yeh et al., 2006; Rodell et al., 2007; Ramillien et al., 2008; Zaitchik et al., 2008].”
