The detectability of the interannual variations of terrestrial water storage in 70 river basins acquired by satellite gravimetry was investigated using the Japan Meteorological Agency?Simple Biosphere (JMA?SiB) model. Terrestrial water storages for the monthly, seasonal, and annual averaging periods were computed from the output of a 10 year integration performed by the JMA-SiB model. The satellite specification was assumed to be the same as for the NASA Gravity Recovery and Climate Experiment (GRACE). The total errors in the satellite-gravimetry-derived terrestrial water storage (including the instrument error, atmospheric error, and error due to the postglacial rebound) were computed for each period at each basin....

Groundwater storage depletion is a critical issue for many of the major aquifers in the U.S., particularly during intense droughts. The GRACE (Gravity Recovery and Climate Experiment) satellites launched in 2002, with sensors designed to measure changes in the Earth’s gravitational field at large spatial scales (≥ ~200,000 km2). These changes are primarily driven by changes in water storage on the Earth’s surface. Estimates of groundwater storage changes based on these gravity measurements have attracted considerable media attention in the U.S. and globally. However, groundwater storage changes are computed indirectly by subtracting snow, surface water, and soil moisture storage from the total water storage monitored...
