Abstract

New methods estimating the amount of water storage on Earth have evolved over the years. One of them utilizes the gravitational field variation observed from the GRACE satellite. Compared to conventional methods such as water balance analysis, the method makes it simple and straightforward to obtain the terrestrial water storage change (TWSC). Previous studies show that there is a discrepancy between GRACE-based and water balance-based estimates especially in wet periods. Along with precipitation and evapotranspiration, it is common that runoff data needed for the water balance analysis are obtained from GLDAS (Global Land Data Assimilation System). In this study, GLDAS runoff data are replaced with hydrologic simulation results with such anticipation that local geomorphologic and hydrologic characteristics can be better incorporated. In an application to a relatively small basin during a wet period, GLDAS- and simulation-based TWSCs showed values 2.73~3.58 times higher than the GRACE-based estimate. It implies that the GRACE-approach underestimates TWSC during wet periods. It also suggests the need for correction factors to adjust the GRACE-based estimates in the rainy season.
