Contributions to Terrestrial and Global Hydrology from a Decade of GRACE Measurements
Abstract
A decade of GRACE time-variable gravity measurements has provided unprecedented insights into the dynamics of the terrestrial and global water cycles. In this presentation we review pre-launch expectations and compare them to what hydrologic information GRACE has actually provided. Examples include estimating unknown fluxes such as evapotranspiration and discharge from large river basins, remote sensing of groundwater storage changes from large aquifer systems, and tracking emerging trends in freshwater availability around the globe. Impacts on drought and flood monitoring will also be highlighted. Implications for water management, water security and water cycle change will be discussed.
