The attraction of water - Using GRACE satellite gravity data to improve our understanding of the global water cycle

The gravity satellite mission GRACE (Gravity Recovery and Climate Experiment) provides a new type of data for integrated  Earth system research including climate studies, ocean and sea level research, large-scale hydrological modeling and solid-Earth geophysics. Time-variable gravity enables, for the first time, a direct measurement of the amount of  water mass that is redistributed at or near the surface of the Earth through the hydrological cycle and by oceanic
 and atmospheric circulation. In this presentation I will briefely explain the measurement principle of GRACE and will describe the chances this type of measurement offers for water cycle and climate studies. Applications include the quantification of ice mass changes resulting in sea level rise, the validation of hydrological model output, and the identification of anthropogenic influences on the water cycle.
