For 15 Years, GRACE Tracked Freshwater Movements Around the World
Released on May 16, 2018
NASA scientists used GRACE data to identify regional trends of freshwater movement, and combined that information with data from other satellites, climate models and precipitation measurements to determine the causes of major regional trends in freshwater storage.
The Gravity Recovery and Climate Experiment, or GRACE mission, used precise measurements of the motions of two spacecraft in Earth’s orbit to track the movement of water through the oceans, land, and atmosphere.
