The success of the recent GRACE satellite gravity mission has demonstrated the feasibility to directly measure mass redistribution in the Earth?s system from space. In particular the redistribution of water can be observed, which is critical for monitoring key climate indicators such as ice-sheet mass balance, terrestrial water-storage change, sea-level rise, and ocean circulation. The key objective of this project is to study some key elements and parameters of a future GRACE follow-on mission to be launched in 10-15 years from now. The accuracy of the new mission must exceed that of GRACE by a factor of 10 to 100.
