Satellite Gravity and the Geosphere: Contributions to the Study of the SolidEarth and Its FLuid Envelope

摘要

Based on an analysis of planned or envisioned mission concepts and the results offorward modeling, the report identifies the research priorities of a dedicated satellite gravity mission: ocean dynamics, including deep ocean circulation; continental water variation, including seasonal and annual variations in snow pack and groundwater level; sea-level change, including changes in the mass of the Greenland and Antarctic ice sheets; and post-glacial rebound. Satellite gravity measurements, in conjunction with other data, would also lead to improved geophysical models of the Earth's crust, mantle, and atmosphere.
