Project Details
Description
Temporal variations of the earth gravity field reflect, among other effects, temporal changes in total water
storage (TWS) in the earth system. However, instrument accuracy has been insufficient in the past to measure
the minimal changes in the gravitational acceleration due to changes in water storage. A new generation of
outdoor absolute and relative gravimeters is now available (Scintrex A-10, Scintrex CG-5) which are accurate
enough to monitor water storage changes in typical hydrological systems. Moreover, the Gravity Recovery and
Climate Experiment (GRACE) has provided space-borne gravity measurements with unprecedented accuracy
and global coverage.
