Mass transport between the atmosphere, oceans and solid Earth produces changes in the solid Earth's rotation and gravity field which can be measured by modern space geodetic techniques. Changes in the Earth's gravity field arise from mass redistribution within the Earth system via complicated processes and interactions between the solid Earth, hydrosphere, cryosphere, atmosphere, and ocean. Temporal gravity signals occur over a wide spectrum of time scales and its spatial scales are very broad. Some of these signals are sensitive to global and regional climate change and possibly with anthropogenic origin. Sensors such as CHAMP, GRACE and GOCE and in situ stations such as gravimeters (absolute and relative) are capable of measuring some of these signals. This session solicit papers in the above broad subject, but not limited to, scopes associated with observations, modeling, interpretation and quantitative understanding of temporal gravity field.
