Earth Rotation and Geophysical Fluids
Chair: Sigrid Böhm (TU Wien, Austria)
Vice-Chair: Christopher Dieck (United States Naval Observatory, USA)
Objectives
The objective of SC 3.3 is to serve the scientific community by supporting research and data analysis devoted to variations in Earth rotation, the gravitational field, and the geocenter caused by mass redistribution within and mass exchange among the Earth's fluid sub-systems, i.e., the atmosphere, ocean, continental hydrosphere, cryosphere, mantle, and core along with geophysical processes associated with ocean tides and the hydrological cycle. The SC contributes to accomplishing the GGOS vision of ''Advancing our understanding of the dynamic Earth system by quantifying our planet's changes in space and time'' with the quantification of the following parameters for the past, present, and future:- angular momentum exchange and mass transfer;
- deformation due to mass transfer between solid Earth, atmosphere, and hydrosphere including ice.
