| Session Description | Earth rotation is driven by mass transport and redistribution within the Earth geophysical fluids system, including the atmosphere, hydrosphere, ocean, cryosphere, mantle and core. Global large-scale mass transport also introduces long wavelength (i.e., low-degree) gravitational change. Although relatively small, Earth rotation and low-degree gravitational changes have been measured by space geodetic techniques with increasing, unprecedented accuracy, opening up important new avenues of research that will lead to a better understanding of global mass transport processes and of the Earth’s dynamic response. This session solicits contributions ranging from geophysical interpretations of observed Earth rotation and low-degree gravitational change using advance numerical models estimates, in situ measurements, and space geodetic measurements, to geophysical applications of observed Earth rotation and low-degree gravitational change in improving the understanding of the Earth geodynamic change and global mass transport and redistribution. |
