(co-organized by GD) Event Information The Earth's rotation changes on a wide range of time scales, reflecting the wide range of processes that are affecting it, from external tidal forces to surficial processes involving the atmosphere, oceans, and hydrosphere to internal processes acting both at the core-mantle boundary as well as within the solid Earth itself. In addition, the periods of the resonances in the Earth's rotation, including the Chandler wobble, the Free Core Nutation, the Free Inner Core Nutation, and the inner core wobble, depend upon the internal structure and constitution of the Earth. Observations of the Earth's rotation can therefore be used to place constraints on a wide range of dynamical processes of the solid Earth, including glacial isostatic adjustment, mantle anelasticity, core-mantle coupling, core flattening, core angular momentum, torsional oscillations of the core, the tilt and rotation of the inner core, and the strength of the magnetic field at the inner core and core-mantle boundaries. This session will be a forum for discussing the use of Earth rotation measurements to constrain the structure and dynamical processes of the Earth.
