Earth Rotation Session at AGU Fall Meeting


Dear Colleagues -

As part of the 2019 Fall Meeting of the AGU that will be held in San
Francisco during 9-13 December 2019 there will be a session on "Earth
and Planetary Rotation: Nutation, Wobble, and Spin". The description of
the session is given below. On behalf of the conveners I would like to
draw your attention to this session and encourage you to participate in
it. More information about the 2019 Fall Meeting can be obtained from
its web site at <https://www2.agu.org/fall-meeting>.

Please note that abstracts must be submitted to AGU by July 31, 2019.

Hope to see you in San Francisco!

Best regards,
Richard Gross


G003: Earth and Planetary Rotation: Nutation, Wobble, and Spin

The rotation of the Earth and planets changes on a wide range of time
scales, reflecting the wide range of processes affecting it, from
external tidal forces to surficial processes involving the atmosphere,
oceans, and hydrosphere (including climate) to internal processes acting
both at internal boundaries as well as within the solid body itself. In
addition, the frequencies of resonances depend upon the internal
structure and constitution of the rotating body. Observations of
rotation can therefore be used to place constraints on a wide range of
dynamical processes. This session is a forum for discussing the use of
rotation measurements to constrain the structure and dynamical processes
of the Earth and other planets. The session also welcomes contributions
about recent advances in theoretical and empirical modeling of Earth and
planetary rotation including updates to observing systems, data,
products, predictions and conventions relating to Earth and planetary
rotation.
