Subject: Earth Rotation Session at Fall AGU Meeting


Dear Colleagues -

As part of the 2009 Fall Meeting of the AGU that will be held in San
Francisco, California during 14-18 December 2009 there will be a
session on "The Estimation, Prediction, and Excitation of Earth
Orientation Variations. 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. We are
developing a rich session that will cover all aspects of the Earth's
rotation including its excitation and the acquisition, reduction,
combination, and prediction of the EOPs. We hope that you will be
able to join us in San Francisco for this exciting session.  More
information about the 2009 Fall Meeting of the AGU can be obtained
from its web site at <http://www.agu.org/meetings/fm09/>.

Please note that the deadline for submitting abstracts is 03
September 2009.

Hope to see you in San Francisco!

Best regards,
Richard

G16: The Estimation, Prediction, and Excitation of Earth Orientation
Variations

Given current capabilities in space-geodesy, observations of Earth
Orientation (that is precession/nutation, rotation, and polar motion)
are being made with higher temporal resolution and with greater
accuracy than before, allowing smaller scale fluctuations to be
detected with finer resolution than was possible before. Such
fluctuations are the rotational response of the Earth to forcing by
geophysical fluids, and so information about the excitation of Earth
orientation by the atmosphere, oceans, cryosphere, hydrosphere and
core-mantle interactions is sought here. Relevant geophysical
observations may be both in-situ and remotely sensed, and are often
combined through sophisticated models and data assimilation schemes.
In this session, we wish to focus on Earth orientation, its
excitation, estimation and prediction. Recent advances in geodetic
observational techniques, Earth orientation predictive capability,
and the use of Earth orientation parameters to transform between the
Celestial and Terrestrial Reference frames is welcome in this session.
