Earth Rotation Session at AGU Fall Meeting 2013


Dear Colleagues -

As part of the 2013 Fall Meeting of the AGU that will be held in San
Francisco, California during 09-13 December 2013 I am happy to announce
there will be a session on "Earth Rotation Variations: Causes and
Consequences". 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
observing systems, theoretical developments, and advances in our
understanding of the causes of its variations. We hope that you will be
able to join us in San Francisco for this exciting session. More
information about the 2013 Fall Meeting of the AGU can be obtained from
its web site at <http://fallmeeting.agu.org/2013/>.

Please note that the deadline for submitting abstracts is 06 August
2013.

Hope to see you in San Francisco!

Best regards,
Richard Gross

G006: Earth Rotation Variations: Causes and Consequences

Variations in the rotation of the solid Earth are caused by processes
both external and internal to the solid Earth. The increasing accuracy
of the observations of the Earth's variable rotation provided by current
and next generation measurement systems allow smaller amplitude signals
to be observed, motivating improvements in both theories and models of
the Earth's rotation. The improved observations, theories, and models of
the Earth's rotation allow more accurate forecasts of the Earth's
rotation to be made, leading to more accurate tracking and navigation of
Earth orbiting and interplanetary spacecraft. This session will be a
forum for discussing the causes and consequences of variations in the
Earth's rotation.
