[IGSMAIL-6221] Joint GGOS/IAU Science Workshop on Observing and Understanding Earth

[Gross, Richard S (335N)]

Author: Richard Gross
Subject: Joint GGOS/IAU Science Workshop on Observing and Understanding Earth

Dear Colleagues -

This is a reminder that the Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) and the International Astronomical Union (IAU) are jointly organizing a workshop on Observing and Understanding Earth Rotation that will be held in Shanghai, China during 25-28 October 2010. The program of the workshop is given below and more information about it can be obtained from the workshop web site at <http://202.127.24.12<http://202.127.24.12/>>.

On behalf of the organizers I would like to invite you to participate in this workshop. We are developing a rich program that will cover all aspects of the Earth's rotation including theory, measurement, analysis, excitation, and integration with other geodetic measurements into a global geodetic observing system. I hope that you will be able to join us in Shanghai for this exciting workshop.

Please note that the deadline for both registering and submitting abstracts is August 15, 2010.

Best regards,
Richard
