The program of the workshop is given below and more information about it can be obtained from the workshop web site at <<a href="http://202.127.24.12/">http://202.127.24.12</a>>.<br><br>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.</div><div><br></div><div>Please note that the deadline for both registering and submitting abstracts is August 15, 2010.</div><div><br></div><div>Best regards,</div><div>Richard<br><br>..........................................................<br><br>Joint GGOS / IAU Workshop<br><br>Observing and Understanding Earth Rotation<br><br>October 25–28, 2010; Shanghai, China<br><br>Session 1: Introduction<br>Conveners: Richard Gross, Harald Schuh, Cheng-li Huang<br> Welcome / Workshop Goals<br> Overview of GGOS<br> Importance of reference frames and the EOPs connecting them to GGOS<br> Overview of IAU Commission 19<br> Overview of SHAO<br><br>Session 2: Earth Rotation Measurement Techniques<br>Conveners: Harald Schuh and Cheng-li Huang<br> Conventional techniques (VLBI, GNSS, LLR, SLR, DORIS)<br> Emerging techniques (ring laser gyroscope, etc.)<br> Development of near real-time measurement systems<br> Global networks of integrated systems<br><br>Session 3: Earth Rotation Analysis and Prediction<br>Conveners: Jianli Chen and Richard Gross<br> Theory of Earth rotation variations<br> Characteristics of observed variations<br> Techniques of analyzing observed variations<br> Combining past observations and predicting their future evolution<br><br>Session 4: Excitation by Surface Geophysical Fluids<br>Conveners: Jolanta Nastula and Shuanggen Jin<br> Overview of atmosphere, ocean, and hydrology models<br> Atmosphere and climate change<br> Oceans and sea level change<br> Hydrology and ice mass change<br> Tides (atmosphere, ocean, solid body) and tidal friction<br><br>Session 5: Excitation by Non-Fluid Processes<br>Conveners: Richard Gross and Ben Chao<br> Earthquakes<br> Glacial isostatic adjustment<br> Core-mantle interactions<br><br>Session 6: Integrating Earth Rotation, Gravity, and Shape Measurements into a Global<br> Geodetic Observing System<br>Conveners: Hans-Peter Plag and Jianli Chen<br> Relationship between Earth rotation, gravity, and shape variations<br> Joint inversion of rotation, gravity, and shape measurements for surface mass loads<br><br>...........................................................</div></body></html>
