************************************************************************ IERS Message No. 93 August 29, 2006 ************************************************************************ Fall AGU Earth Rotation Session Dear Colleague, Daniel Gambis, David Salstein, and I are convening a special session at the Fall AGU 2006 meeting on Earth Rotation/Polar Motion at Rapid Timescales. If you (or a colleague that you know) were planning on attending the Fall AGU and would like to inform your fellow colleagues on your research in this exciting field of study, please consider submitting an abstract to special session G13: Earth Rotation/Polar Motion at Rapid Timescales. You should submit your abstract through the website: , by the deadline, 7 September 2006 2359 UT (that is UT not EDT). I look forward to seeing you in San Francisco, this December. Sincerely, Thomas Johnson G13: Earth Rotation/Polar Motion at Rapid Timescales There have been efforts recently to concentrate attention on Earth rotation signals at high time resolution. Given current abilities in space-geodesy, observations of Earth rotation/polar motion are being made on daily and higher temporal resolution, especially as the subject of special campaigns. With current capabilities, interesting features can be detected in the Earth orientation and pole path from these observations with finer resolution than were possible earlier. The mechanisms that are causing such fluctuations may be a response to forcing by the geophysical fluids, and so information about the excitation of Earth orientation, by the atmosphere, ocean, cryosphere, and hydrosphere, at these timescales is also sought here. Relevant geophysical observations may be both in-situ and remotely sensed, and often combined through sophisticated models and data assimilation schemes. We wish to focus here on Earth orientation and its excitation on timescales up to a year. In addition, the ability to forecast the various signals in Earth rotation/polar motion at these timescales is of current interest, and such information is welcome in this session.
