Dear Colleagues

This is the final announcement of the planned GGFC workshop to be held in Vienna, 20-April at the Marritott Courtyard Vienna Messe. http://www.marriott.com/hotels/travel/viefg-courtyard-vienna-messe

Registration will begin at 8:30.

The Registration Fee for the meeting will be 75 euros. Sorry, but I can only accept cash.

The meeting will focus on assessing the errors in current environmental models and proposals for overcoming these limitations for use in geodetic and geophysical data analysis.

The following are the confirmed Invited speakers to date:

Maik Thomas	On the challenges of developing a mass conserving system model
Minkang Cheng	Degree 2 and geocenter variation from SLR
Xavier Collileux	Call for space geodetic solutions corrected for non-tidal atmospheric loading at the observation level
Thomas Hobiger	How to deal with coordinate systems in numerical weather models? - Goals of the newly formed IAG SSG12
Jim Ray	Consistency of crustal loading signals derived from models & GPS: Inferences for GPS positioning errors
Wei Chen	Evaluations of global geophysical fluid models based on broad-band geodetic excitations
Haoming Yan	Global mass balance effects on length-of-day change
Richard Gross	The GGFC Special Bureau for the Oceans: Providing Ocean Products for Geodesy
Brian Luzum	Global Geophysical Fluids: an IERS RS/PC Perspective
J.-P. Boy	High-resolution models of surface displacements caused by atmospheric, oceanic and hydrological loads
Rolf Dach	Mitigation of unmodelled non-tidal atmospheric pressure loading into parameters of a global GNSS solution
Erricos Pavlis	Tests of SLR products with and without the atmospheric loading and gravity variations
Johannes Boehm	Atmospheric effects in space geodesy - plans and perspectives
Wouter van der Wal	Uncertainties in models for glacial isostatic adjustment
David Salstein	Special Bureau for the Atmosphere status, and review of global atmospheric analyses and models, with application to geodetic uses
