Subject: No 0666 : Joint IGCP 565 Project/GEO/GGOS Workshop on Separating  
Hydrological and Tectonic Signals in Geodetic Observations

Dear Colleagues,

On behalf of the Program Committee, we would like to invite you to  
participate in an upcoming workshop on the separation of hydrological  
and tectonic signals in geodetic observations. This workshop, the  
third in a series of five, is jointly organized by the UNESCO  
International Geoscience Programme (IGCP) 565 Project, the Group on  
Earth Observations (GEO), the Global Geodetic Observing System (GGOS),  
and the Nevada Bureau of Mines and Geology and the Nevada Geodetic  
Laboratory at the University of Nevada, Reno (UNR). The workshop will  
be held on October 11-13, 2010 in Reno, Nevada, USA. More information  
on the workshop is available at  
http://www.igcp565.org/workshops/Reno_2010.

In regions like the Southwestern U.S., the Mediterranean, Northern  
India, East Africa, and large parts of East Asia, tectonic processes  
and changes in land water storage produce overlapping signals in  
geodetic observations. At the same time, these regions experience  
water scarcity and would benefit from improved water management  
informed by additional data on water storage changes. Geodetic  
observations of time-variable gravity, surface displacements, and  
rotation potentially can be used to estimate changes in land water  
storage. In order to fully utilize this potential, the tectonic and  
hydrologic signals need to be separated, evaluated, and tested.

The Workshop aims to bring together experts in the relevant fields  
including geodesy, tectonics, hydrology, and hydrometeorology for a  
review of the current state of knowledge with respect to the geodetic  
fingerprints of the tectonic and hydrologic processes and recent  
change. A primary goal is to identify the main challenges in modeling  
and separating the various contributions, and to make progress towards  
an agenda that address these challenges through focused research  
projects.

Together with a number of colleagues active in hydrology,  
hydrometeorology, tectonics, and geodesy, we are currently developing  
a diverse, comprehensive and exciting program covering the  
characteristics of the relevant hydrologic and tectonic processes, the  
state of the art in predicting geodetic fingerprints due to these  
processes, the current capability to separate these signals in  
geodetic observations, and case studies in selected regions. We hope  
that you will be able to join us in Reno for this timely and exciting  
workshop.

Best regards

Norman Miller and Hans-Peter Plag
