Subject: 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
