Hans-Peter Plag has asked me to bring this workshop to your attention:

IGCP 565 Workshop 3: 
Separating Hydrological and Tectonic Signals in Geodetic Observations
Reno, Nevada, October 11-13, 2010

The Third Workshop in the sequence of five annual workshops organized by the IGCP 565 Project will be held on October 11-13, 2010 in Reno, Nevada, USA. This workshop is jointly organized by the IGCP 565 Project, the Group on Earth Observations (GEO), the Global Geodetic Observing System (GGOS), and the Nevada Bureau of Mines and Geology (NBMG) and the Nevada Geodetic Laboratory (NGL) at the University of Nevada, Reno (UNR).

The focus of this workshop will be on the separation of hydrological and tectonic signals in geodetic observations of time variable Earth's gravity field, surface displacements, and rotation. 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 improved data on water storage changes. In order to fully utilize the potential of geodetic observations to provide estimates of land water storage changes in these regions, the tectonic and hydrological signals need to be separated.

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