Project Abstract
 The goal of the CGM project is to develop spatially and temporally dense time series of ongoing defor- mation that provide unique input for addressing the fundamental problems of earthquake physics target- ed by the SCEC community. The CGM draws upon expanded Global Positioning System (GPS) cover- age, new SAR missions, and maturing data analysis techniques that leverage the complimentary fea- tures of both data types. By adopting a community-driven approach, we bring together the kind of broad expertise and diverse perspectives needed to explore the effect of modeling choices and provide a win- dow into the scope of epistemic uncertainty.
Intellectual Merit The CGM effort is leading to more rigorous joint use of GPS and InSAR data for a variety of applications that are central to SCEC’s mission including the quantification of crustal strain rates, interseismic fault locking, and fault- related transient deformation. The project has spurred efforts within the geodetic community to work together in developing best practices for fully utilizing the wealth of existing and newly available geodetic data.
Broader Impacts The further development of analysis techniques and evaluation of geodetic data products being carried out by the CGM group not only are providing more robust and precise geodetic data sets and models for southern California but are more generally applicable to the combined use of GPS and InSAR data internationally. This is especially important given the new SAR satellites that several countries have recently launched and/or are planning.
