Scripps Orbit and Permanent Array Center, Scripps Institution of Oceanography
Data Center Description
The Scripps Orbit and Permanent Array Center (SOPAC) is located at the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics (IGPP), Scripps Institution of Oceanography (SIO), University of California, San Diego (UCSD) in La Jolla, California. SOPAC's primary scientific role is to support high precision geodetic and geophysical measurements using Global Positioning System (GPS) satellites, particularly for the study of earthquake hazards, tectonic plate motion, plate boundary deformation, and meteorological processes. SOPAC investigators also conduct research on the implementation, operation and scientific applications of continuously monitoring GPS arrays and Synthetic Aperture Radar (SAR) interferometry.
SOPAC is a major participant in the International GPS Service (IGS), serving as a Global Data Center and a Global Analysis Center. SOPAC is the archive for the 250-station Southern California Integrated GPS Network (SCIGN), as well as an analysis center and a data retrieval facility. SOPAC maintains an archive of regional continuous GPS data for UNAVCO, Inc. focusing on the Western North America plate boundary and is developing a seamless archive interface for UNAVCO. SOPAC performs research and provides operational support for NOAA's Forecast Systems Laboratory (FSL) real-time GPS meteorology project for short-term weather forecasting. SOPAC also provides essential infrastructure support for the California Spatial Reference Center (CSRC), a partnership with the National Geodetic Survey (NGS).
