Welcome to the SOPAC, CSRC and MEaSUREs website
The Scripps Orbit and Permanent Array Center (SOPAC) has redesigned its web pages (formerly http://sopac.ucsd.edu) and merged them with the redesigned California Spatial Reference Center (CSRC) Web pages (formerly http://csrc.ucsd.edu). New to this collection is MEaSUREs (Making Earth System Data Records for Use in Research Environments), a collaborative NASA program with the Jet Propulsion Laboratory (JPL).
The three entry points under a single unified Web structure:
|CSRC homepage||MEaSUREs homepage|
We have organized the Web pages horizontally as a series of main headers, each linked to a series of vertical subheaders.
Information specific to each of the centers is located under the main headers “SOPAC”, “CSRC” and "MEaSUREs."
The SOPAC data archive is common to all programs so we’ve created a single main header “Data Archive.” Similarly, all applications are organized under one main header “Applications.”
We’ve created a single main header, “CRTN” for the California Real Time Network.
The “Maps” main header contains a new Google maps interface for the California Spatial Reference Network (CSRN), and for CRTN. It also contains access to our legacy map pages accessed through GPS Explorer.
The main header “Contact Us” reflects the overlap of SOPAC and CSRC personnel and indicates the primary contacts for each center and individual.

Update August 30, 2019: July 4,6 2019 Ridgecrest earthquakes
SOPAC computed coseismic offsets using the GAMIT/GLOBK software with 30s data from 98 continuous GNSS stations that experienced total displacements greater than 3 mm.
