  3. What must CORS West be able to handle? • Collect and Process CORS data • Distribute CORS data to the public • Share work load with primary CORS facility in Silver Spring

  4. Current Capabilities in Boulder • CORS Data Archive (1994-present) • Replicated NGS Database • Data Collection and Processing of 300 sites • Data Distribution via Anonymous FTP (ftp://wwwest.ngs.noaa.gov) • Archive Backups of all CORS data (NGDC)
