Overview what is iris
Overview: What is IRIS? Center

  • Consortium of 103 US Universities

  • National Science Foundation Funded

    • $12.5 - $14.5 million per year

    • Significant EarthScope Funding

  • Four Programs

    • GSN

      • 138 permanent stations

    • PASSCAL

      • 4000 portable channels

    • E&O

      • Workshops, posters, museum displays

    • DMS

      • 5000 stations over 40 years

      • Archives 9 terabytes per year

      • Distributes 12 terabyte per year

      • Services 200,000 data requests per year

      • Will serve about 1 billion seismograms
