The Advanced Research Projects Agency ARPA has been tasked by the Administration to prototype a Comprehensive Test Ban Treaty CTBT International Data Center IDC - a central element of the proposed CTBT verification regime. The IDC would support and make more affordable the verification responsibilities of States Parties by performing the computationally intensive tasks necessary for effective, global monitoring. The IDC would collect and archive large volumes of data from hundreds of worldwide seismic, radionuclide, hydroacoustic and infrasound sensor sites of the CTBT International Monitoring System IMS. Analyses, performed both by automated systems and human experts, would rapidly reduce this large volume of data by computing key parameters that estimate the existence, location and character of detected events. In the US model, the IDC would stop short of providing a formal identification of these events. However, all States Parties would have open and convenient access to all raw data and IDC products, with customized interfaces that allow interested States Parties to apply national criteria to screen for the subsets of data of interest to them. To meet the requirements for a CTBT IDC, ARPA, together with an international team of developers and operators, is expanding the framework of the Center for Monitoring Research, with an increased focus on data authentication, automated fusion of multi-sensor data, regional knowledge acquisition, reliable and secure distributed processing on UNIX systems, advanced data management technologies, effective data visualization and access, and an open and modular system architecture. The still-evolving prototype IDC is the centerpiece of an on-going Group of Scientific Experts seismic monitoring experiment called GSETT-3 that began full-scale operations in January 1995.
