ADVANCES IN DATA DISTRIBUTION SYSTEMS, HIGH LEVEL PRODUCT GENERATION, AND THE MEASUREMENT OF DATA QUALITY METRICS AT THE IRIS DATA MANAGEMENT CENTER

The IRIS Data Management Center (DMC) manages the largest concentration of broadband seismological data in the world. DMC data and services are free and open. A rich variety of request tools are currently being extended using Representational State Transfer (REST) web services. These new methods of providing access to data will greatly simplify a research or monitoring group’s ability to retrieve information quickly, reliably, and in a form that is readily usable. In addition to raw time series data, the IRIS DMC is developing higher-order products intended to raise the level from which subsequent research begins. These products include such things as ground motion visualizations, a variety of event plot displays, synthetic seismograms, management of tomographic models along with visualization tools, GCMTs, calibration information, and receiver functions. These products are available through web services from the IRIS DMC’s new product management system, SPUD. A final project, being built using web services, is an entirely new implementation of the IRIS DMC’s quality assurance system, QUACK. The new system will use web services in a manner that allows attributes of data quality for any time series channel (seismic, infrasound, hydro acoustic, etc) to be calculated. The modular system will include several improvements over the existing system, providing better scalability, flexibility, and usability. This poster provides an overview of these new services (data access, products, and quality metrics) to the researchcommunity.
