The IRIS DMS consists of several components or "nodes" that work together to ensure the smooth flow of data from stations in the GSN, PASSCAL, FDSN, EarthScope, and other programs to the seismological research community.
Data Management System Nodes
The Components of the IRIS Data Management System
The IRIS DMS consists of eight distinct "nodes". The Albuquerque Seismic Laboratory (ASL) and the UCSD/IDA DCCs collect data from the GSN, perform QA on the data, convert the data to SEED and send the GSN data to the DMC.
The PASSCAL instrument Center (PIC) performs QA and reformatting for PASSCAL data. The Array Network Facility (ANF) is charged with insuring that USArray/Transportable Array data flow to the DMC and that proper metadata is available.
The Kazakh National Data Center (KZ) in Almaty performs QA on data from the numerous arrays and stations in Kazakhstan before forwarding the data to the IRIS DMC.
The University of Washington (UW) picks phases for all FARM data at the DMC and feedback any problems found. The DMC in Seattle is the home of the IRIS data archive and serves as the primary distribution point for IRIS data.
Governance and Staffing
The IRIS DMS is given oversight by a standing committee representing the seismological community. (See action items from DMSSC meetings.) The IRIS Data Management System is managed by Dr. Tim Ahern. Read about the charges to the DMS.
