A short introduction to the IRIS Data Management System
Data Holdings, Data Organization, and Data Access
• FDSN Backbone Network• 200 stations currently• Plans to increase in size to 300• Focus on real time data sharing

Data Sources
More than 16,152 seismic stations from >250 networks and 500 temporary deployments have
data available through the IRIS DMC
2,268 stations telemetered in real timefrom 98 different networks
2,361 Stations in SE Asia
201 SE Asian Stations come in real time to the IRIS DMC

Types of Sensor Data IRIS manages
IRIS Archive at 152 terabytes and growing at 27 terabytes per year
Data Request Tools at the IRIS DMC
Request Methods
• Routes user requests between data centers
• Wraps normal Data Center operations within an application layer
• Coordinates delivery of information back to a user
• Peer based system• Any NetDC node can act
as a hub data center• Or FDSN.ORG can be used

Real Time Data Flow from DMC
• Most of the 152 terabytes are in miniSEED format• Metadata has been provided in dataless SEED
format• The huge holdings are consistent and complete due
to adherence to FDSN standards• Data from
• >250 permanent seismic networks• ~500 temporary deployments• 16,152 stations• 2,249 stations in real time as of 2011
The IRIS Data Management Center
• Metadata workshops• Annual cycle• moving from SE Asia, Africa Middle East, Latin America
• Italy, Brazil, Malaysia, Egypt, Brazil, Thailand
• Regional Exchange of Earthquake Data (REED)• Focus on solving data communication issues
• Station to data center• Data center to Internet
• Past and current efforts• Central Asia• SW Pacific Tsunami Task Group• Africa
• Support for SeisComp-3• Configuration GUI, installation simplification, StationXML
Three International Activities Supported by IRIS DMS
• The IRIS DMS is available to all seismologists at the same priority level
• All data are open• There is no charge for any of IRIS services• Only one piece of software has limited
distribution• Antelope only available to Full IRIS Members• SAC available to almost all seismologists
