FDSN Working Group IIData Exchange and Data Centers By Bernard Dost, ORFEUS Data Centre, deBilt Netherland Tim Ahern FDSN Data Center for Continuous Data IRIS Data Management Center 9 November, 2006 FDSN Regional Assembly 2006 ASC Meeting Bangkok, Thailand
Goal of FDSN WG II • To coordinate data exchange between • Data center to data center • Data center to data users
Achievements/Topics • Definition of the SEED format • FDSN provides Network codes • Discussion and coordination of data exchange procedures • Request mechanisms • Email based (e.g. autoDRM, BreqFAST,NetDC) • Web based (e.g. Wilber II, WebDC) • API based (e.g. jWeed, VASE) • Data exchange procedures • E.g. Seedlink/ArcLink, Data handling Interace (DHI), Ninja • Discussion on standardization of data exchange for other data • Synthetic seismogram data (special group)
Achievements/Topics-2 • Software developments • Reference SEED reader (rdseed) • use of Java and XML requires coordination of Java class definitions and XML definitions • FDSN archive • IRIS DMC (global - FDSN back-bone network) • ORFEUS DC (regional) • Quality Control • Station book
FDSN Data Center for Continuous Data at the IRIS DMC • Available Data • Real Time Data • FDSN Goals wrt Data • Virtual Networks • Data Usage
Data from 1966 -Present Temporary • Targets of Opportunity • 1966 - current • Unstructured Data • Apollo • Temporary Experiments • 1986 - current • Permanent Networks • 1970 - current Targets of Opportunity Permanent Networks
More than 5,000 seismic stations have data available through the FDSN Archive
