Orfeus data center
ORFEUS Data Center – mission
The primary purpose of the ORFEUS Data Center (ODC) is to collect and archive high quality seismic broadband waveform data from European and Mediterranean organizations, and to give open and rapid access to the data by the scientific community.
The ODC can fulfill this mission only in strong cooperation with seismic observatories, seismic network operators and end users from the scientific community.

Vebsn - data
Data-flowover 1650 channels flowing in per day resulting in a “size per day”
of around 7 Gb
mainly slink2orb and orb2orb
Frequency-rangeranging from very broad band (0.1 Hz) up to high frequency
channels (125 Hz)
Additional sensor30 accelerometric stations (120 Hz) from the Swiss network

QC – PQLX
Old situationcalculations on all incoming traces. Currently 1 day takes approximately 10
hours (1 cpu)
New situationnew 4 quad core server, running pqlx on 8 cpu’s I day takes
approximately 1-1.5 hoursbackwards calculations for archive data 2010, currently somewhere in
2006.
