French Global Network of broad band seismic stations
The GEOSCOPE Observatory is a Global Network of Broad Band Seismic Stations.
These stations are recording continuously the ground motion. Data of most of the stations are arriving in real-time to the IPGP Data Center and are archived after validation.
The GEOSCOPE Observatory provides data and informations for earthquakes with magnitudes larger than 5.5-6. Similar information may be provided for smaller earthquakes, for example those located in France or in the European-Mediterranean region.

Some examples using arclink_fetch:
Principle : the user submit the request in a text file to an ArcLink server.
With the following example you get an inventory of the data available on the arclink server.
The file (request1.txt), covered the period from 1990 to 2012, for all the networks, stations, channels:
1990,1,1,0,0,0 2012,12,31,0,0,0 * * * *
Run the command line :
$ arclink_fetch -a eida.ipgp.fr:18001 -k inv -v -u This email address is being protected from spambots. You need JavaScript enabled to view it. -o inventaire.xml request1.txt
arclink_fetch send the file « inventory.xml ». This file contains all the networks, stations and channels available.
You can limited the inventory to a single network. Here is an example for the G network:
1990,1,1,0,0,0 2012,12,31,0,0,0 G * * *
With the request file (request2.txt) you can get data in miniseed format for the BHZ channel of the TAM station of the G network:
2011,01,01,00,00,00 2011,01,04,00,00,00 G TAM BHZ *
$ arclink_fetch -a eida.ipgp.fr:18001 -k mseed -v -u This email address is being protected from spambots. You need JavaScript enabled to view it. -o tam.mseed request2.txt
The file tam.mseed will be created on your computer.
In the following example you will get a dataless file for the TAM station of the G network::
$ arclink_fetch -a eida.ipgp.fr:18001 -k dseed -v -u This email address is being protected from spambots. You need JavaScript enabled to view it. -o tam.dataless request2.txt
You can read the dataless file with the rdseed software:
$ rdseed sf ./cgpb.dataless
