According to the standard procedure approved in 2014 by the FDSN, GEOSCOPE data are referenced with the Digital Object Identifier (DOI) of the network.
The GEOSCOPE DOI is doi:10.18715/GEOSCOPE.G
If you are using GEOSCOPE data for your research, this DOI has to be mentioned in the "Acknowledgments" or in a specific section ("Data resources", or similar) where data origin is requested. Rather than the DOI alone, we encourage the use of the full citation :
Institut de physique du globe de Paris (IPGP) and Ecole et Observatoire des Sciences de la Terre de Strasbourg (EOST). (1982). GEOSCOPE, French Global Network of broad band seismic stations. Institut de physique du globe de Paris (IPGP), Université de Paris. https://doi.org/10.18715/GEOSCOPE.G
According to FDSN guidelines, we also strongly encourage to cite the GEOSCOPE network in the main body of your paper (in particular when the study uses a small number of seismic networks). This is done as for a classic article citation :
In the main body of the article, for example :
In this study we used data from the GEOSCOPE network (Institut de physique du globe de Paris (IPGP) and Ecole et Observatoire des Sciences de la Terre de Strasbourg (EOST), 1982).
In the Reference list :
Institut de physique du globe de Paris (IPGP) and Ecole et Observatoire des Sciences de la Terre de Strasbourg (EOST). (1982). GEOSCOPE, French global network of broad band seismic stations. Institut de physique du globe de Paris (IPGP), Université de Paris. https://doi.org/10.18715/GEOSCOPE.G
The reference above can also be automatically generated using the FDSN web tool.
Some examples using arclink_fetch:
Principle : the user submit the request in a text file to an ArcLink server.
Get an inventory
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 * * *
Get data
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.
Get metadata
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
Some examples using the ObsPy library:
Script 1
This script retrieve data for the BH channels for the TAM station, and display the waveforms:
from obspy.core import UTCDateTime
from obspy.arclink.client import Client
client = Client(host='eida.ipgp.fr', port=18001, user=This email address is being protected from spambots. You need JavaScript enabled to view it.', debug=False) client.status_delay=3
t = UTCDateTime("2011-01-10 18:36:59")
st = client.getWaveform("G", "RER", "00", "BH*", t, t + 60 * 60)
st.plot()
