Dear members of the FDSN WG III on Products

You are receiving this email because you are a member of FDSN Working
Group III on Products.
If you wish to have your email address removed, you can request this
yourself at the following location
http://norman.iris.washington.edu/mailman/listinfo/fdsn-wg3-products
where a variety of options are available.

At the last FDSN meeting in Perugia, this group was formed and we
took some initial first steps.

We identified that we should attempt to have FDSN networks produce
Probability Density Functions (PDF) images of Power Spectral Density
(PSD) measurements. We selected
this as the first FDSN product since freely available software to
produce the PDF plots exist. The PQLX
software has been written by Richard Boaz with primary support from
the USGS, IRIS PASSCAL and the IRIS
Data Management System. The PDFs are also very useful products that
help estimate the quality of a seismic station.

A recent article in the ORFEUS Newsletter describes the PQLX software,
what it does and where users
can download it. Please refer to
www.orfeus-eu.org/Organization/Newsletter/vol8no1/PQLX/PQLX.htm
for more information.

The next FDSN meeting will be held in conjunction with the IASPEI
meeting in Capetown, South Africa. The WG III
meeting is presently scheduled to take place on Tuesday January 13,
2009.

I am writing to you to determine if you will be able to participate in
the installation of the PQLX software and
the generation of the PDF plots for stations in your network. We
still have more than 6 months until the meeting and
this would allow for some statistically significant results to be
generated.

I would appreciate it if each of you can answer this email and let me
know your intentions with respect to
the generation of this first FDSN Data Product. I know that some of
you are already doing this at your centers but
your response is still requested. Please let me know what networks
and/or stations you will be generating
the PDF's for.

I look forward to hearing from you.

Best Wishes

    Dear all,

    Recently the PQLX software has been installed at ORFEUS Data Center
    ( http://www.orfeus-eu.org ) to produce PDF's ( http://www.orfeus-eu.org/cgi-bin/pqlx.cgi )
    for (almost) all stations in the Virtual European Broadband Seismograph Network (VEBSN)
    ( http://www.orfeus-eu.org/Data-info/vebsn.html ). The VEBSN is the pool of BB
    stations that presently includes stations from the following networks:


    AI - Antarctic Seismographic Argentinean Italian Network
    BE - Belgian Seismic Network
    BN - UK-Net, Blacknest Array
    BS - National Network of Bulgaria
    BW - BayernNetz, Germany

    Dear all,

    the present situation at GFZ is that PQLX is installed and operating in
    testing mode, but no web page yet. We have also almost all VEBSN
    networks from Reinoud's list plus some non-public European stations and
    many non-European RT networks. However, we are not permanently archiving
    and distributing (and therefore also not calulating PDFs for) those
    networks, where the primary responsibility is somewhere else (at ODC,
    INGV, IPGP or IRIS DMC). In addition, we will in future apply PQLX to
    our comprehensive temporary network archive.

    For explanation of the general situation in Europe let me add that we
    are presently establishing the EIDA, the European Integrated Data
    Archive, with ODC, INGV, IPGP and GFZ as primary nodes and hopefully a
    set of individual network data centers as secondary nodes. IPGP and
    INGV, as it looks now, will be responsible for the archives of
    GEOSCOPE/MedNet plus their different national networks while ODC and GFZ
    share primary responsibility for about half of the other European
    networks each. In addition, GFZ archives a number of RT networks from
    outside of Europe such as NU - Nicaragua, CX - N. Chile, AF - South
    Africa and IA - Indonesia, certainly more in future. For all of those
    networks PQLX products will be available soon.

    Regards,

    Winfried

    dear all,
    Since January 2007, daily noise PDF are computed
    for channels BH and LH of every GEOSCOPE stations
    using our own software.
    Noise level are computed at date day+8 for real time data
    and whenever data are archived for the other stations.
    Noise PDF are accessible on GEOSCOPE web site
    geoscope.ipgp.jussieu.fr -> stations -> noise level
    We are not planning for the moment to install pqlx
    at GEOSCOPE data center.
