You are here: SZGRF Home / WWW Requests
This form allows requests to the continuous data archive of the SZGRF. Please see available data for available time spans of data streams.
Please fill the User Questionnaire to help us justifying our funding.
Please note: recently the instrumentation of the stations of the GRF array has changed. We replaced the STS-1 instruments by STS-2. The dates of the instrument change for the GRF station are listed below: GRA1 (10-May-2006), GRA2 (9-Oct-2006), GRA3 (11-Oct-2006), GRA4 (25-Sep-2006), GRB1 (14-Sep-2006), GRB2 (21-Jun-2006), GRB3 (19-Oct-2006), GRB4 (28-Sep-2006), GRB5 (7-Aug-2006), GRC1 (15-Mar-2005), GRC2 (9-May-2006), GRC3 (26-Jul-2006), GRC4 (19-Sep-2006).
New (since 6-Feb-2007): the HH channels (80Hz/100Hz data) are now available continuously and in near real time for many stations of the GRSN.
Please report publications using data of GRF or GRSN using this form or send mail to Klaus Stammler. We really need such responses for our funding.
Stations:
Selects station or station list for the requested
data. It is not possible to request GRF and GRSN together in one
file. You have to split your request in two, one for GRF and one for
GRSN. For reasons of simplicity not all station combinations are
available.
Components:
Select your components. This is
either only vertical 'z' or three components 'zne'. Please note that
not all of the GRF stations have three components.
Channel:
Sample rate of data. Available are 20Hz 'bh' for GRF and 20Hz and
1Hz ('bh' and 'lh', respectively) for GRSN. 'hh' data are available
after 4 - 8 weeks and only for 7 minute time windows of selected
events (see above).
Start time:
Start time(s) for copying data. Please use either the option buttons for day,
month, year, hour, minute and second to enter one start time or use the text
field for giving one or more (up to 30) start times. If using the text field
please mind the syntax (e.g. 23-may-98_8:28:20 or equivalently
23,5,98,8,28,20). Do not use any spaces within the time
string! In SEED and Mini-SEED requests only complete records are
copied. This means the data you get start a little earlier and end a
little later than your requested time window. You may specify a list of
up to 30 start times. If more than one start time is given the output files
(one for each time) are put into a separate directory.
Length in sec:
Number of seconds to copy. Ridiculous large numbers are rejected.
Output format:
Should be self-explainable.
User ID:
ID number for users with large requests. With such an ID number you are
allowed to submit requests with more than 30 time windows by supplying a file
containing the start times via your anonymous ftp server.
Submit:
After pressing this button the request is immediately started.
Please stay online and wait for the response. If data are
successfully copied an output file is created on our ftp-server. You
can transfer this file just by clicking on the ftp-address displayed.
You either will get a dialog box asking you for your local path and
filename or you get a text window with the data. In the latter case
just save the content (as 'source') to a file (this also works for
SEED data even if the text displayed looks a bit odd). In case that
you specified more than one copy time using the text field area the created
link will point to a directory which contains one data file per requested
start time.
If
you have any more questions please contact Klaus
Stammler.
