Using arclink data for SH's inventory
Using the script fetch_build_inventory.py (download) you can transfer the meta data information from arclink into the Seismic Handler's inventory. This script is located in recent installation in the directory $SH_UTIL/inventory.
Prerequisites
The script uses ObsPy. Please make sure that you have obspy.core and obspy.arclink installed.
Usage
Information is saved into STATINF.DAT, sensitivities.txt and filter_lookup.txt in /tmp/. You should check these files before you append the content to your regular input data in $SH_INPUTS. Then copy the transfer function files into $SH_FILTERS and start the creation of the simulation filters (see also simulation filters how-to).
Here's an example for GR.GRA1:
$ python fetch_build_inventory.py ======================================================================== Arclink Seismic Handler inventory tool ======================================================================== Your e-mail address for arclink query: walther@szgrf.bgr.de Please enter the network and station code. It may contain wildcards, e.g. 'EI.* for the whole irish network or 'GR.GRA1' for Graefenberg A1. Enter code: GR.GRA1 Fetched data for 1 stations. Fetched data for 9 channels. Saving station information to /tmp/STATINF.DAT... GR.GRA1 Saving sensitivity information to /tmp/sensitivities.txt... GR.GRA1..HHN GR.GRA1..LHN GR.GRA1..HHE GR.GRA1..BHZ GR.GRA1..LHE GR.GRA1..LHZ GR.GRA1..BHE GR.GRA1..HHZ GR.GRA1..BHN Saving filter information to /tmp/filter_lookup.txt... GR.GRA1..HHN GR.GRA1..LHN GR.GRA1..HHE GR.GRA1..BHZ GR.GRA1..LHE GR.GRA1..LHZ GR.GRA1..BHE GR.GRA1..HHZ GR.GRA1..BHN Now check the files in /tmp/. Afterwards append the information to the corresponding files in $SH_INPUTS. Alternatively configure additional input locations. Copy the transfer function files to $SH_FILTER. In order to create simulation filters (e.g. WWSSN-SP), run the following commands: $SH_UTIL/prep_simfilters.csh 3D842A $SH_UTIL/prep_simfilters.csh E6D9F0 $SH_UTIL/prep_simfilters.csh 3C01AF
You can also pass your email address and station code on command-line:
$ python fetch_build_inventory.py walther@szgrf.bgr.de gr.wet
You can fetch information for a whole network using wildcards like 'EI.*' (irish network).
Notes
- The script tries to create a minimum number of transfer functions.
- The names of the transfer functions are random generated but not necessarily unique. If you use this script several times, please check for conflicts before copying into $SH_FILTERS
- The script doesn't make use of wildcard options available in sensitivities.txt and filter_lookup.txt (e.g. GRA1-BH-?). So every channel is represented by one configuration line.
- Please enter a valid email address for arclink access to allow the data centers to monitor and improve their service.
