User interface boxes

The "Event Controls" box

Use this to select events to compose your request. This powerful tool is an event browser which can query several sources of information.

Catalog Services: At GFZ you can choose events from one of the following public catalog services:

  1. GFZ - The GEOFON catalog (http://geofon.gfz-potsdam.de/eqinfo/.)
  2. EMSC - The EMSC catalog (http://www.emsc-csem.org/Earthquake/.)
  3. USGS - The ANSS Comprehensive Catalog (ComCat) service (http://comcat.cr.usgs.gov/earthquakes/feed/v0.1/search.php.)
  4. XXXX NEIC - A temporary replacement for the NEIC service, at USGS (http://earthquake.usgs.gov/earthquakes/eqarchives/epic/) based on the new Comprehensive Catalog (ComCat). XXXX

Select "Catalog Services" under "Event Information". Then use the pull-down menu under "Catalog Service" to choose the desired catalog. Now you can filter events by:

  • Date interval
  • Magnitude range
  • Depth
  • Location

User Supplied: Alternatively you can upload your own catalog...

The "Station Controls" box

Use this to add channels to your request. The selection of stations can be made according to

  • by geographical coordinates
  • the currently selected events - distance and (back)azimuth are in degrees
  • or by network/station codes.

Symbols used on the pull-down lists are: * = temporary network; + = restricted access (see here)

You can limit the selection to particular types of streams/channels, either

  • by channel code, e.g. BH (for BHE, BHZ, BH1, etc). Note that location codes appear before the channel code. You can select multiple types of channel codes by selecting with the SHIFT and/or CTRL keys.
  • by sampling rate - for every station, this will return those streams with a reported sample rate closest to that specified.
The "Event and Station Map" box

Here the events and stations you choose will be displayed. Use the mouse to drag the map around. Use the left SHIFT + Mouse to drag areas for limiting the search of events and stations when the appropriate modules are enabled.

The "Event and Station List" box

The tables here show the events and stations you choose. Use these tables to check which events and stations have been selected by your search criteria. You can interactively remove unwanted items. Your final request will be built from the currently displayed information. You can refine the selection of streams for stations using the "Advanced Stream Filters Control".

Triangles on the column headers allow you to sort rows by the values in those columns.

The "O/R" column shows whether the station is "open" (field is empty) or "restricted" (shown by a red "R").

The "Submit" box

Use this to send your request to a server. You can check the status of your requests using the controls under the "Download data" tab.

The "Recent Requests" box

Here you can check the status of your Arclink requests made during your current use of this service. The usual request group operations (Reroute/Retry/Resend/Delete/Refresh) as well as download links are available on the status popup. Use this box to conveniently download a small number of recent data volumes.

The "Manage Requests" box

Here you can manage all your Arclink requests (including requests made during previous visits). Downloading all your data volumes with a single click is possible if you have jDownloader installed.

The "Console" box

Warnings and other messages appear here. Unwanted messages can be removed by reloading the page, or using the "Clear" button.
