Thread: data of waveform

Hi Fateme,

Below I’ve outlined what I believe would be the best approach for requesting this data.

Step 1: Determine what stations you want to request:

Using GMAP you can determine what stations are available near both Turkey, Armenia, and Azerbaijan. Below I’ve included a few examples for you, but feel free to modify the parameters in the program to meet your needs. Note I have specified a date filter to restrict your results to stations that are currently active.

Turkey, Armenia, and Azerbaijan geographic boundary: https://ds.iris.edu/gmap/#starttime=2018-05-25&maxlat=43.4125&maxlon=51.2292&minlat=35.5226&minlon=25.0378&drawingmode=box&planet=earth
KO (Turkey Network): https://ds.iris.edu/gmap/#network=KO&starttime=2018-05-25&planet=earth

Step 2: Use IRIS FetchData to request station metadata and time series data:

Once you determine what stations you would like to request data for, you can use FetchData https://seiscode.iris.washington.edu/attachments/download/1270/FetchData-2017.164 to download the data for your stations.

Fetch scripts download page: https://seiscode.iris.washington.edu/projects/ws-fetch-scripts/wiki
Fetch scripts tutorial: https://seiscode.iris.washington.edu/projects/ws-fetch-scripts/wiki/Running_the_scripts_and_examples

This is the preferred method for requesting data since it supports seamlessly requesting data across multiple data centers by utilizing the IRIS FedCatalog web service https://service.iris.edu/irisws/fedcatalog/1/. This is important for requesting data in this geographic area, as much of it is at datacenters other than the IRISDMC (such as KOERI http://www.koeri.boun.edu.tr/new/en and ORFEUS https://www.orfeus-eu.org/). An example of how to make a federated request using the fetch scripts may be found here https://seiscode.iris.washington.edu/projects/ws-fetch-scripts/wiki/Running_the_scripts_and_examples#Requesting-data-from-multiple-data-centers-federated. I’ve also outlined a federated FetchData example for two stations in the KO network below. Notice how data is fetched from the KOERI network.

e.g.

| => ./FetchData-2017.017 -F -N KO -S KARS,AGRI -s 2018-05-24T00:00:00.0 -e 2018-05-25T00:00:00.0 -o KO.2018-05-24.mseed -m KO.2018-05-24.meta
Received 367 Bytes from federator catalog in 0.2 seconds (2.3 KB/s)
Fetching data from KOERI (http://www.koeri.boun.edu.tr/2/tr)
Received 245 Bytes of metadata in 0.4 seconds (583 Bytes/s)
Processed metadata for 3 channel epochs in 0.4 seconds
Received 38.5 MB of time series data in 10.7 seconds (3.6 MB/s) - written to KOERI-KO.2018-05-24.mseed
Writing metadata (3 channel epochs) to file: KOERI-KO.2018-05-24.meta
DONE at 2018-05-25 17:18:23

Best,

Nick
