Thread: Data Request

Hi Ridho,

To request data from the Malaysian National Seismic Network (MY) I suggest using the IRIS FDSN web services https://service.iris.edu/fdsnws/. Alternatively you can make a BREQ_FAST https://ds.iris.edu/ds/nodes/dmc/manuals/breq_fast/ (FTP style) request. Below I’ve outlined some examples for you:

Requesting MY network metadata and waveform data:

Web Service Request:
FDSNWS Station web service https://service.iris.edu/fdsnws/station/1/ (Request channel level metadata for the MY network).
Example: https://service.iris.edu/fdsnws/station/1/query?network=MY&matchtimeseries=true&format=text&level=channel&nodata=404

FDSNWS Dataselect web service https://service.iris.edu/fdsnws/dataselect/1/ (Request yesterdays waveform data for network MY station IPM ).
Example: http://service.iris.edu/fdsnws/dataselect/1/query?network=MY&station=IPM&starttime=2018-04-19T00:00:00&endtime=2018-04-20T00:00:00&nodata=404

Note that for web service requests for large amounts of data it is best to use a dedicated request client:
https://service.iris.edu/clients/

BREQ_FAST Request:
You can use the following form to make a BREQ_FAST request:
http://ds.iris.edu/ds/nodes/dmc/forms/breqfast-request/

You will receive an email once you request is submitted, followed by a second email containing a link to download your data. You can view the status of your BREQ_FAST request here: https://ds.iris.edu/ds/nodes/dmc/data/recent-shipments/.

Other useful links:

The following MDA page shows station information (metadata) for the MY network:
http://ds.iris.edu/mda/MY

The following GMAP page shows a station map restricted to the area around Malaysia. Note that there are other networks/stations in the area, besides MY, that you may find useful.

The availability web service returns information about the actually data availability in the archive:
https://service.iris.edu/irisws/availability/1/

Thanks,

Nick

Hello, I'm Ridho from ITB. Now I'm doing the thesis on The Ambient Noise Tomography for Sumatera Island. So I need some of the waveform data from the stations located at Malaysia ( Malaysian National Seismic Network). How can I get it? Thank you

regards,
