IRIS Data Brick

Using the IRIS Data Brick at the workshop.

Many of the common FDSN web service clients allow setting the specific service locations. For this workshop the service is at:

http://10.200.65.174:8080/fdsnws/dataselect/1 (IP likely changing each day, updates will be posted) or http://iris-dbserver.local:8080/fdsnws/dataselect/1 (.local not consistently working)

What is on the data brick? Use the ‘summary’ endpoint:

http://10.200.65.174:8080/fdsnws/dataselect/1/summary

Using with ObsPy

 from obspy.clients.fdsn import Client
 client = Client("IRIS", service_mappings={
      'dataselect': 'http://10.200.65.174:8080/fdsnws/dataselect/1'})

Using with FetchData

$ FetchData -timeseriesws http://10.200.65.174:8080/fdsnws/dataselect/1

-p pReserved

   srun -N4 -p pReserved myjob
   sbatch -p pReserved jobscript

List all jobs:
