Instrument Response Requests
Requesting Instrument Response Files
There are several stratagies for downloading instrument response files and deconvolving instrument responses from the data.
Response files can be downloaded as:
-
dataless files
-
RESP files
-
SAC poles and zeroes
-
part of the full SEED volume
-
files from the IRIS MetaData Aggregator page
Dataless files
-
Generate a request for a dataless using the DMC SeismiQuery tool
-
Submit a BREQ_FAST style request to dataless@iris.washington.edu from your mail client
-
Get a dataless from the BUD Query Interface
-
Download network dataless SEED files from the IRIS ftp site: http://ftp.iris.washington.edu/pub/RESPONSES/DATALESS_SEEDS/
RESP files
-
Response can be downloaded using the DMC SeismiQuery tool
Response can be downloaded using the webservices tools
-
Go to http://www.iris.edu/SeismiQuery/
Go to http://service.iris.edu/irisws/resp/1/
-
Choose the ‘responses’ button on the hint bar on the lower portion of the page
-
Fill out the information for your desired network ID and channels and then hit “View Results”
-
A listing of stations and channels will appear, check to see if its correct
-
Choose the “RESP file” checkbox at the top of the page
-
Hit the “Submit” button to submit your request.
-
You will receive an email confirming your request
-
When the response files are available, you will receive another email with instructions on how to download them.
SAC poles and zeroes
-
Use Breq_fast, NetDC, SeismyQuery, WebRequest, Wilbur3, or SOD to download a SEED volume
-
Use the rdseed tool to write out RESP file:
-
This can be done by specifying the -p option when using the command line execution
-
If using the User Prompt Mode, choose 'Y' when asked to "Output poles and zeroes?[Y/(n)]:"
For more information and examples, go to the rdseed manual: http://www.iris.edu/dms/nodes/dmc/manuals/rdseed/
SEED volume
-
Use Breq_fast, NetDC, SeismyQuery, WebRequest, Wilbur3, or SOD to download a SEED volume
-
Use the rdseed tool to write out RESP file:
This can be done by specifying the -R option when using the command line execution
If using the User Prompt Mode, choose 'Y' when asked to "Extract Responses [Y/(N)]"
For more information and examples, go to the rdseed manual: http://www.iris.edu/dms/nodes/dmc/manuals/rdseed/
From IRIS MetaData Aggregator website page
-
From the MetaData Aggregator website page choose a network from the available list (ex. 7D Cascadia)
-
Choose a station (ex. FS01B)
-
Choose a channel (ex. HH1)
-
On the page will be a link to "View resp", click on the link
-
Copy and save the response file
Once downloaded the files can be viewed and deconvolved from files using several tools:
-
evalresp
http://www.iris.edu/dms/nodes/dmc/manuals/evalresp/
-
remove instrument response directly from data using web services using FetchData
http://service.iris.edu/clients/
-
SAC
