Description

The NCEDC DATALESS webservice gives access to instrument response information. The response information is returned in the
dataless SEED format.  The service can return responses for a channel, one or more channels under a location, or one or
more channels under a station.

The service can be easily invoked by using the unix curl and wget commands.


curl


$ curl -o BK.CMB.00.BHZ.ds "https://service.ncedc.org/ncedcws/dataless/1/query?net=BK&sta=CMB&loc=00&cha=BHZ"


This will send the request to the server and save the results in a file name BK.CMB.00.BHZ.ds


wget


$ wget -O BK.CMB.00.BHZ.ds "https://service.ncedc.org/ncedcws/dataless/1/query?net=BK&sta=CMB&loc=00&cha=BHZ"


This will send the request to the server and save the results in a file name BK.CMB.00.BHZ.ds

Make sure to surround the url with quotes or your unix shell will interpret the & characters as background control characters.

With recent versions of wget you can use the content-disposition flag to have the file saved to an automatic name.


$ wget --content-disposition "https://service.ncedc.org/ncedcws/dataless/1/query?net=BK&sta=CMB&loc=00&cha=BHZ"
