IRIS DMC MUSTANG noise-mode-timeseries Web Service Documentation


The noise-mode-timeseries web service returns Probability Density Function daily mode estimates for individual seismic channels measured at discrete frequencies as a function of time.

Below is a full list of service parameters and their usage.

Date and Time Formats

Year, Month, Day in Month — Time:

YYYY-MM-DDThh:mm:ss[.ssssss] ex. 1997-01-31T12:04:32.123

YYYY-MM-DD ex. 1997-01-31 a time of 00:00:00 is assumed


YYYY	:: four-digit year
MM	:: two-digit month (01=January, etc.)
DD	:: two-digit day of month (01 through 31)
T	:: date-time separator
hh	:: two digits of hour (00 through 23) (AM/PM NOT allowed)
mm	:: two digits of minute (00 through 59)
ss	:: two digits of second (00 through 59)
ssssss	:: one to six digits representing decimal fractions of a second, down to microseconds

Requests that return no result

By default, FDSN services return an HTTP code of 204 when a request is “successful”, but there were no matching results. This behavior allows automated systems to know the difference between a successful request (with no data) from an incorrect request (bad parameter names, invalid URL, etc). Since no content is returned, the page on the web browser will not change. To force the service to return a 404, add the query parameter nodata=404.
