Webservice FDSN timeseriesplot

The timeseriesplot service returns a graphical representation of time series data of the RESIF seismic network. The time span may be up to 31 days. Only unrestricted data are available.

The service offers several options

Output format options

Detailed descriptions of each query parameter

Station code details

The four parameters (network, station, location, channel) determine channels of interest.

Parameters Examples Discussion
net[work] FR Seismic network name.
sta[tion] CIEL Station name.
loc[ation] 00 Location code. Use loc=-- for empty location codes.
cha[nnel] HHZ Channel Code.

Wildcards and Lists

For example, with channel codes: channel=EH?,BHZ

Date-range options

The definition of the time interval may take different forms:

Expressed as calendar dates

Parameters Examples Discussion
start[time] 2015-08-12T01:00:00 Start time expressed as a calendar date.
end[time] 2015-08-13T01:00:00 End time expressed as a calendar date.



Expressed as a calendar date and duration (seconds)

Parameters Examples Discussion
start[time] 2015-08-12T01:00:00 Start time expressed as a calendar date.
end[time] 7200 End time expressed as duration (seconds).



This example specifies a calendar date as the start time and duration of 7200 seconds specified in the end[time] parameter.

Expressed as a calendar date, duration (seconds) or the key word: “currentutcday”

The key word “currentutcday” means exactly midnight of today’s date (UTC time). It may be used for the start[time] and end[time] parameters.

Parameters Examples Discussion
start[time] 7200 Start time expressed as duration (seconds).
end[time] currentutcday Today’s midnight (UTC).


  1. …starttime=currentutcday&endtime=7200…
  2. …starttime=7200&endtime=currentutcday…

The first example specifies the duration of 2 hours after today’s midnight (UTC). The second example specifies the duration of 2 hours prior today’s midnight (UTC).

Time series processing options

The following parameters allow filtering the time series.

Parameters Examples Discussion Default value
demean true Remove the mean of the time series. false
true Apply instrumental correction by deconvolution with earth units conversion. false
waterlevel 10
Waterlevel (en dB) used for the deconvolution.
“none” value corresponds to the classical inverse filtering.
freqlimits 0.01-0.04-0.5-0.6 Band pass filter applied to the frequency domain prior to the deconvolution1,2. Rectangular window between f2 and f3 and cosine window between f1 and f2 and between f3 and f4. none
units VEL Output unit (AUTO, DISP, VEL, ACC). Enabled only with earthunits option. AUTO

Notes :

  1. Frequency in Hertz.

  2. Frequency numbers may be separated by a comma or by a dash. For example : 0.01,0.02 or 0.01-0.02
