SCEDC Availability Web Service



The SCEDC availability web service returns time span information of what timeseries are available at the SCEDC archive. It implements the /extent service query method. It produces lists of available time extents(earliest to latest) for selected channels (network, station, channel,location) and time ranges. Availability information is refreshed once a day in the backend.
At this stage, following data are availabile for queries:
  • triggered records from Jan 1977 - present
  • continuous records from Oct 1999 - Jan 2015
