Description

SAC (Seismic Analysis Code) is a general purpose interactive program designed for the study of sequential signals, especially time series data. Emphasis has been placed on analysis tools used by research seismologists in the detailed study of seismic events. Analysis capabilities include general arithmetic operations, Fourier transforms, three spectral estimation techniques, IIR and FIR filtering, signal stacking, decimation, interpolation, correlation, and seismic phase picking. SAC also contains an extensive graphics capability.

For further background information, see SAC Availability for the IRIS Community, by Peter Goldstein and Arthur Snoke (Feature Article, IRIS DMS Newsletter, March 2005).

If you have technical questions about the SAC software, please send an e-mail message to the sac-help listserv. You must be a subscriber to post to this listserv. Read more.

You can also file tickets/issues or contribute to the wiki at the SAC project on SeisCode.
