The following products are in the f — Funded category (8):
Do-it-yourself automated surface wave tomography using the MATLAB based ASWMS package developed by Ge Jin & James Gaherty. This product provides 1) the ASWMS software package and 2) weekly updated USArray, Alaska surface wave tomography maps using ASWMS.
The shear-wave splitting (SWS) databases data product provides the geosciences community with an easy access to two published databases:
Earthquake energy and rupture durations are estimated following all earthquakes with initial magnitude above Mw 6.0 and a GCMT moment tensor. The method follows Convers and Newman, 2011. These are fully automated and not reviewed by a human.
An ambient noise cross-correlation based database of empirical Green's functions (EGFs) of the Western US using USArray Transportable Array (TA) data.
A nested global empirical Green’s tensor (EGT) database derived from three-component continuous data at global, continental and local length scales.
The database is intended to be an open database for anyone to contribute as long as data processing follows a consistent, best practice.
USArray magnetotelluric transfer functions calculated from USArray MT stations by Oregon State University are available from the SPUD EMTF repository in both XML and EDI format and also directly from the DMC’s website in the EDI format.
An XML format for electromagnetic transfer functions and related conversion software was developed by OSU with funding from IRIS. The software and documentation is available in the SeisCode EMTF-FCU project.
The SeisSound Visualization is an audio/video-based IRIS DMC data product that illustrates the frequency and amplitude content of seismograms. Conveying the seismograms frequency content both visually and audibly produces a better understanding of their spectral content.
EMERALD is a complete open-source software server-based system for requesting and processing large sets of event based seismic data from a web browser. Data sets containing millions of seismic waveforms can easily be managed, reviewed, and processed. The system can automatically check for metadata updates, and alert the user to metadata changes.
IRIS DMC has been
certified as a trusted repository
