Data products derived from raw data are produced both by the scientific community and the IRIS DMC. These complement the simple data products based on raw data such as event segmented waveforms, which are available via the DMCs traditional data access mechanisms. Community guidance is for our product development efforts is provided by the Data Products Working Group; feedback, suggestions and input are welcome at any time.
Below is a list of products produced either at the DMC or by the research community that are available from the DMC. Many of these products are available in SPUD where you can easily search for and download products.
What is coming next? Check the product development list.

EMC - Earth Model Collaboration
A repository of Earth models with the aim of providing the research community with access to various tomographic models, visualization tools for model preview, facilities to extract model data/metadata and access to the contributed processing software and scripts.

GMV - USArray Ground Motion Visualizations
Visualizations of real data showing how seismic waves sweep across the USArray network of seismic stations. Watch how seismic waves from earthquakes in the US and around the world cause the ground to move at each seismometer.Create customized GMVs
A comprehensive suite of station maps, record sections, vespagrams and coda stacks generated shortly after events using all available, three component broadband data at the IRIS DMC for earthquakes larger than magnitude 6.0.
The Back-projection product shows the beamformed time history and location of coherent short period P-wave energy generated by all modern large M6.5+ earthquakes observed at three regional arrays and across the Global Seismic Network.
Global ShakeMovie Synthetics
The IRIS DMC archives and distributes synthetic seismograms from the Global ShakeMovie project at Princeton University calculated for all GCMT events in near real-time. 1D normal mode and 3D SPECFEM synthetics are available.
TA Infrasound Reference Event Database (TAIRED) & Detections (TAID)
SeisSound, the Audio/Video Seismic Waveform Visualization
SWS-DB - Shear-Wave Splitting Database
The Shear-Wave Splitting Database is a mirror of the Géosciences Montpellier's SplitLab Shear-wave splitting database that provides access to this valuable database using the SPUD system and its customized Google Maps interface.
EARS - EarthScope Automated Receiver Survey
EMERALD - a software framework for seismic event processing
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.

PDF/PSD Bulk Data Delivery System
PDF/PSD Bulk Data Delivery System is an automated system that accepts BREQ_FAST-formatted requests and provides users with the requested PSD data files (daily bin files).
Western US Ambient Noise Cross-Correlations
Vertical component ambient noise cross-correlation Empirical Green's Functions for the Western US using USArray data.
The DMC archives phase arrivals from the USArray Array Network Facility in addition to other DMS sources. The event bullentins are added to the DMC's event tables, making them available via the standard event query interfaces. The original submissions are also available as products.
Magnetotelluric Transfer Functions
USArray magnetotelluric transfer functions calculated from USArray MT stations by Oregon State University are availble from the SPUD system and also directly from the DMC's website in the EDI format.
Other data products available from the IRIS DMC
Film chip images from the World Wide Standardized Seismograph Network
Calibration data from IRIS/IDA portion of the GSN
Station Digests for USArray Transportable Array stations
