Data Products
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.

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
Event Plots
 |
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.

Back-projection
 |
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.

EARS - EarthScope Automated Receiver Survey
 |
The EarthScope Automated Receiver Survey (EARS)
calculates bulk crustal properties of IRIS stations using receiver functions. Originally developed at the
University of South Carolina, EARS continuously monitors for new events and stations updating the database when
new candidate data are found.

Event Bulletins
 |
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.
