Product Development List

The DMS data products development list includes the data products currently approved and in progress and those that are in consideration. Products may be entirely developed at the IRIS DMC or may be developed by the research community and transferred to the DMC. The IRIS Data Products Working Group is responsible for approving and reviewing specific products to be developed,

Have a data product idea? Feel free to suggest a data product.


Approved and in progress


  • Source Time Functions

    1) Chuck Ammon's R1 STFs and 2) simplified and robust STFs.
    Status: Charter approved, in progress.

  • Global Super Stacks

    Global data for all shallow earthquakes systematically stacked with enhanced stacking techniques to show both polarization and slowness, presentation based on the 1996 Astiz & Shearer poster.
    Status: Charter approved, in progress.

  • GPS displacement grams

    Conversion and archiving of the GPS displacement time series produced as a near real-time product by PBO/UNAVCO.
    Status: In progress, waiting on PBO and community input

In exploration


  • Synthetic seismogram service

    Create a web service that returns synthetic seismograms for selected parameters: model, location, moment tensor and source time function. Potentially limited to spherically symmetric models by on-demand processing requirements.

  • Noise toolbox

    This database of noise spectra will support two products: 1) microseism index and 2) noise polarization analysis

In consideration


  • Event Product Browser/Aggregator

    - Dynamically create event-specific web pages with relevant product
    created either by the DMC or externally (USGS, GCMT, etc.) - Research oriented and complementary to USGS pages

  • Aftershock sequence map

    -Self updating aftershock sequence and statistics map/animation following all major earthquakes as well as historical events.
    -Possibly extended to allow user custom time and space box for seismicity+statistics.
    Example: http://www.iris.edu/dms/staff/alex/Chile.aftershocks.mov

  • Amplitude mismatch test for user QC

    Plot/record peak amplitudes at all stations in different frequency bands following all M>6.0? events as a first step to track instrument gain problems in near-real time. http://www.iris.edu/dms/staff/alex/Peak_amp1.png http://www.iris.edu/dms/staff/alex/Peak_amp2.png

  • Relative station timing test for user QC

    Compare first arrival relative times between similar events to track station timing errors.

  • Continuous beam forming and F-K analysis

    - Targeting fixed regions
    - Targeting recent large earthquakes to record aftershocks
    - Potential collaboration with Keith Koper
