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 characterizations

  1) stack MCCC aligned P waves to obtain regional specific P wavelets 2) Backprojection rupture imaging & accompanying peak beam power as f(time) 3) Chuck Ammon's R1 STFs 4) Deconvolve body wave synthetics, then stack 5) moment-rate spectra from STFs.
  Status: Charter approved, in progress.

• USArray Super Stacks

  USArray 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. To be continuously updated.
  Status: Charter approved, in progress.

• ShakeMovie Project (Princeton) synthetics

  Convert the ShakeMovie 1D and 3D synthetics to SEED and add to the DMC's archive.
  Status: 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.

• Infrasound based product

  The signficant volume of infrasound and atmospheric pressure measurements being collected by the Transportable Array is an opportunity to perform bulk processing and provided a derivative product to that community. Product proposals are being solicited from the infrasound community.

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.

• PDF/PSD noise measurement

  Provide data characterization measurements derived from the PSDs calculated for the PDFs produced in the DMC's QUACK system. What characteristic would be most useful?

• Microseism index computation from PSD/PDF data

  ala Aster, McNamara and Bromisirski. This base index can be correlated with climate indexes, other uses as well?

• Continuous beam forming and F-K analysis

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