About SPUD

SPUD Version 3.0

The Searchable Product Depository (SPUD) is the IRIS DMC's primary data product management system. Complementing the DMC's SEED and assembled data archives, which contain time series recordings, the SPUD system primarily contains derivative data products of other types (images, movies, etc.) created either at the DMC or by members of the community.

For users SPUD is the query and access point for these products. The web interfaces allow users to search for products using customized queries across product and event details. Users can search across all product types at once or within specific product types. SPUD also has web service interfaces for programmatic discovery and access to the data products.

If any products from SPUD are used in your research please be sure to cite the identified author of the product and the IRIS DMS [Citation Information].

About Infrasound Event Products

The TA Infrasound Reference Event Database (TAIRED) is a user-supported evolving database that serves as a reference event depository where researchers can contribute new events, provide a new solution for an existing event and find samples of infrasound events for their use.

In addition to the events contributed by users and those compiled by IRIS DMC TAIRED team, as indicated by the Author column, this database also includes automated events built using the AELUMA (Automated Event Location Using a Mesh of Arrays) algorithm developed by Groot-Hedlin and Hedlin (2015).

Two criteria are used to classify events in this database, source type and status:

Events sources includes the following types:

Status indicates the type of analysis that has gone into building the events:

A list of the contributing infrasound stations to the record sections for each event and the processing parameters used by AELUMA are available from the corresponding event page.
