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 Earth Model Products

The Earth models presented here are contributed to the IRIS Earth Model Collaboration (EMC) by various researchers.

Two general types of model are available for download:

  • Tomography Models:
    The contributed Earth models in their original format and in a common netCDF (network Common Data Form). A model overview page provides a summary of the model.

  • Reference Models:
    Most EMC Earth models are expressed as perturbations relative to a particular reference 1-D model. These reference models are available for download in expanded comma separated value (CSV) file format with the first two lines representing the file’s header.

For model visualization and additional information about the models visit the IRIS EMC Product Page.

Depth Coverage: -5.0 - 50.0 km
Areal Coverage: Latitude: -12.0 to -41.0 Longitude: -75.0 to -64.0
Model Description The model incorporates broadband seismic data from 20 seismic networks deployed incrementally in the Central Andes from 1994 May to 2012 August, to image the shear wave velocity structure of the South American Cordillera.
Data Set Description [Ward et al., (2013)] The dataset includes the absolute S-wave velocity structure across the Central Andes from ambient noise tomography.
