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 Calibration Products

Network operators of seismic stations perform calibrations of the instrument at various times. These calibrations are used primarily to validate that the response metadata matches the actual response of the instrument. In some cases the calibration data is used to generate new response metadata.

These calibration products can include the calibration input signal, the recorded response to the input signal and/or a report summarizing the processed calibration data.

For the IRIS/IDA calibrations more information is available in the "Notes on processing random binary calibrations signals at IRIS/IDA GSN stations".
