High Level Data Products at the IRIS DMC Tim Ahern, IRIS Director of Data Services Rick Benson, IRIS Director of Operations
What is a data product? In the broadest sense products are data, from raw data to derivative results to high level knowledge summaries spanning entire scientific information domain. EarthScope/USArray data product levels: 0: Raw continuous and event-segmented data 1: Quality controlled data 2: Products derived from data using accepted methods 3: Products needing technical analysis & interpretation 4: Products integrating geological/geophysical data 2
LEVEL 4 Integrated Research Products LEVEL 3 Seismological Research Products LEVEL 2 Derived Information Standard Processing Product Levels – Adapted from National Research Council Committee on Data Management and Computation (CODMAC) 3 LEVEL 1 Quality Controlled Data LEVEL 0 Raw Data
The IRIS DMS data product effort Mission: produce level 2 data products and manage products at all levels to provide: Stepping stones (pre-processing) for further research Insight into the data for selection and E&O Direct interpretation for confirmation, etc. Bridges to other disciplines, exporting seismological observations Community guidance via a Data Products Working Group 4
