This page describes the IRIS (SAGE) component of EarthScope Data Services. This is just one part of the broader EarthScope organization, and the information shown here should be treated as historical context.
EarthScope Data Services (DS) has very specific charges and consists of several components or “nodes”. These nodes work together to ensure the smooth flow of GSN and PASSCAL data from the stations to the seismological research community.
Data Services Nodes
- Data Management Center
- IRIS/USGS Data Collection Center
- IRIS/IDA Data Collection Center
- PASSCAL Instrument Center
- University of Washington
- Array Network Facility
- Kazakhstan Seismic Data Center
EarthScope DS is composed of seven distinct nodes. The Albuquerque Seismic Laboratory (ASL) and the UCSD/IDA DCCs collect data from the GSN, perform QA on the data, convert the data to SEED and send the GSN data to the DMC. The EarthScope Primary Instrument Center (EPIC) performs QA and reformatting for PASSCAL data. The Array Network Facility (ANF) is charged with ensuring that USArray/Transportable Array data flow to the DMC and that proper metadata is available. The Kazakh National Data Center in Almaty performs QA on data from the numerous arrays and stations in Kazakhstan before forwarding the data to EarthScope. The UW, as the host of the EarthScope data archive, produces data products as well as provides feedback on MUSTANG Quality Assurance System with an emphasis on how MUSTANG can be used with data from regional networks. The DMC in Seattle is the home of the EarthScope data archive and serves as the primary distribution point for EarthScope data.
The DMC on behalf of EarthScope DS organizes seismic data workshops around the world, including how to handle network data and metadata and diverse topics in the Advanced Studies Institutes.
