A Continental-scale Seismic Observatory


Data from all USArray components are available through the IRIS Data Management Center (DMC) including:

  • Transportable Array
  • Flexible Array
  • Reference Network
  • Magnetotellurics stations

All USArray seismic data receive quality control at the IRIS Data Management Center (DMC), the Array Network Facility (ANF), the Array Operations Facility (AOF), or a Data Collection Center of the USGS in Albuquerque, NM or Golden, CO. Additionally, the IRIS DMC runs a suite of algorithms against all data arriving at the DMC in real time. In some cases, these algorithms are good indicators of data quality. All USArray MT data receive quality control through Oregon State University's (OSU) USArray Data QC group, where robust remote reference methods are used to generate MT transfer functions and induction vectors.

The IRIS DMC is the access point for you to gain access to waveforms, metadata, MT time series and derived data products from USArray stations.
