IRIS, a consortium of over 91 institutions, operates a global network of 128 permanent seismic stations and a pool of over 400 portable instruments. The data likely contains recordings of earthquakes and active source experiments from stations distributed worldwide. The consortium was formed in 1984 and supports research for earth scientists in the U.S. and internationally.
Use Cases
- Detect and locate earthquakes based on seismic waveforms recorded by the Global Seismographic Network.
- Analyze Earth's crustal structure based on active source reflection and refraction data from PASSCAL portable instruments.
- Model seismic wave propagation and attenuation based on time-series data from globally distributed stations.
- Study temporal patterns in seismic activity based on continuous recordings from permanent stations.
Strengths
- Data originates from a major consortium of over 91 research institutions, suggesting institutional rigor.
- The Global Seismographic Network aims for 128 permanent stations, indicating a planned global coverage.
- The PASSCAL program operates a pool of over 400 portable instruments, providing flexibility for targeted experiments.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to nasa_earthdata, as station deployment details are not specified.
Provenance
- Source
- Incorporated Research Institutions for Seismology (IRIS) Consortium
- Collection Method
- Acquired via the IRIS Data Management System from the Global Seismographic Network and PASSCAL portable instruments.
- Geography
- Global, based on the goal of uniformly deploying stations over the Earth's surface.
