Seismic Normal Mode Centre Frequencies and Uncertainties for Core-Mantle Boundary Study

A table of centre frequencies and uncertainties used in the 2023 study "Evidence for a kilometre-scale seismically slow layer atop the core-mantle boundary from normal modes". The data is from the supplementary materials of the Geophysical Research Letters paper authored by researchers from the University of Cambridge.

Use Cases

• Calibrating Earth structure models based on the provided centre frequencies.
• Assessing model uncertainty in seismic tomography using the provided frequency uncertainties.
• Validating observations of a seismically slow layer at the core-mantle boundary.

Strengths

• Data is directly associated with a peer-reviewed publication in Geophysical Research Letters.
• The table is identical to the supplementary materials of the cited 2023 paper, ensuring provenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.

Provenance

Source

Supplementary materials of Russell et al. (2023), Geophysical Research Letters.

Collection Method

Likely derived from seismic normal mode observations and analysis.
