Seismic Waveform Tomography Data for the Central and Eastern Mediterranean Upper Mantle

Seismic waveform tomography data from a 2019 study by Blom, Gokhberg, and Fichtner, corresponding to the upper ~500 km of the Earth. The dataset includes raw and processed seismograms, station and earthquake information, window selections, and synthetic seismograms from iterative gradient-based inversion across several frequency bands. The inversion involved a hundred iterations, with synthetic data stored for key iterations where human interaction occurred.

Use Cases

• Validate full waveform inversion (FWI) algorithms based on the provided raw and synthetic seismograms.
• Study the elastic structure of the Central and Eastern Mediterranean upper mantle using the provided model files.
• Analyze the progression of seismic models and misfit across the ~10-20 iterations per frequency band.
• Reproduce the figures from the original 2019 study using the included data and scripts.

Strengths

• Includes data from a hundred iterations of a deterministic, gradient-based inversion process.
• Contains both raw/processed seismograms and synthetic seismograms for key iterations, enabling direct comparison.
• Model files are provided in multiple formats (ses3d ASCII and .vtu) for flexibility in visualization and analysis.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment for large-scale processing.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
