CRESCENT Gen0: 3D Community Velocity Model for Earth's Crust and Mantle

A 3D velocity model built by a joint Bayesian inversion of over 20 years of radial receiver functions and ambient noise Rayleigh waves. The model includes velocity uncertainties in the crust and upper mantle and is intended as a foundation for future higher-resolution models. It was authored by Bin He and last updated in May 2026.

Use Cases

• Benchmarking new tomographic models based on consistency with previous models mentioned in the description
• Incorporating velocity uncertainties into seismic hazard assessments based on the described uncertainty feature
• Providing a foundational model for full waveform inversion approaches as stated in the description

Strengths

• Model incorporates over 20 years of seismic data as stated in the description
• Includes velocity uncertainties for the crust and upper mantle as a described feature
• Released under a CC-BY-4.0 license, facilitating open use

Limitations

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