China Geophysical Reference Model-Level II data

Level II data is the seismic data and intermediate processing results (such as dispersion curves, receiver functions, Pn travel times, etc.) screened for the construction of the reference model by the "China Geophysical Reference Model Construction Group".

You can browse the details and download the Level II data.

• Phase velocity model, earthquake centroid parameters, processed earthquake surface wave waveform, empirical Green's functions, measured phase velocity dispersion curves, and the measurement software of the event-station phase velocity dispersion curve in the North-South Seismic Belt (NSSB). [Link 1] [Link 2]
• Manually-picked Pn travel times, uppermost mantle seismic Pn-velocity model, and epicenter locations in continental China. [Link 1] [Link 2]
• Event Pn waveform data in continental China. [Link 1] [Link 2]
