| Description | We construct a high-resolution Pn-velocity model in continental China through a new tomographic scheme simultaneously inverting event epicenter location and Pn-velocity and accurately accounting for the Pn propagation effects of irregular crustal thickness variation. The inversion integrates a combined dataset of 32427 absolute Pn travel times and 62431 interstation Pn differential travel times manually picked from the recordings of 2989 stations in and around continental China, yielding a model of spatial resolutions ranging from 0.75°×0.75° to 3°×3°. |
