The uppermost mantle seismic Pn-velocity model is inverted from a new tomographic scheme integrating a combined dataset of 32,427 absolute Pn travel times and 62,431 interstation Pn differential travel times (Ma et al., 2023). The model has spatial resolutions of 0.75° × 0.75°–1° × 1° in the north-south seismic belt and 1.5° × 1.5°–3° × 3° in other regions. The combined Pn travel time dataset used for the inversion of the model is selected from 95,878 Pn travel times manually picked from the recordings of 3,446 seismic stations deployed in and around continental China for a total of 6,787 seismic events between 1992 and 2020.
