Pre-CSRM: An uppermost mantle seismic Pn-velocity in continental China

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 <strong>95,878 </strong>Pn travel times manually picked from the recordings of <strong>3,446 </strong>seismic stations deployed in and around continental China for a total of <strong>6,787 </strong>seismic events between 1992 and 2020.
