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

<p>The&nbsp;uppermost mantle seismic Pn-velocity&nbsp;model is inverted from a new tomographic scheme integrating&nbsp;a&nbsp;combined dataset of 32,427 absolute Pn travel times and 62,431 interstation Pn differential travel times (<a href="https://doi.org/10.1029/2022JB025667">Ma et al., 2023</a>).&nbsp;The model has spatial resolutions of 0.75&deg;&nbsp;&times;&nbsp;0.75&deg;&ndash;1&deg;&nbsp;&times;&nbsp;1&deg; in the north-south seismic belt and 1.5&deg;&nbsp;&times;&nbsp;1.5&deg;&ndash;3&deg;&nbsp;&times;&nbsp;3&deg; in other regions.&nbsp;The combined Pn travel time dataset&nbsp;used for the inversion of the model is selected from <strong>95,878 </strong>Pn travel times manually picked from the recordings of&nbsp;<strong>3,446&nbsp; </strong>seismic stations deployed in and around continental China&nbsp;for a total of <strong>6,787 </strong>seismic events between 1992 and&nbsp;2020.
