SWChinaCVM-1.0

This is a reference 3-D P- and S-wave community velocity model of the crust and uppermost mantle in southwest China (SWChinaCVM-1.0, DOI:10.12093/02md.02.2019.01.v1), obtained by joint body and surface wave traveltime tomography. This work is supported by the China Seismic Experimental Site（CSES）.

• Model Data Format: Lon Lat Dep(km) Vp(km/s) Vs(km/s)

• Method: Joint inversion of body wave (P and S-wave) travel time and Rayleigh wave traveltime data (Fang et al., (2016), JGR).

• Grid space: Horizontally 0.5 degree interval, vetically at depth 0, 5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70 km.

• Depth is relative to the surface (0 km).

The resolutions of Vp and Vs model are calculated according to the checkerboard resolution test. Grid Nodes with resolution higher than 0.7 are considered as well resolved.

• Format: Lon Lat Dep(km) resolution_of_Vp resolution_of_Vs
