The tomographic inversion that produced this model has been documented in this paper. The software for carrying out this inversion F3DWI is documented in my second book: Full-3D Seismic Waveform Inversion – Theory, Software and Practice.

A text (ASCII) file of the model can be downloaded using the following link. The file is about 12 Gb. So it is preferable to right-click the link and choose from the drop-down menu “save link as”. The file has 5 columns:
column 1 : latitude (degree)
column 2: longitude (degree)
column 3: depth (km)
column 4: Shear-wave speed Vs (km/s)
column 5: P-wave speed Vp (km/s)
file link: CVM-S4.26
the density model (Note: the grid is different from that in the Vp, Vs file and the columns are: longitude, latitude, depth (km, negative), density (kg/m^3))
