Summary alt text

In this database, I collected several whole mantle tomography models. I converted them into nc files for conformity and easy-access. Each nc files contain 4 variables: depth, longitude, latitude and "v". The "v"alues could represent:

  • S wave or P wave speed (in km/s)
  • S wave or P velocity purturbation (%)
  • density (in kg/m^3)
  • attenuation factor Q
  • anisotropic parameters
  • etc.

Please refer to the file name and the comments within each nc files for the meaning of "v"alue.

The c++ tools to read the nc files and to get value at certain location are provided in src

Dependencies are

  • netcdf-4.6.1
  • (optional, for plotting) GMT-5.4.4

Here are details about data sources and preprocessings to make these nc files:

    Changes : lose variables "dlnvp", "dlnvs", "vp", "vs", "phi", rename variable "xi" to "v". In paper it reads xi = (vsh^2/vsv^2). In this nc file, the comment reads xi=(vsv^2/vsh^2), which could be a typo.

    Changes : created GAP_P4.01 ~ GAP_P4.29, then doubled the depth layer. For example: 29 and 50.999 km get values from GAP_P4.01
