DSurfTomo

DSurfTomo is a surface wave inversion program which can directly invert surface wave dispersion data to 3D shear wave speed without the intermediate step of constructing the phase or group velocity maps. A fast march method (FMM) is used to compute, at each period, surface wave travel times and ray paths between sources and receivers. This avoids the assumption of great-circle propagation that is used in most surface wave tomographic studies, but which is not appropriate in complex media.

For detail description of the method, please refer to: Fang, H., Yao, H., Zhang, H., Huang, Y. C., & van der Hilst, R. D. (2015). Direct inversion of surface wave dispersion for three-dimensional shallow crustal structure based on ray tracing: methodology and application. Geophysical Journal International, 201(3), 1251-1263.

This is the source code without users' manual and examples about how to use it. If you need a detail description and some examples, feel free to send an email to Hongjian Fang (fanghj@mail.ustc.edu.cn) with a brief introduction about yourself and why you want to use it.

We will be happy to help.
