Datasets for "Continental fragments in the South China Block – constraints from crustal radial anisotropy"

This project contains the datasets needed to produce the radially anisotropic crustal shear-wave velocity model in a manuscript submited for publicaiton with Journal of Geophysicsl Research - Solid Earth.

The tar.gz file has the following files:

T-T.CCFs:                          Love wave cross-correlation functions (CCFs)

Z-Z.CCFs:                         Rayleigh wave CCFs

readme                              readme

stns.txt                               station coordinates

Each of the T-T.CCFs and Z-Z.CCFs folders contains the final stacked CCFs in SAC format between all available station pairs, e.g., 

COR_S003_S005.SAC

COR_S003_S007.SAC

...

...

The CCF file name show the names of station pairs (e.g., S003, S005, S007).

With these cross-functions, following a standard ambient noise inversion procedure, i.e., measuring surface wave dispersion for both Rayleigh and Love waves, developing dispersion models for both waves, and appying a joint inverting, the radial anisotropic crustal shear wave model presented in our study can be reproduced. For details of the method, readers are referred to the following papers:

The two datasets are the only data needed to produce the model in our study.
