基于线性台阵背景噪声伴随层析成像方法

This is providing the final models, REGFs and codes in the paper: Zhang C., Yao H., Liu Q., Zhang P., Yuan Y., Feng J., Fang L., 2018. Linear array ambient noise adjoint tomography reveals intense crust-mantle interactions in North China Craton. J. Geophys. Res. , 123, DOI: 10.1002/2017JB015019

                             图-1 基于线性台阵背景噪声波形伴随成像法流程示意图

1 Finalmodel: the inverted Vs model: M14_Fang_final(Figure 8d), M23_Duan_final(Figure 10b)

2 REGFs：reconstructed empirical green function (observed data)

3 seiscode: source code including two parts:

3.1) 3D/2D :the 3D/2D data transformation method

3.2) seisNoise2D :the 2D linear array ambient noise tomography

This is the source code without users' manual about how to use it. If you need a detail description, feel free to send an email to Chao Zhang ([email protected]) with a brief introduction about yourself and why you want to use it. We will be happy to help.

基于背景噪声和远震体波联合伴随层析成像方法(实时更新)

Following the workflow of part-1, we develope the joint inversion of ambient noise and teleseismic body-wave for linear arrays based on adjoint tomography.
