Seismic data processing package developed：

    1.  Cartesian Meshing Spherical Earth (CMSE): A code package to incorporate the spherical earth in SPECFEM3D Cartesian simulations. This is an update package of SPECFEM3D_cartesian code. Compared with the SPECFEM3d_cartesian, our code package is more accurate in simulating regional wave propagations and can be used in polar regions. Compared with SPECFEM3D_globe version, our code is more efficient in computation and storage. Available by clicking https://github.com/LiGuoliangMSU/CMSE.

    2.  Time-frequency phase weighted stacking method: This non-linear stacking method can be used to stack the daily ambient noise cross-correlations without distorting the dispersion characters. Besides, this code is more efficient than Schimmel’s. Available by email: liguolia@msu.edu/guoliang1104@qq.com

    3.Joint inversion package: This package can extract surface wave dispersion curves, Rayleigh wave ellipticity and teleseismic body waveforms and then jointly invert them for the basin-wide shallow velocity structures. Available by email: liguolia@msu.edu/guoliang1104@qq.com

    4.     The Deconvolved Autocorrelation (DA) package: The proposed DA method resolves issues related to spectral variations of waveforms and signatures of the used bandpass filter, which can help to obtain genuine subsurface velocity changes.
