Description This dataset comprises vertical component of continuous seismic waveforms used to calculate the noise cross-correlation function of Rayleigh wave, originating from 52 seismic stations meticulously documented by the Institute of Earthquake Forecasting, China Earthquake Administration (CEA). Each seismic waveform are band-pass filtering. The sampling rate is set at 0.2, equivalent to 5 Hz. Rayleigh wave phase velocity dispersion curves were measured at periods of 2~40 s with an interval of 1 s from cross-correlations of vertical components of seismic noise data. A total of 8285 noise cross-correlations are finally archived. These cross-correlations have separations longer than two wavelengths and signal-to-noise ratios of surface waves larger than five. A total of 5228 high quality Rayleigh wave phase velocity dispersion curves are finally archived.
The vertical component waveforms files are stored in the directories as: ~/Seismic_waveform/Array.tar.gz (e.g., ~/Seismic_waveform/SJ-Array.tar.gz). The noise cross-correlations function files are stored in the directories as: ~/ NCF/station1-station2.dat (e.g., NCF/SJ01-SJ01.dat). The dispersion data are stored in the directories as: ~/ Disper/CDisp.station1-station2.dat (e.g., Disper/CDisp.SJ01-SJ01.dat). The 3-D S-wave velocity and azimuthal anisotropy data are stored in the directories as: ~/Velocity/SJ_3D_Vs.txt.

Type Vertical component of seismic waveform data and header information (sampling rate). All the noise cross-correlations functions were sorted in data format. The first two lines are longitudes, latitudes and elevation of source and receive stations, respectively. The following lines are Period, GAB and GBA. GAB is the EGF (empirical Green’s function) from source A to station B, while GBA is from source B to station A. All the Rayleigh wave phase velocity dispersion curves were sorted in data format. The first two lines are longitudes and latitudes of source and receive stations, respectively. The following lines are Period, Phase-velocity. The 3-D S-wave velocity and azimuthal anisotropy data are stored txt format.
Format .dat and .txt format, available in notebook. SAC format can be read directly using SAC, ObsPy, MATLAB, et al.
