The data for the 'The Distribution of Underlying Electrical Materials in Mainland China Using Geomagnetic Data'

The raw geomagnetic data are provided by the Geomagnetic Network Center of China,Institute of Geophysics, China Earthquake Administration.  The raw data for this research are not publicly available due to government policies and laws. In order to allow researchers to reproduce the results in this work, we upload the processed coefficients of the magnetic 
transfer function complex A and B of the study.

The format of the data is ’.mat’, please open it by MATLAB software.  The initial cell array of data is one column, including successively six frequency bands:

0.001–0.005 Hz,
0.005–0.01 Hz,
0.01–0.05 Hz,
0.05–0.1 Hz,
0.1–0.2 Hz,
0.2–0.5 Hz

Every frequency band contains four columns.  The first and second columns are longitude  and latitude of the stations, and the third and fourth columns are the coefficients of the  magnetic transfer function complex A and B, respectively.  There are 98 rows, which indicates 98 stations in Mainland China.  The QZ station which is utilized to demonstrate the processes is on eighteenth row.
