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

<p>The raw geomagnetic data are provided by the Geomagnetic Network Center of China,Institute of Geophysics, China Earthquake Administration. &nbsp;The raw data for this research&nbsp;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&nbsp;<br> transfer function complex A and B of the study.</p> <p>The format of the data is &rsquo;.mat&rsquo;, please open it by MATLAB software. &nbsp;The initial cell array&nbsp;of data is one column, including successively six frequency bands:</p> <p>0.001&ndash;0.005 Hz,<br> 0.005&ndash;0.01 Hz,<br> 0.01&ndash;0.05 Hz,<br> 0.05&ndash;0.1 Hz,<br> 0.1&ndash;0.2 Hz,<br> 0.2&ndash;0.5 Hz</p> <p>Every frequency band contains four columns. &nbsp;The first and second columns are longitude&nbsp; and latitude of the stations, and the third and fourth columns are the coefficients of the&nbsp; magnetic transfer function complex A and B, respectively. &nbsp;There are 98 rows, which indicates 98 stations in Mainland China.&nbsp; The&nbsp;QZ station which is utilized to demonstrate the processes is on eighteenth row.</p>
