The data contains the geomagnetic data from 37 observatories in East Asia. The <em>Mag_lat_lon</em> matrix is the observatory location. The first column represents latitude, and the second column represents longitude. The 12 rows in <em>MAG </em>cells represent the months from January to December, the 37 columns in <em>MAG </em>cells represent the observatories corresponds to <em>Mag_lat_lon. </em>Each cell is a 96×3 matrix, the first, second, and third columns represent the X, Y, and Z components of the geomagnetic field. The sampling interval is 15 minutes from 00:00 to 23:45 UT.
