Fig. 8From: Influence of geomagnetic storms on the quality of magnetotelluric impedanceMT sounding curves and coherence distributions during the storm and non-storm days using the data observed at site 142. The black color indicates the results calculated by the non-storm data observed from 00:00 on October 26 to 00:00 on October 29; the red color indicates the results calculated by storm data observed from 06:00 on October 29 to 06:00 on October 31Back to article page
