Fig. 15From: 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 TNV48 from USArray. The black color indicates the results calculated by non-storm data observed from 00:00 on June 19 to 00:00 on June 21; the red color indicates the results calculated by storm data observed from 00:00 on June 22 to 00:00 on June 24Back to article page
