Fig. 16From: Influence of geomagnetic storms on the quality of magnetotelluric impedanceComparison of the MT sounding curves calculated by single-site and remote reference data processing using the storm and non-storm data observed at site TNV48. a–d Show the apparent resistivity. e–h Show the impedance phase. The horizontal axis denotes the period in seconds. The MT sounding curves longer than 40 s are similar and cover the XY and YX componentsBack to article page
