Fig. 12From: 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 130. a–d Show the apparent resistivity. e–h Show the impedance phase. The horizontal axis denotes the period in seconds. The storm result and storm-RR result coincide and cover each otherBack to article page
