... anisotropic model using various components of the impedance tensor and examine the capability of the inversion to recover the true model. Using the full impedance tensor recovers a result closest to the true model, whereas using only off-diagonal or on-diagonal components results in models more inconsistent...

..., it is still not completely reliable when applied in strong urbanization contexts as the presence of cultural noise on magnetotelluric signals may significantly affect the MT impedance tensor estimates. Currently, the detection and mitigation of cultural noise on MT data is one of the main challenges to make...
