Fig. 6From: A simple method to evaluate the uncertainty of magnetotelluric forward modeling for practical three-dimensional conductivity structure modelsTrajectories (lines) of synthesized a \(Z_{{x_{j} y_{j} }}\) and b \(Z_{{x_{j} x_{j} }}\) (circles) with respect to the azimuth for selected three periods at site NM04 of the NW Pacific models. The values are normalized by \(\left| {\mu_{{{\text{sk}}}} } \right|\) or \(\left| {\mu_{{{\text{tr}}}} } \right|\). Gray shades indicate the range of \(1 \pm {\text{CV}}_{{{\text{sk}}}}\) or \(1 \pm {\text{CV}}_{{{\text{tr}}}}\). Colors correspond to those in Fig. 4Back to article page
