Fig. 8From: A simple method to evaluate the uncertainty of magnetotelluric forward modeling for practical three-dimensional conductivity structure modelsScatter plots of \({\text{CV}}_{{{\text{sk}}}}\) and \({\text{CV}}_{{{\text{tr}}}}\) with respect to the period and the magnitude of \(\mu_{{{\text{sk}}}}\) and \(\mu_{{{\text{tr}}}}\) scaled by square root of the period for the S Atlantic models. Symbols filled with black indicate the site that the sounding curves and the trajectories of the MT response to the azimuth are demonstrated in Figs. 7 and 9, respectivelyBack to article page
