a Regional mean 1D resistivity profile estimated from the average ssq impedance (SSQ1D, solid black line). The SSQ1D model is compared with the optimal mean 1D profile obtained by an areal average of the synthetic 3D model (red solid line), UHS10 (dashed-dotted line), UHS 100 (dotted line), and UHS1000 (dashed line). b Synthetic data and inversion responses corresponding to those for the SSQ1D model
