Paraná Basin 3-D conductivity model

<p>This data product includes Magnetotelluric (MT) and Geomagnetic Deep Sounding (GDS) datasets from the Parna&iacute;ba Basin, which are used for data analysis in ModEM. The 3-D resistivity model (Parana3D_res__NLCG_077.rho) and impedance tensors (Parana3D_fwZ_NLCG_077.dat) were derived by performing forward calculation using the included datasets. This data was analyzed and presented in the paper "Estimating Geomagnetically Induced Currents in Southern Brazil Using a 3-D Earth Resistivity Model."
