| | Abstract | | 3D inversion approaches that can be applied to transient electromagnetic (TEM) and CSAMT data for a grounded-wire source are presented. For TEM method, the performances of inversions for the step and impulse responses are compared, and the resolution capability of ground-based and airborne methods are compared. For CSAMT method, inversion performances are compared when inverting electric and magnetic fields directly and when inverting the impedance data. |
