| Abstract: | This paper introduces an iteration method for the downward continuation of potential‐field data from a horizontal plane, and compares it with the conventional frequency‐domain method (Fourier transform) using 2D and 3D model tests. The paper evaluates the two methods in terms of the results, i.e. downward‐continuation distance and stability. The iteration method proves to be more stable and able to downward continue the potential for a greater distance than the Fourier transform method. |
