Towards probing Earth’s upper mantle with daily magnetic field variations: exploring a physics-based parametrization of the source

Abstract The electromagnetic (EM) field variations capable of probing the electrical conductivity of the upper mantle and mantle transition zone have a period range between a few hours and 1 day. At these periods, the dominant source of the EM signals is the ionospheric current system, which has a c...
