Scientific paper

A method was developed to directly deduce the Hall conductance distribution Sigma(H) from ground magnetic and ionospheric electric field observations based upon an assumption for the ratio of the Hall to the Pedersen conductivity. The solutions are shown not to be unique because for a specific solution the value of Sigma(H) on certain parts of the boundary of the 2D domain has to be specified. In the presence of strong and isolated field-aligned currents, these boundary values become less influential, and the solution is shown to be virtually unique over a large area of the domain. In some cases, a rather restrictive relation between the electric field and the equivalent height-integrated current density is shown to hold what could be used to cross-check observation quality. The present formalism is applied to the observation of a Harang discontinuity obtained in northern Scandinavia simultaneously by the STARE coherent radar system and the IMS Scandinavian Magnetometer Array.
