Short summary

The electrical conductivity of the Earth's ionosphere is an important parameter in the study of the polar, auroral currents that produce magnetic disturbances on the ground. Yet the values of the conductances, and how they vary, are not known with great precision. In our study we tested a method for deriving the conductivity values that requires use of three empirical models for the electric fields above the ionosphere and the magnetic field perturbations both on the ground and in space.
