Auroral ionospheric conductivities: a comparison between experiment and modeling, and theoretical f 10.7 -dependent model for EISCAT and ESR
International audience Several authors have published models of auroral conductances in the past. Some of them are based on theoretical approaches; others are the result of observations. The data bases for the latter models range from 8 h to 3 years of experiments. In this paper, we show the results...
