Abstract. Several authors have published models of aur-oral conductances in the past. Some of them are based on theoretical approaches; others are the result of observa-tions. The data bases for the latter models range from 8 h to 3 years of experiments. In this paper, we show the results of our own modeling, based on a coupled ki-netic/fluid approach. We compare these results to the sta-tistical model based on 3 years of experiment. We then model the auroral ionospheric conductances above EIS-CAT and the EISCAT-Svalbard Radar for different solar-activity indices. These modeled conductances are fitted with a simple law depending on the f 10.7 index and on the solar zenith angle. 1
