J. Lilensten et al., AURORAL IONOSPHERIC CONDUCTIVITIES - A COMPARISON BETWEEN EXPERIMENT AND MODELING, AND THEORETICAL F(10.7)-DEPENDENT MODEL FOR EISCAT AND ESR, Annales geophysicae, 14(12), 1996, pp. 1297-1304
Several authors have published models of auroral conductances in the p
ast. Some of them are based on theoretical approaches; others are the
result of observations. The data bases for the latter models range fro
m 8 h to 3 years of experiments. Tn this paper, we show the results of
our own modeling, based on a coupled kinetic/fluid approach. We compa
re these results to the statistical model based on 3 years of experime
nt. We then model the auroral ionospheric conductances above EISCAT an
d the EISCAT-Svalbard Radar for different solar-activity indices. Thes
e modeled conductances are fitted with a simple law depending on the f
(10.7), index and on the solar zenith angle.
