The Vertical Distribution of Electrical Conductivity in the Upper Atmosphere

Abstract

Using available materials of recent rocket measurements, a calculation is made to obtain the atmospheric and ionospheric models of the upper atmosphere between 60km and 400km. On the basis of these models the vertical distribution of electrical conductivity and its height-integrated values for three ionospheric regions F, E and D are obtained. The results show that the conductivity of the E-region, especially near 100km, is most predominant, so that this region is most probably effective to the electrical currents producing daily magnetic variations.
