Theoretical Calculation of Daytime and Nighttime Profiles of Electron Density of F2-Region Plasma in Middle-Latitude Ionosphere for Quiet Geomagnetic Conditions

The results of theoretical simulation of the electron density altitude profile of the mid-latitude magnetically quiet F2 region at midday and midnight are presented. The solution of the linear differential equation of atomic oxygen ions continuity is searched in the form of product of two functions. The approximation of divergence of the ionospheric plasma flux in the form of a partial derivative with respect to altitude is substantiated. The contribution of the radial component of the electric drift to the total velocity of the plasma motion is estimated.
