An ionospheric and plasmaspheric model based on a numerical solution of continuity, momentum, and energy equations for O(+) and H(+) ions and electrons is developed. Diffusion approximations are compared with the full hydrodynamic description. The F2 region electron concentration calculated by diffusion approximation is found to be smaller than the concentrations corresponding to the hydrodynamic description. It is suggested that the significant discrepancy is due to hydrodynamic fluxes in the ionosphere. The two-ion diffusive distribution along the entire magnetic flux tube is different from the plasmaspheric ion distribution obtained by total hydrodynamic equations.
