A method for numerical modeling of processes in near-Earth space plasma under natural and anthropogenic effects is presented. The method is implemented in a non-stationary model of the ionosphere-plasmosphere system, which allows one to calculate the distribution of characteristics of low-energy plasma along geomagnetic field lines of arbitrary size, taking into account ambipolar diffusion, photochemical processes, and interaction with a horizontal atmospheric wind. The mathematical model was used to study the physicochemical processes in the ionospheric plasma, the processes of the dynamic and chemical effects on this plasma medium. The results of modeling variations in the parameters of ions and electrons in the mid-latitude ionosphere and magnetosphere are presented.

Keywords:Ionosphere, plasmasphere, mathematical modeling, numerical simulating, technogenic impact, dipole geomagnetic field.
