Abstract

In an earlier paper we obtained semi-empirical models describing the dependencies of the electron density (N) and of the parameter of development of the F1-layer (A) on thermospheric neutral gas characteristics, the zenith angle of the Sun, on the daily, and averaged index of soar activity F_10.7. These models are based on generalizing series of experimental data using the regression equations describing the above-mentioned relationships. This was possible in connection with the existence of a rigid connection of N and A with the state of the thermosphere. This paper presents the regression equations of the form described above but using relative values of solar ionizing radiation energies in the range 5.0-105.0 nm.
