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 F10.7. 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.
