Abstract

In the study the critical frequency of the F2-layer of the ionosphere data obtained at Ionospheric Observatory of Tomsk State University are analyzed. The analysis focuses on the study of the spectral composition and determining the long-term trends values of foF2. For the spectral estimation the anharmonic decomposition method is used. The result of research is establishing the dependence of a long-period trends character, periods values and the amplitudes of variations of foF2 values caused by the eleven-year cycle of the Sun activity and orbital movement of the Earth on time of a day and a season of year.
