REGRESSION MODELS ANALYSIS OF THE DEPENDENCES ELECTRON CONCENTRATION OF THE F2 LAYER IONOSPHERE MAXIMUM ON SOLAR ACTIVITY AND YEARLY SEASONS BASED ON THE TOMSK IONOSPHERIC STATION DATA
Abstract and keywords
Abstract (English):
The paper considers the issues of constructing regression models the electron concentration of the ionospheric F 2 layer maximum dependence of solar activity. The series of continuous observations of the Tomsk ionospheric station from 1947 to 2024, covering 8 cycles of solar activity were studied. The electron concentration was taken at the time of the daily midday maximum. Regressions were built for each month of the year separately. The advantages and disadvantages of using daily and monthly median values of the ionospheric parameter are given.

Keywords:
