Simulation of Seasonal Variations of Electron Concentration in the Ionospheric F2-Peak for Midnight and Noon Local Time
ABSTRACT
The experimental database obtained at Kharkiv incoherent scattering radar for the period from 1986 till 2002 had been used for modeling seasonal variations of the electron concentration Nm in the ionospheric F2-peak. The regression dependencies of the Nm upon the solar activity index were built. Model coefficients of regression are obtained for every month. Seasonal variations of Nm for midnight and noon local time and for different levels of solar activity were recovered. A comparison between calculated and experimental values was carried out. Good matching between them at any solar activity level was achieved. The particularities of seasonal variations for various phases of solar activity are considered. The obtained results are used for upgrading the empirical ionospheric model of the Central European region.
