Based on data obtained by ionospheric midlatitude ionosondes and incoherent scatter radar (Irkutsk), we have studied the ionospheric response to the 15 December 2006 magnetic storm. During the main storm phase, ionospheric stations registered several positive disturbances during which critical frequencies (foF2) were higher by 1-4 MHz of a quiet level. The increase in the critical frequencies was accompanied by significant variations in a peak height of the F2 layer. The analysis of the temporal variations in foF2 and hmF2 led to the conclusion on the impact of large-scale wave processes on the ionization distribution at the F2 region heights. The increase in electron and ion temperatures of 200 - 300 ºK to relatively quiet conditions was registered by the HP radar at Irkutsk. Modeling the distribution of ionospheric characteristics showed that the best agreement between the experimental and calculated parameters of the ionosphere can be reached by adjusting the model of the neutral atmosphere and the rate of vertical drift
Keywords: magnetic storm, ionospheric disturbance, critical frequency, electron temperature, ionospheric plasma simulation
