The features of electron density behavior in the ionosphere-plasmasphere system above equatorial station Jicamarca in the end of September 2011



We present the analysis of the ionosonde and incoherent scatter radar (ISR) data of ionospheric parameters over Jicamarca (Peru) in quiet conditions and during geomagnetic storms on 22—29 September 2011. According to ISR data the estimation of the ionospheric contribution to the Total Electron Content (TEC) was carried out. These observation data are compared with GSM TIP model calculation results. The features of the electron density Ne behavior in the equatorial ionosphere and, in particular, F3 layer behavior, were identified. The agreement of the model calculation results and observation data analysis was obtained in quiet conditions and during geomagnetic storms.
