| Zusammenfassung |
| The Coronal Mass Ejections (CMEs) and Co-rotating Interaction Regions (CIR) driven
geomagnetic storms may affect the ionosphere sometimes severely and could result in what is
called ionospheric storm effects. This presentation will focus on the statistical analyses of the
ionospheric storm effects over middle, equatorial and low latitude stations located within
20∘E and 40∘E in the African sector during the time interval 2000 - 2016. Comprehensive
analyses of Global Positioning System Total Electron Content (GPS-TEC) data were
performed based on storm criteria of Kp ≥ 3 to identify disturbed days. The effects on the
ionosphere due to CME and CIR driven geomagnetic storms were studied. The dependence
of ionospheric storms on solar activities, season and diurnal variation will be discussed. |
