Investigation of electron density variation in some regions of the Ionosphere at Nsukka, Nigeria
The variations of electron density in some regions of the ionosphere at Nsukka (6.50° N and 7.2° E) in Nigeria were investigated. The dependence of these variations on the 11 year solar cycle, seasonal changes, diurnal and altitude effects were analysed. The results of the analyses reveal that the electron density concentration in the ionosphere is dependent on heights. Our results also...
