Current Understanding of the Equatorial E x B Drift velocities in the African Sector: A Short Review
Publikováno v:
Journal of Nigerian Society of Physical Sciences, Vol 4, Iss 1 (2022)
A short review of the pattern and morphology of the equatorial plasma drift velocities, particularly during the evening-time Pre-reversal enhancement (PRE) period in the African region had been presented. The seasonal PRE peak values across some loca

Abstract Scale height is an important ionospheric parameter which determines the shape of the topside electron density profile. In this paper, the latitudinal variation of α‐Chapman scale height (Hm) is investigated using data obtained from four g

Trans-ionospheric signals such as the Global Positioning System (GPS) signals propagating through irregular ionospheric plasma structures may experience phase variation and amplitude fades causing degradation in system performance. This paper investi

The height of the peak electron density (hmF2) is crucial in the study of some ionospheric electrodynamics and for high frequency (HF) radio communication circuit planning. We validated the three hmF2 model options of the 2016 version of the Internat
