In this paper the daytime vertical E → × B → drift velocity in the F-region of the equatorial ionosphere was estimated from the magnetic effect of the equatorial electrojet (EEJ) in West African sector for September equinoxes in 1993 during sola

A study on variability of the equatorial ionosphere was carried out at fixed heights below the F2 peak for two different levels of solar activity. The study covered height range of 100 km up to the peak of F2 layer using a real height step increase o

Ionosonde data recorded at Korhogo ( dip = - 0.67 ) were used to investigate the response of the equatorial ionosphere during the geomagnetic storm of April 7 and 8 of 1995 a year of low solar activity. The parameters used are the F 2 layer peak dens

We have used data from two equatorial stations in the African longitude sector to study the monthly variability of foF2. Diurnal, seasonal, and solar activity effects were investigated. The data established by this study are proposed as equatorial in

This study presents the results of the comparison of B0, B1 and hmF2 with ΔH. B0 and B1 are parameters used in the international reference ionosphere model for the calculation of the F region bottom side profiles. The parameter ΔH obtained from the

Ionosonde data recorded at Korhogo, Ce Longitude - 5.4, Dip -0.67) during a year of low solar activity (1995) were used to investigate ways of improving the representation of equatorial F2 peak height (hmF2) in the International Reference Ionosphere

The electron density profile in the F region bottomside is described in the International Reference Ionosphere (IRI) by two parameters: a thickness parameter B 0 and a shape parameter B 1. The models used for B 0 and B 1 in IRI are based on ionosonde
