Comparative study of fof2 diurnal variation between the dakar and ouagadougou stations during the one-day, two-day and three-day shock periods for the solar minimum and maximum of cycle 21-22
This paper deals with the comparative study of foF2 diurnal variation between the Dakar and Ouagadougou stations during shock activity of variable duration (one-day, two-day and three-day shock) for the solar minimum and maximum phases of cycle 21-22. At solar minimum, the curves of the diurnal variation of foF2 of two stations exhibit the signature of vertical drift indicating the presence of a strong electrojet. Except for the one-day shock, the ionization is strong at the Dakar station compared to the Ouagadougou station during this phase throughout the day.
