Abstract

A statistical study of quiet time foF2 diurnal variation of two West Africa stations (Dakar and Ouagadougou) is examined through seasons and during solar minimum and maximum phases. It is shown that during solar minimum and for all seasons both stations foF2 exhibit the same variability with more and less deep trough between 1200 LT and 1400 LT. foF2 profiles are afternoon predominance profiles except during winter and for Dakar station where the profile is morning predominance peak. During solar maximum, foF2 profiles show different behavior only for spring and summer where Dakar foF2 profiles are plateau profile and dome profile, respectively. For these seasons Ouagadougou profiles are morning predominance profile and noon bite out profile, respectively. At daytime there is more ionosphere at Dakar station than Ouagadougou at all seasons and for the solar cycle phases involved.
