Ionospheric Phase Scintillation during Solar Cycle 24 over West Africa: Analysis from GPS Stations at Koudougou and Ouagadougou (BF01)

SAWADOGO Wambi Emmanuel, Kaboré Salfo, Bassolé Mathieu, Ouédraogo Pouraogo, Zoundi Christian, Zerbo Jean-Louis & Ouattara Frédéric · Current Journal of Applied Science and Technology · 2026

Ionospheric scintillation is a phenomenon of rapid and irregular fluctuations in the intensity of radiofrequency signals passing through the ionosphere. It generally arises from interactions between GNSS signals and irregularities in the ionospheric plasma. These interactions can...

Variation of the Critical Frequency of the Ionospheric F2 Layer during Moderate Geomagnetic Conditions: A Study Using Data from the Ouagadougou Ionosonde Station Across Solar Cycles 21 and 22

DIABATE Abidina, SAWADOGO Wambi Emmanuel, GUIBULA Karim & Ouattara Frédéric · Current Journal of Applied Science and Technology · 2025

This study investigates the variations in the critical frequency of the F2 layer (foF2) at the Ouagadougou ionosonde station during moderate geomagnetic activities, focusing on corotating and magnetic cloud events across the minimum and maximum phases of solar cycles 21 and 22. T...
