On the Contribution of E- and D-Layer to Weak Geomagnetic Storm Events in South Africa

Abstract

Data from five ionosonde in Southern Africa have been analyzed to better appreciate the contributions of the E- and D-layers of the ionosphere in this region to weak geomagnetic storms. This attempt to quantify the exact contributions of the D and E-layers to weak geomagnetic storms during period of relatively quiet Sun has never been done in this region before. The results suggest that the E-layers contribute more than the D-layers.
