Abstract
The variability of solar activity plays an important role in controlling the chemical reactions and physical processes in the ionosphere. To improve our understanding of the characteristics of the ionosphere over Malaysia, a study of the effects of solar activity on the ionosphere is required. This paper focuses on the variations in the ionosphere as a result of solar activity. Variations in the ionosphere are divided into (1) critical frequency profile, (2) maximum usable frequency and minimum frequency, (3) variations of TEC to solar activity, (4) ionospheric delay, (5) scintillation and (6) the equatorial plasma bubble. The paper also provide new information towards a comprehensive explanation of the basis processes involved in improving the prediction capability of the ionospheric model and its related applications.
