Abstract

The main purpose of the study is to determine the parameters used to identify the variability of the ionospheric region in Malaysia. In order to contribute to the development of a model of ionospheric variability, the behavior of the ionospheric critical frequency, foF2 was analyzed on diurnal variation basis at different solar activity conditions and during earthquake occurrence. The Canadian Advanced Digital Ionosonde (CADI) is a low cost, flexible, full featured ionosonde ideal for both routine ionospheric monitoring and research. The ionosonde uses basic radar techniques to detect the critical frequency of the ionosphere. Simulation using Matlab was utilized to fit the critical frequency of the ionosphere. The observation data was obtained from the Ionogram that has been stationed in WARAS Centre, UTHM. Overall, the solar activity can affects the value of critical frequency at the daytime more than during night time. Other than that, the relationship between the Earth’s movement and the variation of the critical frequency in the ionosonde data can be determined.
