- Abstract
The results from previous studies on ionospheric variability have shown that the ionosphere, especially over the equatorial and low latitude region undergoes sporadic changes in the electron density structure which causes harmful effects to high frequency satellite radio signals passing through the region. This paper attempts to review past work on the phenomena dominating the equatorial and low latitude ionosphere and to highlight yet unsolved problems. There are several attempts by past scientist to study and understand the dynamic structure of the ionosphere across different latitudes and longitudes using ground-based observations, in-situ satellite measurements and ionospheric models. These scientists have come up with reports of different anomalous phenomena dominating the equatorial and low latitude region. Some phenomena like the spread-F, equatorial electrojet current and equatorial anomaly have been highlighted. Apart from all the interesting reports so far documented, there are yet some grey areas that still needs further research. For example, the ionosphere-thermosphere coupling at equatorial and low latitude during extreme solar event and earthquake disaster is still a subject of major concern.
