International Colloquium on Equatorial and Low-Latitude Ionosphere

September 19-23, 2022

Gaining better understanding of the dynamics of the equatorial and low latitude ionosphere has become an object of global concern more than ever. Equatorial region, also known as the low latitude region refers to the region within ± 20° on either side of the geomagnetic equator.  The region is characterized with much complexities and high level of dynamics which result in phenomena such as spread F, ionospheric anomaly, equatorial electrojet, equatorial plasma fountain, etc. The impact of such phenomena on telecommunications, navigation, satellite operations, and other space-based technologies has made the region a point of international collaborative focus in scientific research. Installation of new and diverse forms of ionospheric equipment is providing avenue to reveal more information about the equatorial region which were previously not known, especially in the African sector. In addition, there are several experimental satellites with focus on equatorial space environment.

Main features
Just like the previous three editions of the Colloquium, this hybrid edition shall feature a combination of tutorials, seminars, conference and hands-on training on every aspect of research and techniques bordering on the dynamics of equatorial and low latitude ionosphere as well as space weather.

The Colloquium shall also include discussions on HF Radars, and on phenomena such as equatorial ionosphere, equatorial electrojet, equatorial ionospheric anomaly, geomagnetic disturbances, geomagnetically induced currents, solar-terrestrial relations, stratospheric warming, space weather, theory and modeling of ionospheric scintillation and irregularities, etc.

This fourth edition will also present the status of the Nigerian Bowen Equatorial Aeronomy Radar being developed at the Bowen University, Nigeria, and highlight the prospect of the facility as a global infrastructure for ionospheric research.

This Colloquium shall offer opportunities for presentation of standard contributions (oral and poster), delivery of invited papers by distinguished scientists with the intention of educating young scientists, as well as exhibition of space-dependent technologies and measurement systems relevant to ionospheric studies. The forum shall serve as an effective meeting point for scientists, policy makers, students and designers of space-dependent technologies.

Working language
The working language of the Colloquium is English.
