International Colloquium

About the Colloquium

International Colloquium on Equatorial and Low Latitude Ionosphere (ICELLI) is an annual capacity-building workshop geared towards understanding of the Sun and its impact on space weather; the dynamics of the equatorial ionosphere, its complexities and high level of dynamics which results in phenomena such as the spread F, ionospheric anomaly, equatorial electrojet, equatorial plasma fountain, etc; and how space weather impact on telecommunications, Navigation, satellite operations, and other space-based technologies. In 2019, the Colloquium metamorphosed from a summer school-like programme tagged International School on Equatorial and Low Latitude Ionosphere (ISELLI) which was held in Abuja and Ota, Nigeria in 2015 and 2017 respectively. This year’s colloquium, tagged ‘ICELLI 2024,’ would be the 8th edition of this capacity-building gathering in Nigeria.

The equatorial region, also known as the low latitude region, refers to the region within ± 20° on either side of the geomagnetic equator. The great effect of the equatorial ionosphere on space-based technologies, due to its associated complexities and dynamics, has made the region a point of international collaborative focus in scientific research

The activity is planned to run for a period of 5 days. The program of the Colloquium includes discussions of the rather wide range of phenomena, such as equatorial ionosphere, equatorial electrojet, equatorial ionospheric anomaly, geomagnetic disturbances, geomagnetically induced currents, solar-terrestrial relations, stratospheric warming, space weather,  theory and modelling of ionospheric scintillation and irregularities, utilisation of equatorial orbital plane for satellite technology, presentation of results from different and novel techniques for probing the equatorial ionosphere etc.

This edition shall like the past editions feature a composition of tutorials, seminars, conferences 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.

This year’s edition shall have 2 days dedicated to emerging topics of interest such as applications of Artificial Intelligence AI, Machine Learning, open-source programming languages and non-linear tools towards understanding and predictability of complex space weather processes for effective operational systems.

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