<br>
Dear Colleagues,<br>
<br>
The joint scientific assembly of IAGA / IASPEI is scheduled to take place at Lisbon, Portugal during 31 August to 5 September 2025. We invite abstracts for the following session during this joint scientific assembly.<br>
<br>
<br><strong>Session A14:</strong> Advances in Mid-Latitude, Low-Latitude and Equatorial Aeronomy<br>
<br><strong>Description:</strong> Papers are invited for a symposium on the recent developments in the field of equatorial, low-latitude and mid-latitude aeronomy from observational (ground-based and space-borne), theoretical and simulation studies. The Equatorial Electrojet, Equatorial Ionization Anomaly (EIA), Equatorial Spread-F (ESF)/plasma bubbles, multiple F-layer stratifications, Solar quiet current system, ionospheric disturbances induced by geomagnetic storms (including its local magnetic effects), SSWs, present a strong daily, day-to-day, and seasonal variability, mainly caused by the ionospheric electrodynamics, thermospheric winds and wave actions (gravity waves, tides, planetary waves, TIDs and MSTIDs). Recent multi-instrument and multi-site observations, satellite borne experiments, as well as theoretical and simulation investigations have advanced our understanding of these phenomena, during both quiet and disturbed space weather conditions including geomagnetic storms, the recent storm of 10 May 2024, sub-storms, solar flares, solar eclipses, sudden stratospheric warmings and different meteorological events. The objective of this symposium is to bring together the experimentalists and theoreticians to survey the latest results, examine new ideas and concepts, and to pave the way for future directions in equatorial and low-latitude research. The session will include both solicited and contributed (oral and poster) papers.<br>
