<br>
We invite abstracts for the C1.1 session being organized at 46<sup>th</sup> COSPAR scientific assembly at Florence, Italy during 01-09 August 2026. The details of the session are given below.<br>
<br><strong>Session C1.1:</strong> Recent Advances in Equatorial, Low- and Mid-Latitude Mesosphere, Thermosphere, and Ionosphere Studies<br><br><strong>Description:</strong> Dynamic processes taking place in the mesosphere, lower thermosphere and ionosphere are always intriguing to the scientific community. Ever increasing ground and space based experiments are providing large database on the MLT region, and opening up new avenues to employ advanced Artificial Intelligence (AI) and Machine Learning (ML) techniques to understand and simulate various physical processes taking place in these regions.<br><br>
Papers are invited for a session on the recent advances in the field of the equatorial, low- and mid-latitude mesosphere, thermosphere, and ionosphere from observational (ground-based and space-borne), theoretical and simulation studies. Contributions related to all aspects of these areas are welcome. Topics include but not limited to: MLT region; the response of the thermosphere- ionosphere system to forcing from above and below; equatorial electrodynamic processes; coupling between mid-, low- and equatorial latitude regions; space weather events (especially the May 2024 event); magnetosphere-ionosphere coupling; Ionospheric response to SSW; ionospheric irregularities and scintillations; latitudinal and/or longitudinal variability; ionosphere F-layer stratification; data-assimilation studies; modelling through AI/ML; advanced space and ground-based experiments, tomography. The session will include both solicited and contributed (oral and poster) papers.<br><br>
Last date for submission of abstracts: <strong>13 February 2026</strong><br><br>
