The Ionosphere-Thermosphere-Magnetosphere (ITM) system responds dynamically to both terrestrial weather from below and space weather from above. This session explores the relative roles and interactions of atmospheric waves—such as tides, planetary waves, and gravity waves—and external drivers, including solar irradiance, solar wind, and geomagnetic activity, in shaping global ITM variability. Special emphasis is placed on disturbances from sudden stratospheric warmings, volcanic eruptions, tropospheric convection, and geomagnetic storms. We invite observational, theoretical, and modeling studies that investigate coupling across spatial and temporal scales, with contributions from satellite missions (e.g., ICON, GOLD, AWE, COSMIC-2, MMS), ground-based networks (e.g., SuperDARN, GNSS, ISR, Fabry-Perot interferometers, magnetometer arrays), and advanced models (e.g., WACCM-X, MAGE, TIEGCM, SAMI3). This session encourages cross-disciplinary collaboration to improve understanding of whole-atmosphere coupling and its impact on space weather, electrodynamics, and thermospheric structure.
