CEDAR email: CEDAR/GEM Session: New Perspectives on Whole-Atmosphere Coupling and MIT System Impacts

[Xian Lu]

Dear Colleagues,

We would like to invite your participation in the joint CEDAR/GEM Session: New Perspectives on Whole-Atmosphere Coupling and MIT System Impacts

Session Description:
Coupling across atmospheric layers is a fundamental driver of variability in the Magnetosphere-Ionosphere-Thermosphere (MIT) system, shaping both space weather and long-term upper atmospheric trends. The MIT system is highly responsive to external drivers, including variations in solar irradiance, solar wind-interplanetary coupling, as well as internal fluctuations from the lower atmosphere. Sudden Stratospheric Warmings are well-established drivers of upper atmospheric variability, but growing evidence shows that other episodic disturbances—including volcanic eruptions and tropospheric convection—can also generate large-scale effects, influencing plasma outflows, neutral-plasma interactions, and storm-time responses. More broadly, lower atmospheric variability—including tides, gravity waves, planetary waves, Kelvin waves, and other disturbances—can modulate plasma transport, ionospheric structuring, and even magnetospheric electrodynamics. Superimposed on these terrestrial-induced variations are abrupt disturbances triggered by solar flares and geomagnetic perturbations in the form of particle precipitation, plasma outflow, field-aligned currents, heat flux, etc. 

The CEDAR and GEM communities are uniquely positioned to collaboratively study this whole-atmosphere coupling and its impacts on the MIT system. This session welcomes observational, theoretical, and modeling studies that investigate MIT coupling across spatial and temporal scales, with emphasis on new insights from multi-instrument satellite missions (e.g., ICON, GOLD, COSMIC-2, MMS, THEMIS, Van Allen Probes), ground-based networks, and state-of-the-art models (e.g., WACCM-X, MAGE, TIEGCM, SAMI3). Contributions addressing the roles of atmospheric waves and geomagnetic activity in space weather, energy transfer mechanisms, electrodynamic feedback, and interhemispheric asymmetries are particularly encouraged. The theme of this session closely aligns with the NSF/ANSWERS solicitation to support collaborative research on space physics
