Session Description:
The presence of heavy ions in the near-Earth environment has a profound impact on the global magnetosphere-ionosphere dynamics, especially during times of increased geomagnetic activity. Heavy ions affect the structure and properties of the current sheet, the mass loading of the magnetosphere, the reconnection processes, and can modify local properties of the plasma. The presence of heavy ions influences plasma wave properties such as propagation and wave frequency, which dependent on the mass composition. Tracking heavy ions provides clues regarding the generalized ionospheric outflow process and its role in controlling the ionosphere-magnetosphere system. Knowledge of heavy ion contribution to the near-Earth plasma together with their differential transport throughout the magnetosphere system, provides a unique insight into the connection between the macro-scale dynamics and micro-scale processes that govern this region. This session welcomes presentations on research pertaining to impact of heavy ions on magnetospheric processes, including observational, theoretical and/or numerical studies.
