SA42B:
Generation Mechanisms of Ion Upflow/Outflow and Suprathermal Particles in the Coupled Magnetosphere-Ionosphere System I

Submit an Abstract to this Session



Session ID#: 32293

Session Description:
The Earth’s ionosphere is a significant plasma source for the magnetosphere and strongly influence the geospace dynamics. Hence, understanding of the strength and dynamics of the ion upflow/outflow particles up into the magnetosphere is of critical importance to understanding how the magnetosphere is populated and influenced by these initially low-energy particles. In particular, suprathermal particles are ubiquitous in the auroral and subauroral geospace particularly during active periods. Their role in the ion upflow/outflow events and heating of ionospheric plasma has been proposed but not very well understood.

In this session, we invite papers that attempt to improve understanding (1) on the influences of low-altitude ionosphere-thermosphere conditions on ion upflow/outflow into the magnetosphere, (2) on the energization processes of the ion upflow/outflow population for the polar wind, and (3) generation mechanisms of suprathermal particles and their role in ion upflow/outflow events. Papers on data, theory, and modeling are invited.
