Session ID#: 17301

Session Description:
The Earth’s ionosphere is a significant source of plasma to the magnetosphere and a strong influence on the dynamics of the geospace environment. The ionospheric source is contributing plasma to the plasmasphere, the plasma sheet, and the ring current and through wave-particle interactions is playing a major role in the formation and dynamics of the radiation belts. 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 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) on the effects of ion outflow population on magnetospheric dynamics. Papers on data, theory, and modeling are invited.
