P021:
Ionospheric Outflow From Earth and Other Terrestrial Planets





Session ID#: 26997

Session Description:
On every terrestrial planet with an atmosphere, EUV radiation creates ions in the upper atmosphere that may flow upward. If the ions are energized enough, they can escape the gravitational potential. Depending on the presence and nature of the planetary magnetic field, there may be many different mechanisms causing ion upflow and outflow, like particle precipitation, ambipolar electric fields driving a polar or planetary wind, wave-particle interactions, direct solar wind-ionosphere interactions, ion pick-up, etc. These escaping ions contribute to the atmospheric erosion. Upflowing ions can be blocked by an induced magnetosphere or trapped inside an intrinsic magnetosphere. They may affect their plasma environment and even alter the dynamics of the magnetosphere. This session invites contributions concerning all the processes controlling ionospheric ion upflow and outflow on Earth, Venus, and Mars, and their possible implications. Submissions comparing the processes at different planets, similarities and differences, are also encouraged.
