Could you distribute this to the CEDAR e-mail list?
Thanks in advance
We welcome your submission to the session "*SM015: Ionospheric outflow
on terrestrial planets*" at AGU 2015.
*Ionospheric outflow on terrestrial planets*/
/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 in auroral regions, ambipolar electric fields driving a
polar wind, wave-particle interactions, direct solar wind-ionosphere
A fraction of these outflowing ions escapes into interplanetary space,
so that they contribute to the erosion of the atmosphere; another
fraction of ions may remain trapped inside the magnetosphere for some
time, where they can affect the magnetospheric dynamics, especially for
heavy ions, like O⁺; yet another fraction may return to the ionosphere.
This session invites contributions concerning all the processes
controlling ionospheric ion upflow and outflow on Earth, Venus, and
Mars, and their possible implications.
