Dear colleagues

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 
interactions, etc.
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.
