Dear colleagues<br>
<br>
We welcome your submission to the session "<b>SM015: Ionospheric
outflow on terrestrial planets</b>" at AGU 2015.<br>
<br>
Description:<br>
<b>Ionospheric outflow on terrestrial planets</b><i><br>
</i>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.<br>
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.<br>
This session invites contributions concerning all the processes
controlling ionospheric ion upflow and outflow on Earth, Venus, and
Mars, and their possible implications.<br>
