<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif"><span style="font-size:12pt;line-height:107%">In the last few years several
satellite missions were launched which provides the scientific community with a
wealth of observations of the thermosphere-ionosphere system. COSMIC 2 is a
cluster of 6 satellites carrying GNSS receivers, tri-band beacons, and ion
velocity meters (IVM) bringing together ionospheric TEC, scintillation, and ion
drift observations. GOLD is an UV imager on a geo-synchronous satellite
providing constant observations of the ionosphere and thermosphere over the
American sector. ICON covers the low latitude region and provides neutral wind,
ion drift, and UV observations.  In
addition, data from ground observations are probing the ionosphere-thermosphere
system and are ideal to capture temporal variation and combined in networks
give information about spatial scales. This includes observations of plasma
characteristics, neutral wind, magnetic field variations etc. </span></p>

we solicit presentations of new results from these missions highlighting the
synergistic effect by combining ground, space-based observation, and/or
modeling.  The goal of this session is to
foster collaborations for increased scientific returns.  </span></b></p>
