<p>Dear colleagues<br>
</p>
<p><br>
</p>
<p>We would like to invite your participation in the 2020 Virtual CEDAR meeting on "Geospace storm dynamics in the upper atmosphere and ionospheric density gradients". <br>
</p>
<p><br>
</p>
<p>This session is devoted to understanding the fundamental storm-time dynamics in the ionosphere and thermosphere with focus on ionospheric density gradients. Of particular interest to this session are storm enhanced density, midlatitude ionospheric trough,
polar tongue of ionization, polar patches, and large scale traveling ionospheric disturbances. The presentations will characterize these storm-time features and/or address physical processes leading to their formation and evolution. The session consists of ~10
talks each for 10-15 min with presentation and discussion. <br>
</p>
<div><br>
</div>
<p>The session is open, without registration, to general members of the CEDAR community, including the international research community. <br>
<br>
</p>
<p><strong>Time</strong>: <span style="font-size: 12pt;">Friday, June 26; 08:30-11:00AM MDT [10:30am – 1:00pm EDT or
<strong>14:30-16:</strong></span><span style="font-size: 12pt;"><strong>00 UTC</strong></span><span style="font-size: 12pt;">]</span></p>
