*Session Description:*</font></pre><pre><p style="color:rgb(0,0,0);margin:0.4em 0px 0.5em;line-height:1.5em;white-space:normal"><font face="arial, helvetica, sans-serif">The ionospheric electrodynamo couples the lower atmosphere to the upper atmosphere at middle and low latitudes. In recent years observations and numerical simulations indicate that the lower atmospheric forcing can have measurable effects on the thermosphere-ionosphere system. While most studies focused on the daytime when the E-region wind dynamo dominates, there are effects in the F-region e.g., F-region wind dynamo, gravity and plasma pressure pressure gradient forces, which might have to be considered when interpreting and understanding satellite data and the TI system. Observations of night-time ion drift illustrate that the ionosphere and its electrodynamics is highly variable. Even at dawn and dusk the low-latitude and equatorial ion drift variations reflect the complexity of the system with the sudden changes in ionization and the wind system.</font></p><h3 style="color:rgb(0,0,0);background-image:none;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;margin:0px 0px 0.3em;overflow:hidden;padding-top:0.5em;padding-bottom:0.17em;border-bottom:none;white-space:normal"><span class="gmail-mw-headline" id="gmail-Agenda"><font face="arial, helvetica, sans-serif" size="2">Agenda</font></span></h3><ul style="color:rgb(0,0,0);line-height:1.5em;list-style-type:square;margin:0.3em 0px 0px 1.6em;padding:0px;white-space:normal"><li style="margin-bottom:0.1em"><font face="arial, helvetica, sans-serif">Rod Heelis (UTD) - Introduction to ionospheric electrodynamics </font></li></ul><ul style="color:rgb(0,0,0);line-height:1.5em;list-style-type:square;margin:0.3em 0px 0px 1.6em;padding:0px;white-space:normal"><li style="margin-bottom:0.1em"><font face="arial, helvetica, sans-serif">Tim Fuller-Rowell (CIRES/NOAA)- Electrodynamics - past, present, future </font></li></ul><ul style="color:rgb(0,0,0);line-height:1.5em;list-style-type:square;margin:0.3em 0px 0px 1.6em;padding:0px;white-space:normal"><li style="margin-bottom:0.1em"><font face="arial, helvetica, sans-serif">Dave Hysell (Cornell) - 3-dimensional electrodynamics </font></li></ul><ul style="color:rgb(0,0,0);line-height:1.5em;list-style-type:square;margin:0.3em 0px 0px 1.6em;padding:0px;white-space:normal"><li style="margin-bottom:0.1em"><font face="arial, helvetica, sans-serif">Nick Pedatella (NCAR) - Electrodynamics and the TI system </font></li></ul><ul style="color:rgb(0,0,0);line-height:1.5em;list-style-type:square;margin:0.3em 0px 0px 1.6em;padding:0px;white-space:normal"><li style="margin-bottom:0.1em"><font face="arial, helvetica, sans-serif">Scott England (VT) - Upcoming missions: What can be learned about the electrodynamics? </font></li></ul><ul style="color:rgb(0,0,0);line-height:1.5em;list-style-type:square;margin:0.3em 0px 0px 1.6em;padding:0px;white-space:normal"><li style="margin-bottom:0.1em"><font face="arial, helvetica, sans-serif">Naomi Maruyama (CIRES/NOAA) - Storm effects at low latitudes</font></li></ul><ul style="color:rgb(0,0,0);line-height:1.5em;list-style-type:square;margin:0.3em 0px 0px 1.6em;padding:0px;white-space:normal"><li style="margin-bottom:0.1em"><font face="arial, helvetica, sans-serif">Joe Huba (NRL) Toward a global electrodynamic model of the ionosphere</font></li></ul><div style="color:rgb(0,0,0)"><font face="arial, helvetica, sans-serif"><span style="white-space:normal"><br></span></font></div><div><pre style="color:rgb(0,0,0)"><font face="arial, helvetica, sans-serif">More information on the session can be found at</font></pre><pre><font color="#000000"><b><font face="arial, helvetica, sans-serif"><a href="https://cedarweb.vsp.ucar.edu/wiki/index.php/2017_Workshop:Agenda">https://cedarweb.vsp.ucar.edu/wiki/index.php/2017_Workshop:Agenda</a></font></b><br></font></pre><pre><font color="#000000"><font face="arial, helvetica, sans-serif">Regards,</font></font></pre><pre><font color="#000000"><font face="arial, helvetica, sans-serif">Astrid Maute, Tzu-Wei Fang, Fabiano Rodrigues</font></font></pre><pre><font color="#000000"><b><font face="arial, helvetica, sans-serif"><br></font></b></font></pre></div></pre>
