Science topics include but are not limited to 1) multi-step vertical wave coupling mechanisms and their impacts on the general circulation, thermal structures, and constituents, 2) horizontal coupling among the tropical, mid-latitude, and polar regions and their impacts on the long- and short-term variability, 3) the atmosphere-ionosphere-magnetosphere coupling and impacts on compositions and thermodynamics, 4) the responses of mesosphere-thermosphere-ionosphere system to geomagnetic and solar activities, and 5) the transport of global cosmic dust and minor species and wave-induced fluxes. This session aims to bridge the neutral atmosphere research with the ionosphere and magnetosphere research, and stimulate new science collaborations among experimentalists, theoreticians, and modelers, seeking new science paths.</font></span></div><div class=""><font color="#000000" face="Calibri, sans-serif" class=""><span style="caret-color: rgb(0, 0, 0); font-size: 14.666666984558105px;" class=""><br class=""></span></font></div><div class=""><div class=""><span style="font-family: Calibri; font-size: 15px;" class=""><b class="">Link to submit an abstract:</b></span></div><div class=""><font face="Calibri" class=""><span style="font-size: 15px;" class=""><a href="https://agu.confex.com/agu/fm20/prelim.cgi/Session/105274" class="">https://agu.confex.com/agu/fm20/prelim.cgi/Session/105274</a></span></font></div></div><div class=""><br class=""></div><div class=""><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: Calibri, sans-serif; font-size: 14.666666984558105px;" class="">Abstract Deadline: July 29 </span></div><div class=""><font face="Calibri" style="font-size: 15px;" class=""><br class=""></font></div><div class=""><font face="Calibri" class=""><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-size: 15px;" class="">We look forward to seeing your submission and your participation in this session in December!</span></font></div><div class=""><font style="font-size: 15px;" class=""><br class=""></font></div><div class=""><font style="font-size: 15px;" class=""><br class=""></font></div><div class=""><font color="#000000" face="Calibri" class=""><span style="caret-color: rgb(0, 0, 0); font-size: 15px;" class="">Best regards,</span></font></div></div><div class=""><font color="#000000" face="Calibri" class=""><span style="caret-color: rgb(0, 0, 0); font-size: 15px;" class="">Xinzhao Chu, Xian Lu, Zhonghua Xu</span></font></div><div class=""><font color="#000000" face="Calibri" class=""><span style="caret-color: rgb(0, 0, 0); font-size: 15px;" class=""><a href="mailto:xinzhao.chu@colorado.edu" class="">xinzhao.chu@colorado.edu</a></span></font></div><div class=""><font color="#000000" face="Calibri" class=""><span style="caret-color: rgb(0, 0, 0); font-size: 15px;" class=""><a href="mailto:xianl@g.clemson.edu" class="">xianl@g.clemson.edu</a></span></font></div><div class=""><font color="#000000" face="Calibri" class=""><span style="font-size: 15px;" class=""><a href="mailto:zxu77@vt.edu" class="">zxu77@vt.edu</a></span></font></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div></body></html>
