Although much progress has been made in the study of ionospheric space weather in the last decade, many gaps remain in our understanding of some of the fundamental physical processes and the related impact on technologies, such as the performance and availability of satellite-based navigation and communication systems. In this session, we invite papers about recent progress and current understanding of the physical processes of ionospheric density structuring and the related impact on technologies. Observational, modeling, and theoretical studies are all encouraged. </font></section></section><p style="margin-right: 1in; margin-left: 0in; margin-bottom: 12pt;" class=""><font face="Calibri" class="">You can use the link below to submit an abstract to this session:<br class=""></font><a href="https://agu.confex.com/agu/fm18/prelim.cgi/Session/47371" class="">https://agu.confex.com/agu/fm18/prelim.cgi/Session/47371</a></p><p style="margin-right: 1in; margin-left: 0in; margin-bottom: 12pt;" class=""><font face="Calibri" class="">Best regards,</font></p><div class=""><span style="font-family: Calibri;" class="">SA012 conveners: </span><span style="font-family: Calibri;" class="">Shasha Zou, </span><span style="font-family: Calibri;" class="">Jade Morton, </span><span style="font-family: Calibri;" class="">Seebany Datta-Barua</span></div></body></html>
