The interplay of these energization processes raises ionospheric plasma to higher altitudes and sometimes enables the escape of ions into the magnetosphere, where they contribute to plasma populations and affect magnetospheric dynamics. Over geologic timescales, ion escape can modify atmospheric density and composition. While a number of instruments have observed upflow and outflow processes in the aurora and polar cap, recent advances in theory and modeling of ion upflow and escape processes raise new questions and require new constraints. </span><o:p class=""></o:p></div><p class="MsoNormal" style="margin: 0in 0in 6pt; font-family: Calibri, sans-serif; background-color: white;"><span style="font-size: 10.5pt; font-family: Arial, sans-serif; color: rgb(38, 38, 38);" class="">This session will focus on analysis of satellite, rocket, and ground-based observations and future observations that are needed to shed light on the processes of ion escape, as well as theory, modeling, and validation of ionospheric energization and escape processes at Earth and other planets.</span><o:p class=""></o:p></p><div style="margin: 0in 0in 0.0001pt; font-family: Calibri, sans-serif;" class=""> <o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-family: Calibri, sans-serif;" class=""><a href="https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fagu.confex.com%2Fagu%2Ffm19%2Fprelim.cgi%2FSession%2F79515&data=01%7C01%7Croger.varney%40sri.com%7C53c50ab4e3d0424df17408d70eeafa0c%7C40779d3379c44626b8bf140c4d5e9075%7C1&sdata=JzVtCI4AhLFP7FgicZqfLsOf7hVaOBqSlM894UxT9Es%3D&reserved=0" style="color: rgb(149, 79, 114);" class="">https://agu.confex.com/agu/fm19/prelim.cgi/Session/79515</a><o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-family: Calibri, sans-serif;" class=""> <o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-family: Calibri, sans-serif;" class="">We hope you will consider submitting your talk or poster to this session.<o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-family: Calibri, sans-serif;" class=""> <o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-family: Calibri, sans-serif;" class="">Sincerely,<o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-family: Calibri, sans-serif;" class="">Katherine Garcia-Sage (NASA/GSFC), Roger Varney (SRI), and Shasha Zou (U of Michigan)<o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class=""><br class=""></span></div><div style="margin: 0in 0in 0.0001pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class=""> </span></div></body></html>
