ionosphere-thermosphere (IT) region is strongly driven by the lower atmosphere as well as by the sun and solar wind/magnetosphere interaction. However, the strong spatio-temporal cross-scale, cross-regime coupling in this region are poorly understood due to
lack of critical measurements. To improve this situation, we must develop a coordinated international “Ionosphere-Thermosphere-Mesosphere Great Observatory” (ITM-GO) effort, consisting of coordinated comprehensive ground-based and space-based observations
alongside advanced theory/modeling efforts.</span></span><span class="apple-converted-space"><span style="font-family:"Arial",sans-serif;background:white"><o:p></o:p></span></span></p>
<p class="MsoNormal" style="text-align:justify;background:white"><span class="apple-converted-space"><span style="font-family:"Arial",sans-serif;color:black;background:white">The Geospace Dynamics Constellation (GDC) mission, a critical ITM-GO element, will
provide the first quantitative assessment of the global IT responses to solar and magnetospheric inputs. The concurrent Dynamical Neutral Atmosphere-Ionosphere Coupling (DYNAMIC) mission will observe critically important dynamics in the mesosphere and lower
thermosphere and the IT forcing by the lower atmosphere. This session calls for presentations on research investigations that will be enabled by GDC and DYNAMIC. Strategies for coordinated ground- and space-based observational and modeling investigations are
also encouraged.</span></span><span style="font-family:"Times New Roman",serif"><o:p></o:p></span></p>
