<p class="MsoNormal" style="text-align:justify">The ionosphere, thermosphere and Mesosphere (ITM) system variations are strongly driven by energy, momentum and particle inputs from the solar EUV radiation, solar wind, magnetosphere and lower atmosphere, photo-chemical
processes as well as ion-neutral coupling. The global ITM response also depends on the temporal and spatial scales of the drivers and has significant feedback effects on the entire coupled geospace. The ITM response or variations have significant impacts on
the operation (such as LEO satellite drag, radio scintillation, <span style="mso-fareast-language:ZH-CN">
and </span>ground induced current, etc.). Understanding the interplay among the drivers, responses and feedbacks, would require not only extensive global observations of these drivers and state parameters of various spatial and temporal scales, but also 4-Dimensional
global physics-based models to properly interpret these observations. Today, the combined observations from the continuing space (e.g., TIMED, COSMIC, etc.) and groundbased assets, with those taken by the upcoming international (e.g., U.S. NASA’s ICON, GOLD
and Taiwan NSPO’s COSMIC2) space missions are expected to significantly improve the characterization of the ITM system variabilities. In addition, simulations by advanced models can provide further insights into our understanding of the ITM response. Here
we propose this AOGS session to prepare ourselves for this upcoming opportunity by sharing knowledge and capabilities, stimulating scientific discussions, and fostering joint research opportunities among community scientists. We welcome all contributions
based on analysis of data from in situ or remote sensing measurement of space and ground and from model studies (physics based, empirical, and assimilation) on related ITM topics under different solar and geomagnetic conditions (storms, non-storms, periodic
variations, and lower atmosphere, etc.). Future plans of new measurements and capabilities are also welcome.
