This international session focuses on physical/chemical processes occurring in the mesosphere, thermosphere, and ionosphere (MTI) from both the poles to the equatorial region. Both quiet and disturbed states in response to lower atmospheric forcing or solar forcing are important for understanding the MTI system and its coupling to other regions. We invite presentations of observations and observational concepts with ground-based and/or space-borne instruments, theoretical studies, numerical simulations, and development of data analysis systems for various kinds of temporal and spatial variations in MTI system.</div><div class=""><br class=""></div><div class="">Further session and submission information can be found at: <a href="http://www.asiaoceania.org/aogs2018/public.asp?page=sessionList.htm" class="">http://www.asiaoceania.org/aogs2018/public.asp?page=sessionList.htm</a> .
