The stratosphere, mesosphere, thermosphere, and ionosphere are a region of great interest that marks the transition between the neutral dynamic processes of the middle atmosphere and ionized processes in the upper atmosphere/ionosphere. The variability of composition and structure in this region provides insights into the mechanisms of the coupling from the lower to the upper atmosphere and their responses to influences of solar activity from above and tropospheric activity from below. Many layering phenomena can provide tracers for studying the middle/upper atmosphere and ionosphere, such as sporadic E layers, metal layers (Fe, Na, Mg, K, Ca, and Mg), noctilucent clouds, and their interaction with wave activities (gravity waves, tides, and planetary waves, etc).
Despite significant advancements in our knowledge of the middle/upper atmosphere and ionosphere over the past ten years, it is still difficult to forecast changes in ionospheric irregularities and dynamic processes in the Earth’s upper atmosphere. New results of observations and simulations of layering phenomena in the middle/upper atmosphere and ionosphere can advance our knowledge of dynamics, chemistry, long-term change, and vertical coupling. In this Research Topic, we hope to study the changes in the upper atmosphere and ionosphere on different timescales from new observations of satellite/ground-based instruments and numerical modeling, and thus we can advance our understanding of the mechanisms of dynamical and chemical processes.
We invite you to submit your research for publication on this Research Topic. A range of article types is welcome, including original research articles and review articles.
Examples of such topics in this research topic include, but are not limited to:
(1) Ionospheric irregularities sporadic E layer and ion-neutral coupling between E and F region.
(2) Mesospheric phenomena such as the neutral metal layers, noctilucent clouds (NLCs), polar mesospheric clouds (PMCs), and polar mesospheric summer echoes (PMSEs), etc.
(3) Influence of tides, gravity waves, and planetary waves on the coupling of the atmosphere and ionosphere.
(4) Influence of tropospheric activity and sudden stratosphere warming on the atmosphere and ionosphere.
(5) Influence of solar and geomagnetic activities on the atmosphere and ionosphere.
