CEDAR email: EGU2023: Call for Abstracts in Session ST3.5 - Dynamics, Chemistry, and Coupling in the MLT Regions

[Khadka, Sovit]

Dear CEDAR Community,

You are cordially invited to submit abstracts to our 2023 EGU General
Assembly session (ST3.5) - Dynamics, Chemistry, and Coupling in the MLT
Regions. The 2023 EGU General Assembly will be held on 23–28 April 2023,
both on-site in Vienna, Austria, and virtually.

         *****Session Details*****
Session Title: Dynamics, Chemistry, and Coupling in the MLT Regions
Session Group: Ionosphere and Thermosphere (ST3)
Session Link: https://meetingorganizer.copernicus.org/EGU23/session/46351
Convener: Sovit Khadka, New Jersey Institute of Technology, USA
Co-Conveners: Claudia Stolle, Leibniz Institute of Atmospheric Physics,
Germany
                         Tatsuhiro Yokoyama, Kyoto University, Japan
                         David Themens, University of Birmingham, UK
                         Andrew Akala, University of Lagos, Nigeria


*Session Description:*
The Earth's mesosphere and lower thermosphere (MLT) region is a great
platform to study ionospheric dynamics, disturbances, eddy mixing, and
controlling parameters. This transition region is sandwiched between the
lower and upper atmosphere which is strongly driven by the forcing from
both the above (e.g., solar and magnetospheric inputs) and below (e.g.,
gravity waves and atmospheric tides). The thermal structure of the MLT
region is controlled by numerous sources and sinks of energy including
solar radiation, chemical, and dynamical processes. Solar atmospheric tides
related to global-scale variations of winds and waves are responsible for
the coupling of the lower and upper layers of the atmosphere. During the
coupling process, the precipitation of energetic particles into the MLT
region also has a great influence on the vertical profiles of the
temperatures, chemistry, and dynamics of the upper atmosphere. This is a
suitable forum/time to encourage the science community to present, discuss,
update, and improve our understanding of dynamics, chemistry, and coupling
in the MLT region that ultimately affect the electrodynamics of the whole
coupled geospace environment. This session invites presentations on
scientific work related to various experimental/observational techniques,
numerical and empirical modeling, and theoretical analyses on the dynamics,
chemistry, and coupling processes in the altitude range of ~ 60 km to 180
km of the MLT regions.

We look forward to your contribution to our EGU General Assembly session.
Please note that the abstract submission deadline is *Tuesday, 10 January
2023 at 13:00 CET*.

Thank you.

Sincerely,
Sovit Khadka, Claudia Stolle, Tatsuhiro Yokoyama, David Themens, and Andrew
Akala
