CEDAR email: First Call for Abstracts: COSPAR-26 Scientific Assembly middle atmosphere sessions

[Robin Wing]

Dear Colleague,

 

We would like to invite you to contribute to the COSPAR-26 Scientific
Assembly middle atmosphere sessions (C2).  The conference will take place in
Florence, Italy, from 1-9 August 2026.

 

COSPAR-26-C2.1: Gravity Waves and Turbulence in the Middle Atmosphere and
Lower Ionosphere, and

 

COSPAR-26-C2.2: Layered Phenomena in the Middle Atmosphere.

 

C2.1: Gravity Waves and Turbulence in the Middle Atmosphere and Lower
Ionosphere Gravity waves and turbulence are central to our understanding of
the neutral middle atmosphere and ionosphere, yet key questions remain
regarding wave generation and propagation, instabilities and wave breaking,
secondary wave generation, energy transfer to turbulence, and coupling
between atmospheric layers. This session aims to bring together experts
working on these topics in the middle atmosphere and lower ionosphere. We
welcome theoretical, modelling, experimental, and observational studies
related to gravity waves or turbulence in this region.

 

C2.2: Layered Phenomena in the Middle Atmosphere Physical and chemical
processes in the Mesosphere and Lower Thermosphere (MLT) give rise to a rich
variety of layered structures. These include metal layers formed by meteoric
input and space debris, ice-related features such as noctilucent clouds
(NLC), radar phenomena such as Polar Mesosphere Summer Echoes (PMSE) and
Winter Echoes (PMWE), and dynamically driven structures such as mesospheric
inversion layers and turbulent layers. These layers act as tracers of
atmospheric dynamics and vertical coupling on timescales from seconds to
decades. Recently, metal layers have gained additional relevance as
indicators of anthropogenic pollution from reentering space debris. This
session invites contributions on topics including middle atmosphere
dynamics, long-term trends, solar-cycle effects, vertical coupling
processes, and the impact of human activity on MLT composition.

 

We encourage submissions that exploit synergies between different
instruments, platforms, and models, and that highlight links between
dynamics, chemistry, and space-weather-related impacts.

 

Please submit your abstract via the COSPAR online system, selecting
Commission C, Sub-Commission C2, and the appropriate session (C2.1 or C2.2).

Feel free to forward this invitation to colleagues who may also be
interested.

 

We look forward to receiving your contribution and to an engaging set of
discussions at COSPAR-26.

 

With best regards,

 

Robin Wing, Boris Strelnikov, Michael Gerding, & Corwin Wright

COSPAR-26-C2.1 and COSPAR-26-C2.2
