CEDAR email: AOGS2026 session AS25: Advanced Topics in the Whole Atmosphere: Remote and In-situ Sensing and Modelling of the Chemistry and Dynamics of the Middle and Upper Atmosphere

[Stefan Bender]

Dear Colleagues,

One week left, deadline 23 January 2026, at 23:55 (GMT+8).

We would like to invite you to submit an abstract to session AS25
at AOGS 2026, which takes place in Fukuoka, Japan, from 2--7 August 2026.
Together with session AS19, this session is part of two joint
sessions for "Advanced Topics in the Whole Atmosphere".

AOGS2026 session AS25:
Advanced Topics in the Whole Atmosphere: Remote and In-situ
Sensing and Modelling of the Chemistry and Dynamics of the
Middle and Upper Atmosphere

Session Description:
The Earth's middle and upper atmosphere and ionosphere maintain
a balance between solar radiative and particle forcing from
above, and the action of atmospheric waves rising up from below.
Quantifying how these forces drive the general circulation and
waves in the atmosphere and control both the chemical balance
and its temporal and spatial variability is crucial to
understanding how composition, momentum, and energy couple
together and structure the atmosphere and ionosphere. As a
result, remote sensing and in-situ investigations, as well as
the laboratory and modelling studies that complement and explain
these observations, are the primary tools used to understand the
aeronomy of this region. This session will look at recent
results from those ground-based, in-situ and satellite-borne
observations, modelling studies and relevant laboratory
research. It will bring together studies of new sensing
techniques and sensors, models and mission concepts, currently
being planned or under development, to foster new
collaborations, furthering the impact of their integrated
results on our understanding of the stratosphere, mesosphere and
ionosphere/thermosphere.

We look forward to your participation in this AOGS session.
Please note that the abstract submission deadline is Friday,
23 January 2026, at 23:55 (GMT+8, Singapore Standard Time).

Kind regards,
Your conveners, Stefan Bender, Iain Reid, Jeng-Hwa Yee, Jia Jia
