CEDAR email: EGU session announcement

[Petr Šácha]

Dear colleagues, 

We would like to draw your attention to a new session of the EGU General 
Assembly 2023.

 

AS1.32 
Structural changes in the middle and upper atmosphere 
Convener: Juan Antonio Añel 
Co-conveners: M. G. Mlynczak, Viktoria Sofieva, Petr Šácha, Laura de la 
Torre

Evidence of the impacts of climate change on the middle and upper atmosphere
is increasing, making clear the critical need for observational data to 
monitor and understand trends. For example, a contraction of the 
stratosphere has been quantified, but we still face significant limitations 
on the data available to assess it. Past efforts to study trends have 
focused mainly on the atmospheric levels separately (mesosphere, 
thermosphere, ionosphere), where cooling and contraction have also been 
observed. Monitoring these trends and their impacts on satellites and space 
debris needs a continued effort, providing better data and improved insight 
into the consequences that increased carbon dioxide has on the middle and 
upper atmosphere.

 

We encourage abstract submissions concerning long-term as well as short-term
changes to the structure of the atmosphere, its parts or localized 
circulation phenomena and underlying mechanisms. We especially welcome 
presentations about existing data, data gaps and measurements to monitor 
trends in the middle and upper atmosphere and the impacts, for example, 
changes of the drag on space objects. Also, studies evaluating and 
documenting underlying causes and modelling or projecting changes of these 
mechanisms are particularly welcomed.


Two important deadlines: Abstract submission deadline is 10 January 2023, 
13:00 CET.

Applications for financial support are possible by submitting your abstract 
by 1 December 2022, 13:00 CET.

Sincerely, 
Petr Šácha.
