First announcement: Middle Atmosphere symposium at the IAMAS-IACS-IAPSO Joint Assembly BACO2025, Busan (Republic of Korea), 20-25 July 2025

The Middle Atmosphere Symposium covers all aspects of middle atmospheric science, with emphasis on the interaction between dynamics, radiation and chemistry within the middle atmosphere itself and between the middle atmosphere and the troposphere. Observational, modelling, theoretical, and laboratory studies are all solicited. Research topics include (but are not limited to): 

– Gravity waves, their generation, propagation and breaking Sub-seasonal to decadal dynamical variability in the Middle Atmosphere 

– Middle Atmosphere response to anthropogenic and natural forcings 

– Stratospheric/Mesospheric chemistry and ozone 

– Radiation, microphysics, chemistry and dynamics at the tropopause

– Transport and mixing in multiple spatial scales 

– Tropical / extratropical dynamical interactions

– Vertical coupling in the Middle Atmosphere 

– Mechanisms of Stratosphere-Troposphere coupling, at all time scales 

– Role of the Middle Atmosphere on surface climate predictions and projections.

Abstract submission opens on October 15th
