Established in 2018, the Southern Hemisphere working group was founded in order to:
- Provide a forum for scientists to discuss particular challenges in understanding the Southern Hemisphere atmosphere &
- To foster stronger collaborations between Southern Hemisphere research groups.
Current Activities:
PARTICIPATE in GEIA 2025 Conference

Increasingly, the chemistry and dynamics of the stratosphere and troposphere are being studied and modeled as a single entity in global models. As evidence, in support of the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5), several groups performed simulations in the Coupled Model Intercomparison Project Phase 5 (CMIP5) using global models with interactive chemistry spanning the surface through the stratosphere and above.
With the view that improving the understanding of atmospheric science in Africa would have large impacts on key societal issues for the continent (e.g. air quality, human health, agriculture, climate change), the African Group on Atmospheric Sciences (ANGA) working group has been established. ANGA, which means “atmosphere” in Kiswahili, proposes to focus on uniting atmospheric expertise across Africa and fostering the next generation of atmospheric scientists.
Wet and dry deposition of chemical species to the earth’s surface plays an essential role in controlling the concentration of gases and aerosols in the troposphere. The chemical composition of atmospheric deposition provides important information on many interacting physical and chemical mechanisms in the atmosphere such as emission sources, atmospheric dynamics and transport, atmospheric removal processes, and nutrient cycling in ecosystems.
