About the research project
The project will seek to better understand aerosol-cloud interaction in pristine clouds at Kennaook/Cape Grim using both field campaign data and a regional atmospheric model
Kennaook/Cape Grim, located on the northwest coast of Tasmania, is considered as an excellent location to observe 'baseline' air, i.e. pristine Southern Ocean airmasses (Gras & Keywood, 2017). Such pristine airmasses provide an excellent opportunity to understand atmospheric processes away from the influence of human activity, which can help us understand how our weather and climate is changing.
Climate and weather models still produce large significant Southern Ocean radiation biases that have been attributed to the poor simulation of aerosol-cloud processes in such pristine environments (Fiddes et al., 2022; Mallet et al., 2023). One of the primary reasons for this problem is the limited availability of observations in the area, leading to a lack of understanding of crucial cloud formation processes specific to the Southern Ocean (McFarquhar et al., 2020).
Beginning in April 2024, the Cloud and Precipitation Experiment at Kennaook (Cape-K) campaign will begin, through to September 2025 (Mace et al., 2023). This campaign will be complemented by a comparison voyage of the RV Investigator and a potential flight campaign. These extensive and co-ordinated field campaigns, targeting aerosol-cloud interaction, provide a rare opportunity for processes understanding, model evaluation and development across a range of seasons.
1.What are the microphysical and aerosol properties of different cloud types in pristine Southern Ocean airmasses?
2.Can a high-resolution model represent these microphysical and aerosol properties?
3.Can we improve the representation of these cloud properties by improving the aerosol and cloud microphysics in the model, or with machine learning?
4.What is the seasonal dependence of cloud properties with respect to aerosol sources and can we replicate this in an atmospheric model?
