Southern Ocean aerosols: sources, sinks and impact on cloud properties. This project aims to provide fundamental process-level understanding of atmospheric aerosol processes over the Southern Ocean, a region that has a profound influence on the Australian and global climate and where climate models perform poorly. Comprehensive observations during 3 Southern Ocean voyages and land-based measurements will enhance our knowledge of aerosols and cloud formation in that region and provide much-needed ....Southern Ocean aerosols: sources, sinks and impact on cloud properties. This project aims to provide fundamental process-level understanding of atmospheric aerosol processes over the Southern Ocean, a region that has a profound influence on the Australian and global climate and where climate models perform poorly. Comprehensive observations during 3 Southern Ocean voyages and land-based measurements will enhance our knowledge of aerosols and cloud formation in that region and provide much-needed data for improving global climate models. Expected outcomes include more accurate seasonal and latitudinal representations of Southern Ocean aerosol populations, properties and sources. The main benefit includes improvements in weather forecasting and future climate projection for Australia and the Southern Hemisphere.Read moreRead less

Summary
Microbial life in the atmosphere. This project aims to resolve the nature and basis of microbial life in the atmosphere, the largest but most unexplored potential ecosystem on Earth. The atmosphere plays a role in transporting microbes, but our understanding of resident atmospheric microbial communities and their role in global atmospheric processes is minimal. Using cutting-edge molecular and biogeochemical approaches, this project aims to identify true microbial residents of the atmosphere, un ....Microbial life in the atmosphere. This project aims to resolve the nature and basis of microbial life in the atmosphere, the largest but most unexplored potential ecosystem on Earth. The atmosphere plays a role in transporting microbes, but our understanding of resident atmospheric microbial communities and their role in global atmospheric processes is minimal. Using cutting-edge molecular and biogeochemical approaches, this project aims to identify true microbial residents of the atmosphere, understand their mechanisms for survival in this environment and explore their role in seeding newly formed environments. The anticipated outcomes include fundamental knowledge on atmospheric microbial ecosystems, and their influence on global atmospheric processes.Read moreRead less
Making Australia resilient to airborne infection transmission. The COVID-19 pandemic demonstrated that basic questions regarding how to minimise the risk of airborne infection transmission for any respiratory viruses remain unanswered, despite their frequency and huge social and economic costs. Therefore, this project aims to expand scientific knowledge and develop practical tools to improve the resilience of Australian indoor environments against airborne transmission of respiratory viruses. T ....Making Australia resilient to airborne infection transmission. The COVID-19 pandemic demonstrated that basic questions regarding how to minimise the risk of airborne infection transmission for any respiratory viruses remain unanswered, despite their frequency and huge social and economic costs. Therefore, this project aims to expand scientific knowledge and develop practical tools to improve the resilience of Australian indoor environments against airborne transmission of respiratory viruses. The outcomes of the project conducted by a multidisciplinary international team of collaborators will include: (i) quantitative knowledge on virus-laden aerosols from human expiration; and (ii) exposure and infection risk models and their application to typical indoor building and transport scenarios.Read moreRead less
