This project aims to understand how peroxyl radical reactions modulate the composition of air. The gas-phase chemical reactions of organic peroxyl radicals contribute to air quality in clean and polluted environments. However, experimental observations of these reaction intermediates and the complex mechanisms governing their formation and fate are limited. This project will use mass spectrometry and laser-based methods to interrogate the chemical and photochemical reactions of peroxyl radicals in the gas phase. This project expects to understand the composition and dynamics of the troposphere and inform strategies to improve air quality.Read moreRead less
The dynamics of turbulent entrainment in sheared convective boundary layers. This project aims to develop general laws to enable the accurate prediction of boundary layer entrainment processes. This will be significant in a wide range of environmental and engineering applications. In particular, the current lack of understanding of this area is a major source of uncertainty in the latest generation of global climate models.
GBR as a significant source of climatically relevant aerosol particles. Every cloud drop is formed from a microscopic aerosol particle, known as a cloud condensation nuclei (CCN). In unpolluted environments the CCN particles originate from biogenic sources. Determining the magnitude and driving factors of biogenic aerosol production in different ecosystems is crucial to the development and improvement of climate models. This project aims to determine the mechanisms of new particle production fro ....GBR as a significant source of climatically relevant aerosol particles. Every cloud drop is formed from a microscopic aerosol particle, known as a cloud condensation nuclei (CCN). In unpolluted environments the CCN particles originate from biogenic sources. Determining the magnitude and driving factors of biogenic aerosol production in different ecosystems is crucial to the development and improvement of climate models. This project aims to determine the mechanisms of new particle production from one of the biggest ecosystems in Australia, the Great Barrier Reef. It is expected that the project will establish whether marine aerosol along the Queensland coast is coral-derived and show that this aerosol can affect the CCN concentration and therefore cloud formation and the hydrological cycle.Read moreRead less
