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
Understanding the Influence of Cloud on the Spectral Solar Ultraviolet Radiation. Terrestrial spectral solar UV may be enhanced above that of clear sky due to certain cloud conditions.

Terrestrial spectral solar UV may be enhanced above that of clear sky due to certain cloud conditions. There is a major gap in the scientific knowledge of the influence of cloud on the spectral solar UV and resultant biologically damaging UV. This project will collect the only dataset of sky conditions and spectral UV for each ten minute period spanning 12 months to determine: the specific wavelengths with increased irradiances; the amount of enhanced damaging UV; the cloud conditions that cause these enhancements and develop a predictive capability to determine when cloud cover will enhance solar UV.Read moreRead less

Greenhouse gas emission from sugarcane and mangrove communities in coastal Queensland. Greenhouse gases threaten the global climate. Many estimates of vegetation as sinks and sources for greenhouse gases have a high degree of uncertainty. This project will generate important information about greenhouse gas emissions from Queensland coastal vegetation. Characterised by moist and nutrient rich conditions, sugarcane fields and mangrove ecosystems represent significant sources/sinks of potent green ....Greenhouse gas emission from sugarcane and mangrove communities in coastal Queensland. Greenhouse gases threaten the global climate. Many estimates of vegetation as sinks and sources for greenhouse gases have a high degree of uncertainty. This project will generate important information about greenhouse gas emissions from Queensland coastal vegetation. Characterised by moist and nutrient rich conditions, sugarcane fields and mangrove ecosystems represent significant sources/sinks of potent greenhouse gases nitrous oxide and methane. Sugarcane and mangroves exposed to different nutrient inputs will allow to (i) identify mechanisms of N2O and CH4 emission, (ii) model N2O and CH4 emissions under different nutrient and climate conditions, and (iii) control/reduce emissions by improving coastal ecosystem management.Read moreRead less
Reactivity and photochemistry of halide anions: atmospheric implications. Bromine and iodine are suspected to be responsible for most of the halogen-induced ozone loss in the stratosphere but are not currently included in atmospheric models due to a paucity of knowledge of the gas-phase chemistry and photochemistry of their anions and radicals. This project will develop and deploy advanced mass spectrometry and laser spectroscopy techniques to enable precision measurements of the reactions and p ....Reactivity and photochemistry of halide anions: atmospheric implications. Bromine and iodine are suspected to be responsible for most of the halogen-induced ozone loss in the stratosphere but are not currently included in atmospheric models due to a paucity of knowledge of the gas-phase chemistry and photochemistry of their anions and radicals. This project will develop and deploy advanced mass spectrometry and laser spectroscopy techniques to enable precision measurements of the reactions and photo-reactions of gas-phase iodide and bromide anions and their oxides. These state-of-the-art measurements of reaction kinetics and products will enable accurate chemical models that predict the impact of bromine and iodine chemistry on ozone levels and will inform future models for global climate.Read moreRead less
QUANTIFICATION OF INTERACTIONS DURING THE DISPERSION OF CORONA IONS AND AIRBORNE PARTICLES NEAR POWER LINES. Currently there is no method for quantification of concentration and dispersion of charged aerosols near high voltage power lines (HVPLs). However, hypothesis have been presented, but not yet proven scientifically, that residents of houses close to combustion sources such as highways or industrial plants and HVPLs may be subjected to health risk due to inhalation of charged aerosols.

Currently there is no method for quantification of concentration and dispersion of charged aerosols near high voltage power lines (HVPLs). However, hypothesis have been presented, but not yet proven scientifically, that residents of houses close to combustion sources such as highways or industrial plants and HVPLs may be subjected to health risk due to inhalation of charged aerosols. The outcome of this project will be a model for quantitative assessment of the processes occurring during the transport and dispersion of corona ions and combustion aerosol, which will be a tool for predictive risk assessment and informed management of public resources in relation to power line design and maintenance.Read moreRead less

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
A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding .... A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise.
