Climate change is a major global concern, with the potential for major consequences in Australia. This proposal contributes directly to climate change research relevant to Australia through direct measurements of the atmosphere relevant to the understanding of phenomena such as increasing greenhouse gas concentrations and stratospheric ozone depletion. Australia's geographical position in the less populated southern hemisphere, and its advanced scientific infrastructure, mean that it has an especially important and valuable role to play in global atmospheric research. The proposed research participates in several international research programmes.Read moreRead less
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

A low-cost water vapour profiler for the lower troposphere. Water vapour plays an important role in weather forecasting, as well as being the most important greenhouse gas. Its distribution is not known in sufficient detail for many aspects of predicting weather and climate change. With the Bureau of Meteorology we will develop a low-cost laser ranging system to measure the profile of water vapour in the lower atmosphere. A low-cost instrument can be placed at a sufficient number of locations ....A low-cost water vapour profiler for the lower troposphere.

With the Bureau of Meteorology we will develop a low-cost laser ranging system to measure the profile of water vapour in the lower atmosphere. A low-cost instrument can be placed at a sufficient number of locations to significantly enhance weather forecasting and climate modelling. The instrument will be useful for detecting fog formation, measuring cloudbase heights and can be adapted for pollution detection and measurement.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

Assimilation of trace atmospheric constituents for climate (ATACC): Linking chemical weather and climate. Changes in atmospheric ozone and carbon dioxide affect many aspects of surface climate from changes in ultraviolet radiation (ozone) to long-term changes in temperature (carbon dioxide). Better mapping of these gases will help us understand, predict and manage these changes. For ozone, it will clarify the link between ozone and surface weather. For carbon dioxide, improved knowledge of the ....Assimilation of trace atmospheric constituents for climate (ATACC): Linking chemical weather and climate. Changes in atmospheric ozone and carbon dioxide affect many aspects of surface climate from changes in ultraviolet radiation (ozone) to long-term changes in temperature (carbon dioxide). Better mapping of these gases will help us understand, predict and manage these changes. For ozone, it will clarify the link between ozone and surface weather. For carbon dioxide, improved knowledge of the impact of tropical deforestation, land clearing and changes in the southern ocean on atmospheric CO2 will support sustainable development in Australia and our region. The project hence addresses the priority goal 'Responding to climate change and variability` under the National Research Priority 'An Environmentally Sustainable Australia`.

The outcome of this project will result in a more thorough understanding of the role of water in the atmosphere and in the Greenhouse effect, and will provide information leading to more accurate modelling of Global warming. The results will also lead to new insights into interstellar chemistry, the chemistry of cometary dust and the origins of life.
Tackling Atmospheric Chemistry Grand Challenges in the Southern Hemisphere. The project aims to provide a southern hemisphere perspective on current challenges in atmospheric chemistry: air quality, oxidation capacity, stratospheric change, and chemistry–climate interactions.

The project aims to provide a southern hemisphere perspective on current challenges in atmospheric chemistry: air quality, oxidation capacity, stratospheric change, and chemistry–climate interactions. Australia’s geographic position in the relatively clean southern hemisphere allows a unique opportunity to study environments with limited human influence, an opportunity that has largely been lost in the more populous northern hemisphere. The intended outcomes of the project include validated ground-based and satellite datasets for monitoring Australia’s air quality, improved atmospheric models for predicting future atmospheric change, and a deeper understanding of the processes driving atmospheric composition worldwide.Read moreRead less
