Physical, Chemical and Radiative Characteristics of Australian Continental Aerosols. Australian desert dust, and the biomass burning aerosol particles produced in the top-end burning season, have the potential to impose an environmental burden not only on Australia, but also on the surrounding region. While most of the world's major aerosol types have been well studied in recent years, these two remain largely unknown. There are good reasons to believe that Australian aerosols are different from ....Physical, Chemical and Radiative Characteristics of Australian Continental Aerosols. Australian desert dust, and the biomass burning aerosol particles produced in the top-end burning season, have the potential to impose an environmental burden not only on Australia, but also on the surrounding region. While most of the world's major aerosol types have been well studied in recent years, these two remain largely unknown. There are good reasons to believe that Australian aerosols are different from many others. We therefore intend to fully characterize their relevant properties, so we may monitor them from space, and evaluate their environmental impacts.Read moreRead less

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
Better greenhouse gas budgets: new techniques and applications. The most recent (2001) international assessment strongly confirms the link between global climate change and human-induced changes in atmospheric composition. However, improved knowledge of atmospheric trace gas budgets is essential for better modelling of future climate change and formulation of public policy. We have developed novel techniques for atmospheric trace gas and isoptic analysis that provide new tools for resolving trac ....Better greenhouse gas budgets: new techniques and applications. The most recent (2001) international assessment strongly confirms the link between global climate change and human-induced changes in atmospheric composition. However, improved knowledge of atmospheric trace gas budgets is essential for better modelling of future climate change and formulation of public policy. We have developed novel techniques for atmospheric trace gas and isoptic analysis that provide new tools for resolving trace gas budgets in ways not previously possible. We will apply these tools to improve our understanding of the Australian and global budgets of greenhouse gases, especially nitrous oxide and methane, for which sources still have unacceptably large uncertainties.Read moreRead less
Chemistry of the Archaean Ocean and its Impact on Earth's Early Atmosphere and Ecosystems. The Pilbara Craton (WA) contains some of the oldest and best preserved Archaean rocks and microfossils in the world. These rocks, which were recently drilled as part of a collaborative effort between France and Australia, present an unprecedented opportunity to study the composition of the Earth's early atmosphere, ocean and life.

These rocks, which were recently drilled as part of a collaborative effort between France and Australia, present an unprecedented opportunity to study the composition of the Earth's early atmosphere, ocean and life. The research will strengthen Australia's strategic links with international experts and will provide access to the state-of-the-art synchrotron facility in France. The project links fundamental processes that shaped the Earth and thus fits into National Research Priority 1: An Environmentally Sustainable Australia.Read moreRead less
Innovative measurement and modelling of greenhouse fluxes at regional scales across Australia. Carbon dioxide accounts for around 60% of the enhanced greenhouse effect. This proposal aims to markedly improve knowledge of the exchange of carbon, mostly as CO2, between atmospheric, ocean and land-based reservoirs in the Australian region. This will be achieved through a suite of measurements using innovative technologies: satellite and ground based remote sensing as well in situ measurements at ....Innovative measurement and modelling of greenhouse fluxes at regional scales across Australia. Carbon dioxide accounts for around 60% of the enhanced greenhouse effect. This proposal aims to markedly improve knowledge of the exchange of carbon, mostly as CO2, between atmospheric, ocean and land-based reservoirs in the Australian region. This will be achieved through a suite of measurements using innovative technologies: satellite and ground based remote sensing as well in situ measurements at Darwin and on the Ghan railway from Darwin to Adelaide. The measurements will be used to constrain inverse models of the carbon cycle and significantly reduce uncertainties in regional carbon source estimates. These estimates will in turn be compared to the Australian National Greenhouse Gas Inventory for comparison and verification.Read moreRead less
Atmospheric composition and climate change. Changing composition and distribution of atmospheric trace gases and aerosols are the driving forces behind changes in climate and the environment at the earth's surface. This proposal is to undertake a program of ground based infrared remote sensing measurements as part of the Network for Detection of Stratospheric Change to investigate some of the most relevant atmospheric processes and species central to the greenhouse effect and ozone depletion.

This proposal is to undertake a program of ground based infrared remote sensing measurements as part of the Network for Detection of Stratospheric Change to investigate some of the most relevant atmospheric processes and species central to the greenhouse effect and ozone depletion. State-of-the-art measurements, advances in analysis techniques, and the measurement of isotopic fractionation will all contribute to advances in capabilities. Validation of satellite-based remote sensing instruments is also an important facet of the work.Read moreRead less
The carbon cycle and climate: new approaches to atmospheric measurements and modelling. Earth's climate is intimately connected to the carbon cycle, which controls atmospheric CO2 through processes such as photosynthesis, respiration and ocean uptake. A thorough understanding of the carbon cycle, and potential feedbacks with climate change, is prerequisite knowledge for informed assessments of future climate, impacts, adaptation and mitigation.

Earth's climate is intimately connected to the carbon cycle, which controls atmospheric CO2 through processes such as photosynthesis, respiration and ocean uptake. A thorough understanding of the carbon cycle, and potential feedbacks with climate change, is prerequisite knowledge for informed assessments of future climate, impacts, adaptation and mitigation. This proposal improves that understanding through measurements of CO2 and other key Kyoto-protocol greenhouse gases, links to global networks and satellite measurements, and advanced modelling. Australian science has a very important role to play in international networks due to our unique combination of southern hemisphere location and scientific standing. Read moreRead less
