The Total Column Carbon Observing Network in the Southern Hemisphere: constraining our understanding of the carbon cycle and climate. The global carbon cycle and the distribution, sources and sinks of greenhouse gases such as carbon dioxide and methane are crucial drivers of climate change. The Total Carbon Column Observing Network (TCCON) measures the amounts of greenhouse and other trace gases in the atmosphere by solar remote sensing from the ground with unprecedented accuracy and precision. ....The Total Column Carbon Observing Network in the Southern Hemisphere: constraining our understanding of the carbon cycle and climate. The global carbon cycle and the distribution, sources and sinks of greenhouse gases such as carbon dioxide and methane are crucial drivers of climate change. The Total Carbon Column Observing Network (TCCON) measures the amounts of greenhouse and other trace gases in the atmosphere by solar remote sensing from the ground with unprecedented accuracy and precision. TCCON data are the "gold standard" for total column measurements and an essential part of greenhouse gas science. They are used to improve knowledge of the carbon cycle and future climate change, both directly and by validating global-scale satellite measurements. This project will continue to expand TCCON in the southern hemisphere and the enhanced scientific understanding it will provide.Read moreRead less
The Contribution of Tropical Cyclones to the Earth Energy Budget. This project aims to quantify the tropical cyclone contribution to the earth energy budget to understand whether tropical cyclones feed back to the climate system. While existing literature focuses exclusively on the effects of climate change on tropical cyclone variability, this project switches this viewpoint around. One possible outcome is a better understanding of long-term tropical cyclone variability. This is particularly im ....The Contribution of Tropical Cyclones to the Earth Energy Budget. This project aims to quantify the tropical cyclone contribution to the earth energy budget to understand whether tropical cyclones feed back to the climate system. While existing literature focuses exclusively on the effects of climate change on tropical cyclone variability, this project switches this viewpoint around. One possible outcome is a better understanding of long-term tropical cyclone variability. This is particularly important for tropical cyclone vulnerable regions including the Australian east coast and the oil and gas industry off the Northwest Shelf. Furthermore, the anticipated knowledge gained by this project will inform international understanding on the impacts of tropical cyclones to the overall climate system.Read moreRead less
Breathe Well: Improving Cancer Imaging And Targeted Radiotherapy Using Audiovisual Biofeedback
Funder

Summary
Irregular breathing causes anatomical errors in medical images and consequently cancer targeting accuracy, resulting in poorer clinical outcomes and increased health care costs. We have developed and patented the Breathe Well Audio Visual (AV) biofeedback device, to improve breathing regularity. Our goal is to gather critical scientific information and reach commercial proof-of-concept objectives that will allow us to attract investment to establish a viable medical device enterprise.
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. This proposal improves that understanding through ....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. 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

This project aims to improve the understanding of the causes of variability in atmospheric greenhouse gases, leading to better knowledge of how such processes will evolve in a changing climate. The project expects to use new measurement techniques to gain information about the spatial and temporal variability of atmospheric greenhouse gases. With the use of regional and global scale models, the measurements will be used to understand greenhouse gas fluxes and provide independent verification of current estimates. Expected outcomes include improved methods for verifying greenhouse gas emissions, which will contribute to improved emissions inventories and accounting promised under international agreements.Read moreRead less
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
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.

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

Summary
The cause of the poleward shift of Earth's storm tracks and jet streams. Why do global climate models shift the atmospheric storm tracks and jet streams poleward in simulations of future climate? This project will determine the underlying causes of the most important circulation change that is projected to occur with increasing greenhouse gases, and will allow much more accurate regional climate projections.
