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 global carbon cycle and the greenhouse gases carbon dioxide and methane are important drivers of climate change. Understanding the fluxes of these gases to and from the atmosphere is crucial for understanding past, present and future climate variability. This project focuses on using simultaneous co-located measurements of greenhouse gas amounts, together with modelling their atmospheric co-variability, to better estimate these fluxes by individual processes and on better temporal and spatial scales. In particular, co-located solar remote-sensing and in situ measurements will be combined, and the ability of the remote-sensing and in situ instruments to measure numerous gases will be exploited to improve flux estimates and atmospheric modelling.Read moreRead less
Atmospheric composition and climate change: a southern hemisphere perspective. This project addresses the science of greenhouse gases and climate change through extensive high accuracy measurements of atmospheric composition, the calibration of a new generation of satellite sensors, and the assimilation of the measured data in models of the atmosphere to elucidate the sources and sinks of greenhouse gases.

Atmospheric integrated research on burdens and oxidative capacity: No single player in the Australian research community can make a large suite of atmospheric composition measurements, while the combined capability of the community is tremendous. Providing a platform to bring this capability together is cost effective and is expected to provide strong scientific return. This defines the requirements for Atmospheric Integrated Research on Burdens and Oxidative capacity (AIR-BOX) to make a valuable contribution to Australian Atmospheric Science research. This project aims to provide a suite of mobile equipment including a chemical ionisation mass spectrometer, an ultraviolet-visible radiation spectrometer, a mini micropulse lidar, an in situ Fourier transform infrared spectrometer, and a cloud condensation nuclei counter. It will be capable of remote and autonomous deployment, real-time data transfer and control, a wide range of tracer measurements, flexible configuration, and physical as well as tracer measurements.Read moreRead less
Tropospheric ozone and air quality in Australia. Ozone is an important greenhouse gas and an air pollutant that causes adverse health effects. This research will increase our understanding of changing ozone concentrations. In addition it will improve our ability to forecast episodes of poor air quality within Australia, thereby reducing the health impacts of atmospheric pollution events.

Summary
Ultra-trace analytical facility for earth system change . A new cutting-edge research capability will be established to safe guard Australia's natural resources and environment and to determine past variability in climate. Research results from the facility will help to guide national and international policy makers with regards to sustainable development and management of resources.
Transformation of organics in the unpolluted atmosphere. This project will develop the chemistry needed to model the removal of methane and other organic compounds from the unpolluted atmosphere. While the chemistry of urban environments is now understood, there are major shortcomings when describing remote environments, limiting our ability to model the lifetimes of key greenhouse gases and toxins.

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.
The dynamics of subtropical anticyclones and the connection to drought, heatwaves and bushfires in southern Australia. The aim of the project is to understand the dynamics of anticyclones (high pressure systems) in the region of southern Australia. The study of anticyclones in the region is important because of their very strong connection to rainfall in the winter, and heatwaves and bushfires in the summer, and because so little work has been done on understanding what is the defining feature o ....The dynamics of subtropical anticyclones and the connection to drought, heatwaves and bushfires in southern Australia. The aim of the project is to understand the dynamics of anticyclones (high pressure systems) in the region of southern Australia. The study of anticyclones in the region is important because of their very strong connection to rainfall in the winter, and heatwaves and bushfires in the summer, and because so little work has been done on understanding what is the defining feature of the climate of southern Australia. Understanding what controls the location and strength of these features will go a long way to explaining how the climate of southern Australia will change in a warmer world.Read moreRead less

This project aims to determine how the frequency of intense tropical and subtropical thunderstorms will change as a result of future global warming. Climate models project that the energy available to such storms will increase in the future, but the reasons for this increase in available energy, and the implications for thunderstorm activity, remain uncertain. Using observations and high-resolution models, the project expects to generate new knowledge of the mechanisms driving changes in intense thunderstorm activity under climate change, and to provide more accurate projections of the frequency of intense thunderstorms in a warmer climate. This project should deliver benefits to sectors of the economy such as agriculture and transportation, which are significantly exposed to such hazards.Read moreRead less
