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
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.
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.

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

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
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
What is the impact of abrupt climate change on the global carbon cycle? In the past 50 000 years there were several episodes of abrupt climate change during which atmospheric carbon dioxide rose significantly. This project aims to determine the causes of past abrupt changes in atmospheric carbon dioxide. The project is significant because understanding changes in the global carbon cycle is essential to estimate future climate trajectories. Innovatively, it will highlight the relationship between ....What is the impact of abrupt climate change on the global carbon cycle? In the past 50 000 years there were several episodes of abrupt climate change during which atmospheric carbon dioxide rose significantly. This project aims to determine the causes of past abrupt changes in atmospheric carbon dioxide. The project is significant because understanding changes in the global carbon cycle is essential to estimate future climate trajectories. Innovatively, it will highlight the relationship between Southern Hemisphere water masses and the marine carbon cycle during abrupt climate change. The expected outcomes include a better understanding of the interplay between Southern Ocean processes and the carbon cycle.Read moreRead less
