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
The changing relationship between the South Asian and Australian Monsoon in a warming world. The success or failure of the Australian and South Asian Monsoons can mean the difference between prosperity and severe hardship in the affected regions. This project will help to understand the causes of the monsoon variability, both natural and human-induced, and what the future might have in store.

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

This project aims to expand Australia's capacity to do high-impact innovative climate, weather and oceanographic science. Science of this kind relies on massive data coupled to computationally highly intensive and complex analysis. Therefore, the project will purchase fast disk storage and install it at the National Computing Infrastructure. It is anticipated that the project will benefit the nation through better understanding of the climate system, including extremes; improvements in our capacity to make predictions; and through applications of the science to forecasting, the management of resources among other many other things.Read moreRead less

Our capacity to assess the threat of climate change is undermined by an unacceptable level of uncertainty in the understanding and modelling of regional climates. The Centre will undertake world-class research targeting identified weaknesses in the physical, chemical and biological components of the climate system. We will engage and nurture graduate students and postdoctoral follows through a program of graduate training and mentoring to permanently transform our understanding of climate systems science particularly for the Australian region. The key outcome will be a dramatic enhancement in national capacity to understand and project the scale of future regional climate change.Read moreRead less

What is extreme? Advancing insights into Australia’s variable rainfall. This project aims to address fundamental questions about the causes of Australia’s rainfall variability, providing crucial information about how changing climates affect the water cycle. Bringing together earth system data from ground-based and satellite observations, palaeoclimate reconstructions and climate model simulations, it plans to analyse the processes that cause change in Australia’s rainfall.

This project aims to address fundamental questions about the causes of Australia’s rainfall variability, providing crucial information about how changing climates affect the water cycle. Bringing together earth system data from ground-based and satellite observations, palaeoclimate reconstructions and climate model simulations, it plans to analyse the processes that cause change in Australia’s rainfall. The project aims to integrate these datasets using the novel analysis of water isotopes, an important diagnostic of the water cycle. This approach is expected to help evaluate how Australia’s rainfall responds to natural and anthropogenic drivers and identify the processes behind recently observed rainfall extremes.Read moreRead less
Remote forcing of Pacific Ocean variability and impacts on global climate. Variability in the Pacific Ocean has a profound impact on global climate. Recent unprecedented decadal variability in the Pacific has been linked to global temperature trends and extremes, yet little is known about what drives this variability or its impact on regional climate.

Variability in the Pacific Ocean has a profound impact on global climate. Recent unprecedented decadal variability in the Pacific has been linked to global temperature trends and extremes, yet little is known about what drives this variability or its impact on regional climate. This project will combine observations, advanced coupled climate models and ocean-atmosphere dynamical theory to quantify remote drivers of Pacific Ocean variability on interannual-decadal time-scales. This project aims to enhance our understanding of the modes of variability operating in this region and their impact on global and Australian climate. This will have significant benefits for the many sectors of society reliant on interseasonal-decadal climate prediction.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
El Niño in a changing climate: novel long-term perspectives from Pacific corals and model simulations. El Niño and La Niña events have a profound influence on Australian drought conditions and rainfall.

El Niño and La Niña events have a profound influence on Australian drought conditions and rainfall. Forecasting is hampered by short climate records, which do not capture the full range of El Niño dynamics. This project aims to generate records of unprecedented length and spatial coverage from key sites across the western and central equatorial Pacific. Five hundred years of continuous, monthly-resolution climate data will be integrated with output from state-of-the-art climate model simulations to distil the key processes that cause El Niño to vary. This project aims to provide major advances in determining the full range of El Niño and La Niña behaviour, leading to improved forecasts of future changes, with consequences for Australia's water security.Read moreRead less

Australia's agricultural productivity is strongly affected by climate, climate variability and climate change. Recent climate changes in Western Australia forced adaptation strategies costing $500 million while the anomalously intense 2002 Murray-Darling Basin drought significantly affected agriculture. Any further intensification of droughts would affect Australia's rural economy. This proposal will assess the role of terrestrial processes, linked to increasing CO2, in causing the drought intensification and declines in rainfall. This will provide knowledge that will guide the development of future environmental management strategies.Read moreRead less
