The Southern Ocean boundary layer: winds, turbulence, sea spray and clouds. Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO). This is a direct consequence of a poor understanding of the structure and dynamics of the SO atmospheric boundary layer, which has arisen from an inability to make the necessary observations in this harsh environment.

Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO). This is a direct consequence of a poor understanding of the structure and dynamics of the SO atmospheric boundary layer, which has arisen from an inability to make the necessary observations in this harsh environment. Due to the availability of new Australian research infrastructure, large steps forward are now possible with modest investment. This project will conduct and combine observations from the recently acquired marine vessel, RV Investigator, and the collocated airborne and surface observations to understand the structure and evolution of the unique, pristine SO boundary layer and to evaluate satellites and climate models.Read moreRead less

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

Global Influence of Intraseasonal Variability in Ozonesonde Profiles. This proposal aims to better understand how tropical intraseasonal variability (periods of 40 to 60 days) influences the chemical components of the global atmosphere. The results of the research aim to improve regional air-quality forecasts on weekly and monthly timescales. The highly vertically resolved ozone concentrations from the surface up to 20 kilometres, measured by balloon-borne instruments called ozonesondes, will be ....Global Influence of Intraseasonal Variability in Ozonesonde Profiles. This proposal aims to better understand how tropical intraseasonal variability (periods of 40 to 60 days) influences the chemical components of the global atmosphere. The results of the research aim to improve regional air-quality forecasts on weekly and monthly timescales. The highly vertically resolved ozone concentrations from the surface up to 20 kilometres, measured by balloon-borne instruments called ozonesondes, will be used as a dynamical tracer. The knowledge gained from the ozonesonde data will be used to elucidate the chemical origins of the tropical variability related to biomass burning activities and convective lightning, as well as the subtropical variability related to the polar vortex dynamics.Read moreRead less

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
The energetics and dynamics of chemical reactions of polyatomic molecules involving multiple electronic states. This project will produce, from first principles, the first quantitatively accurate computer simulations of chemical reactions which involve several atoms and multiple electronic states.

This project will produce, from first principles, the first quantitatively accurate computer simulations of chemical reactions which involve several atoms and multiple electronic states. Many of the most important chemical reactions in the atmosphere (and elsewhere) involve changing both the shape of the molecules and their electronic structure. Many of these reactions are difficult to study in the laboratory, and consequently computer simulation is an essential component of the study of such reactions. U nderstanding how these reactions occur, and how fast they proceed, are important to our understanding of the dynamics of the atmosphere and other large scale reactors.Read moreRead less
