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

Atmospheric integrated research on burdens and oxidative capacity. 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.

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
Tackling Atmospheric Chemistry Grand Challenges in the Southern Hemisphere. The project aims to provide a southern hemisphere perspective on current challenges in atmospheric chemistry: air quality, oxidation capacity, stratospheric change, and chemistry–climate interactions. Australia’s geographic position in the relatively clean southern hemisphere allows a unique opportunity to study environments with limited human influence, an opportunity that has largely been lost in the more populous nort ....Tackling Atmospheric Chemistry Grand Challenges in the Southern Hemisphere. The project aims to provide a southern hemisphere perspective on current challenges in atmospheric chemistry: air quality, oxidation capacity, stratospheric change, and chemistry–climate interactions. Australia’s geographic position in the relatively clean southern hemisphere allows a unique opportunity to study environments with limited human influence, an opportunity that has largely been lost in the more populous northern hemisphere. The intended outcomes of the project include validated ground-based and satellite datasets for monitoring Australia’s air quality, improved atmospheric models for predicting future atmospheric change, and a deeper understanding of the processes driving atmospheric composition worldwide.Read moreRead less

Planetary Nitrile Chemistry: Synchrotron Spectroscopic Investigations. Observed in planetary atmospheres such as Saturn's moon Titan, cyanide-based aerosols undergo photolytic processing to generate complex organic material of prebiotic interest. However, dedicated spectroscopic experiments directed at nitrile aerosol analogues have not been performed to date. To bridge this gap, a custom cooling cell at the Australian Synchrotron will be used to investigate condensed-phase nitriles at Titan con ....Planetary Nitrile Chemistry: Synchrotron Spectroscopic Investigations. Observed in planetary atmospheres such as Saturn's moon Titan, cyanide-based aerosols undergo photolytic processing to generate complex organic material of prebiotic interest. However, dedicated spectroscopic experiments directed at nitrile aerosol analogues have not been performed to date. To bridge this gap, a custom cooling cell at the Australian Synchrotron will be used to investigate condensed-phase nitriles at Titan conditions. Laser irradiation of nitrile ice particles will then follow; designed to simulate photochemical processes in the Titan atmosphere. The project aims to use data compiled for nitrile aerosols and their photolytic products to assist in assigning these species to unconfirmed bands within infrared surveys of planetary environments.Read moreRead less
