Coherent LIDAR for Monitoring Air Pollution and Atmospheric Wind-fields. Industry, government and civil defence urgently require compact, field deployable sensors that can measure winds and monitor pollution in the atmospheric boundary layer. Without these sensors they are unable to measure and make informed decisions about windborne dispersion of industrial emissions, environmental pollutants, and chemical/biological toxins under operational conditions. The project will develop eye-safe cohere ....Coherent LIDAR for Monitoring Air Pollution and Atmospheric Wind-fields. Industry, government and civil defence urgently require compact, field deployable sensors that can measure winds and monitor pollution in the atmospheric boundary layer. Without these sensors they are unable to measure and make informed decisions about windborne dispersion of industrial emissions, environmental pollutants, and chemical/biological toxins under operational conditions. The project will develop eye-safe coherent lidar (light detection and ranging) systems that can measure wind velocities at ranges of up to 10 km with an accuracy of about 1 m/s, and can be deployed to field sites as required. The technology will be of major interest to the commercial sector.Read moreRead less
The aeronomy of the atmosphere between 50 and 110 km. Signals of climate change in the 50 to 110 km height region of the atmosphere are becoming more evident. This region shields the surface from extreme UV radiation and so understanding any changes in the region is important for life. We will improve our understanding of the region and look for additional evidence of changes. We will also contribute to improvements in numerical weather prediction models.
The Response of the Middle Atmosphere to Solar and Dynamical Forcing. The region of the atmosphere and ionosphere between 50 and 100 km is difficult to measure directly. We will use a unique array of instruments deployed across Australia to study how this region responds to waves generated in the lower atmosphere and to changes in electromagnetic energy from the sun and particle precipitation from the magnetosphere. Outcomes will help our understanding of how the region is responding to rising l ....The Response of the Middle Atmosphere to Solar and Dynamical Forcing. The region of the atmosphere and ionosphere between 50 and 100 km is difficult to measure directly. We will use a unique array of instruments deployed across Australia to study how this region responds to waves generated in the lower atmosphere and to changes in electromagnetic energy from the sun and particle precipitation from the magnetosphere. Outcomes will help our understanding of how the region is responding to rising levels of greenhouse gas concentrations. Cooling effects are already apparent and our research will look for additional evidence of change.Read moreRead less
Energetics, spectroscopy and dissociation dynamics of bimolecular complexes of atmospheric importance. The Global Warming debate illustrates the importance of having a firm scientific underpinning to calculations of the atmosphere. It is important in calculations of atmospheric chemistry to have all pathways and species properly accounted for. It has recently emerged that intermolecular complexes may play a role in atmospheric chemistry.

The Global Warming debate illustrates the importance of having a firm scientific underpinning to calculations of the atmosphere. It is important in calculations of atmospheric chemistry to have all pathways and species properly accounted for. It has recently emerged that intermolecular complexes may play a role in atmospheric chemistry. Of these, those involving water are very important because of water's ability to form strong hydrogen bonds. This project will provide key experimental data on one of the most important complexes, the water-hydroxyl radical complex.Read moreRead less

Summary
A New Digital Radar for Studies in Solar-Terrestrial and Atmospheric Physics. Australia is a world leader in the development of High Frequency (HF) radar surveillance systems, such as JORN (Jindalee over-the-horizon radar). However, Australia's ability to support these operations and remain a leader in these fields depends on its capacity to nurture expertise and train new personnel in these areas. The new HF radar system will play a crucial role in this respect, providing (i) high-level trainin ....A New Digital Radar for Studies in Solar-Terrestrial and Atmospheric Physics. Australia is a world leader in the development of High Frequency (HF) radar surveillance systems, such as JORN (Jindalee over-the-horizon radar). However, Australia's ability to support these operations and remain a leader in these fields depends on its capacity to nurture expertise and train new personnel in these areas. The new HF radar system will play a crucial role in this respect, providing (i) high-level training in radar technology and associated science, (ii) a test bed for the development of new instrumental and data analysis techniques, (c) new information on the source of ionospheric perturbations that can affect the performance of JORN, and (d) data important for Australia's space weather prediction community, via IPS (Ionospheric Prediction Service) Radio and Space Services.Read moreRead less
