Polar Cap Region Boundary Dynamics. Geomagnetic storms have the potential to severely impair critical technology infrastructure. Consequences of strong geomagnetic activity can include power failures, pipeline corrosion, satellite failures, inaccurate GPS positioning and radio navigation. Knowledge of how, where and under which conditions this activity occurs is therefore crucial. The primary aim of this project is to extend our knowledge of the mechanisms by which this activity occurs. This wor ....Polar Cap Region Boundary Dynamics.

Knowledge of how, where and under which conditions this activity occurs is therefore crucial. The primary aim of this project is to extend our knowledge of the mechanisms by which this activity occurs. This work will consolidate Australia's international space profile and provide excellent training in this field, helping Australia's future technology development.Read moreRead less
Ground based monitoring of plasma dynamics in the magnetosphere. We will use a new technique to study the plasmapause, a fundamental and highly dynamic boundary in geospace. This is usually examined using spacecraft and ground-based VLF measurements, but these suffer several limitations. We have developed the ability to monitor plasma density in geospace, by measuring the resonant frequency of geomagnetic field line oscillations.

We will use a new technique to study the plasmapause, a fundamental and highly dynamic boundary in geospace. This is usually examined using spacecraft and ground-based VLF measurements, but these suffer several limitations. We have developed the ability to monitor plasma density in geospace, by measuring the resonant frequency of geomagnetic field line oscillations. This project will use data from extensive ground magnetometer arrays to thus study the spatial and temporal variation in particle density near the plasmapause. Comparison with VLF and spacecraft measurements will provide new information on the plasma composition and dynamics in this important region.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
