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.

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
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.

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
