Plasma layers, waves and fountains: Probing the ionosphere with over-the-horizon radars. The ionised layers of the Earth’s upper atmosphere – the ionosphere - bend radio waves emitted by HF radio communication and radar surveillance systems allowing detection of targets beyond the horizon. This research will provide direct scientific support to this infrastructure including the $1.8B Australian coastal surveillance radars used to locate and track ships and planes in our region and radio communic ....Plasma layers, waves and fountains: Probing the ionosphere with over-the-horizon radars. The ionised layers of the Earth’s upper atmosphere – the ionosphere - bend radio waves emitted by HF radio communication and radar surveillance systems allowing detection of targets beyond the horizon. This research will provide direct scientific support to this infrastructure including the $1.8B Australian coastal surveillance radars used to locate and track ships and planes in our region and radio communication links used by military personnel and civilians living or travelling in Australia’s remote territories. This project will also provide training in areas highly relevant to our partners in government and defense, potentially improve efficiency of scientific and military radars, and thus contribute to improving national security.Read moreRead less
Next generation space weather forecasts. Next generation space weather forecasts. This project aims to improve Australia's space weather prediction capabilities by developing space weather forecasts that use ground- and space-based GPS data. The Earth's ionosphere is temporally and spatially variable and the small number of observations limits understanding of its dynamics and effects on radio waves. Using ground- and space-based GPS to remotely sound the ionosphere increases this coverage and c ....Next generation space weather forecasts. Next generation space weather forecasts. This project aims to improve Australia's space weather prediction capabilities by developing space weather forecasts that use ground- and space-based GPS data. The Earth's ionosphere is temporally and spatially variable and the small number of observations limits understanding of its dynamics and effects on radio waves. Using ground- and space-based GPS to remotely sound the ionosphere increases this coverage and can be used to develop space weather forecasts tailored to industries that heavily rely on GPS and satellite communications. An expected direct outcome of this research is modernised space weather forecasts, with economic benefits for several industries.Read moreRead less
Prediction of solar activity and space weather by automated analyses of solar radio and magnetic field observations and simulations. This project will build world-recognised capabilities to forecast space weather events at Earth in time to take protective measures. It involves around the clock automated identification and analysis of specific solar radio bursts, forecasting solar activity that results in transients moving Earth-ward, and simulations to predict when these will reach Earth.
Space weather prediction via automated data analysis systems. The project will build world-recognised capabilities in forecasting space weather events at Earth, in time to take protective measures, identifying and analysing solar drivers of space weather, and modelling interplanetary space. Australia's scientific standing, expertise, and infrastructure will be strengthened in space science, complex systems, and multiple fields of physics.

Australia's scientific standing, expertise, and infrastructure will be strengthened in space science, complex systems, and multiple fields of physics. Better predictions will increase the utility of Ionospheric Prediction Service services to customers in government, industry, and society, leading to better communications, more assured access to space services, and reduced risks of damage to critical infrastructure. The project will enhance Australia's human capital and its role in global space efforts.Read moreRead less
Geomagnetic induced currents in the Australian electricity supply network. This project will develop measures to protect the Australian electricity supply network from adverse effects of enhanced solar activity. This is essential for risk assessment and long term asset management of the Australian electricity network.

Wave energy transport, conversion and dissipation in near-Earth space. The near-Earth space environment is characterised by cycles of energy transport, conversion and release through particle acceleration that lead to dazzling aurora and damaged spacecraft and communication systems. This research seeks to identify how this energy is transported through space and the means through which it is converted and released.

COUPLING OF SOLAR WIND ENERGY INTO THE EARTH'S ENVIRONMENT. We will investigate energy transfer from the solar wind to the Earth's space environment, and down to low altitudes. The coupling occurs via reconnection between geomagnetic and interplanetary field lines, ultra-low frequency waves, and momentum transfer. Signatures of these processes include perturbations in the ionosphere and the geomagnetic field and these will be examined using ionospheric radars and sounders (in Tasmania, Antarcti ....COUPLING OF SOLAR WIND ENERGY INTO THE EARTH'S ENVIRONMENT. We will investigate energy transfer from the solar wind to the Earth's space environment, and down to low altitudes. The coupling occurs via reconnection between geomagnetic and interplanetary field lines, ultra-low frequency waves, and momentum transfer. Signatures of these processes include perturbations in the ionosphere and the geomagnetic field and these will be examined using ionospheric radars and sounders (in Tasmania, Antarctica, Canada and Alaska) and magnetometers (Antarctica and Alaska). Space weather can profoundly affect satellite, radio and terrestrial communication networks and observations of the type described here are essential to the development of realistic space weather models.Read moreRead less

Completion of the Tasman International Geospace Environment Radar (TIGER). TIGER is part of an international high frequency radar consortium (SuperDARN) studying the coupling of space weather processes to the ionosphere. This is critical for radio, navigation and surveillance networks.

TIGER is part of an international high frequency radar consortium (SuperDARN) studying the coupling of space weather processes to the ionosphere. This is critical for radio, navigation and surveillance networks. TIGER provides important new information because it extends the global radar coverage significantly equatorward, and it can be combined with other radars in Antarctica and Alaska. However, only one of the two TIGER radars necessary to carry out these studies has been built. This proposal is for completion of the second radar, to be located in New Zealand. The US Air Force has already granted A$443k toward this project.Read moreRead less
