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.

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

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

Summary
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 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.

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

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 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

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
