Precise Atmospheric Density Correction Model Using Space Tracking Data for Accurate Debris Surveillance and Collision Warning. Our project will build new atmospheric density correction models (ADCMs) for accurate prediction of debris object and satellite orbits. This research will have tremendous impacts on realizing unaided debris laser ranging. An order of magnitude accuracy improvement to the ADCMs will lead to a significant breakthrough in space object tracking. The benefits of this research ....Precise Atmospheric Density Correction Model Using Space Tracking Data for Accurate Debris Surveillance and Collision Warning. Our project will build new atmospheric density correction models (ADCMs) for accurate prediction of debris object and satellite orbits. This research will have tremendous impacts on realizing unaided debris laser ranging. An order of magnitude accuracy improvement to the ADCMs will lead to a significant breakthrough in space object tracking. The benefits of this research are: it will put Australia in a leading position in the world on ADCM study; to maintain Australia's leading role in space surveillance and greatly enhanced operational capability & efficiency of Australian space tracking systems; and to contribute significantly to the space environment info management, e.g. accurate collision warning and space junk tracking.Read moreRead less
Improving Projections of Regional Climate Change for Australia Using Detection and Attribution Studies. The Intergovernmental Panel on Climate Change concluded in 2001 that "most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations" and that "anthropogenic climate change will persist for many centuries". This project will reduce uncertainties in projections of future climate change for Australia. We will compare model-simulate ....Improving Projections of Regional Climate Change for Australia Using Detection and Attribution Studies. The Intergovernmental Panel on Climate Change concluded in 2001 that "most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations" and that "anthropogenic climate change will persist for many centuries". This project will reduce uncertainties in projections of future climate change for Australia. We will compare model-simulated climate changes during the twentieth century with observed changes globally and in the Australian region. These comparisons will be used with statistical modelling to estimate probability distributions for future changes in Australian climate.Read moreRead less
