CAWCR technical report, 49. Techniques involved in developing the Australian Climate Observations Reference Network - Surface Air Temperature (ACORN-SAT) dataset
The Australian Climate Observations Reference Network – Surface Air Temperature (ACORNSAT) data set is a long-term data set of Australian daily air temperature, covering the period from 1910 to the present. The purpose of this data set is to provide the best possible data set to underlie analyses of variability and change of temperature in Australia, including both analyses of annual and seasonal mean temperatures, and of extremes of temperature and other information derived from daily temperatures. A full discussion of the motivation underlying the ACORN-SAT data set is contained in a compani ...
Recovery from disaster: resilience, adaptability and perceptions of climate change
NCCARF, 2012Focused on four disaster-impacted communities in Australia - Beechworth, Bendigo, Ingham and Innisfail, this report makes recommendations for emergency management and local government policies. It presents a study that used Bronfenbrenner’s bioecological systems theory to analyse individual and, by proxy, community resilience to disasters. The theory provided a comprehensive framework to evaluate the interacting factors that support resilience across different disaster sites and communities. While Bronfenbrenner’s theory has been used extensively, the authors believe that this is the first tim ...

Flood risk, insurance and emergency management in Australia
This paper is based on research being conducted with assistance from the Bushfire CRC on the role of insurance in responding to natural hazards. It identify some causes of underinsurance, with particular reference to floods, and consider steps that individuals, insurers and governments may take to both increase the uptake of insurance whilst also increasing community resilience. This paper reviews the lessons from the Queensland floods (December 2010 – February 2011) and identifies that two major issues are the cost and availability of flood cover. It is argued that if insurers assist with mit ...

CAWCR technical report, 43. Exploring the co-benefit of electric vehicle uptake and ozone pollution reduction in Sydney - Final report.
Given the likely pace of change in the electric vehicle market, it is important that the environmental externalities are identified and quantified. In this report we present the results of a modelling study which investigated how ozone pollution in the Greater Metropolitan Region of Sydney NSW, Australia would respond to the replacement of Sydney’s internal combustion engine (ICE) passenger vehicle fleet with a fleet of electric vehicles. A brief description of the modelling methodology is provided in the next section, and a summary of the modelling outcomes is provided in the following sectio ...
CAWCR technical report, 45. Evaluation of the TIGER SuperDARN Over-The-Horizon radar systems for providing remotely sensed marine and oceanographic data over the Southern Ocean
Greenwood Robert; Schuiz Eric; Parkinson Murray; et al. - Centre for Australian Weather and Climate Research, 2011The Tasman International Geospace Environment Radar systems (TIGER) located in Tasmania and New Zealand are High Frequency (HF) Over-The-Horizon Radar (OTHR) systems and represent Australia’s contribution to the Super Dual Auroral Radar Network (SuperDARN). SuperDARN is a network of more than 20 HF radars located at mid-high latitudes with fields of view covering the polar regions for the study of ionospheric physics. The TIGER systems have overlapping fields of view that cover much of the Southern Ocean in the Australian sector. The development and operation of TIGER has been led by La Trobe ...
CAWCR technical report, 44. Composition of the atmosphere - abstracts of the fifth CAWCR Workshop 15 November - 17 November 2011, Melbourne, Australia
The aims of the meeting are to: 1) understand the role of atmospheric chemistry and composition in global atmospheric change as expressed in the Australasian region and internationally; and 2) to provide a forum for atmospheric composition researchers from different disciplines (in-situ observations, remote sensing observations, modelling) to share ideas, enhance collaboration and develop a coordinated regional approach to characterising atmospheric processes in Australasia.
CAWCR technical report, 42. Global climate goals for temperature, concentrations, emissions and cumulative emissions
Raupach Mickael R.; Harman Ian N.; Canadell Josep G. - Centre for Australian Weather and Climate Research, 2011There are many different ways of quantifying the broad goal of "avoidance of dangerous human interference with the climate system", including targets for global temperature rise, radiative forcing, greenhouse gas (GHG) concentrations, GHG emissions in particular years, and cumulative GHG emissions ("carbon budgets"). The purpose of this report is to provide relationships between these different statements of a climate goal. Broadly, the approach is to start from target for global temperature increase above preindustrial temperatures (such as two degrees Celsius or any other target, to be met w ...
CAWCR technical report, 40. Comparison of techniques for the calibration of coupled model forecasts of Murray Darling Basin seasonal mean rainfall
Charles Andrew; Hendon Harry H.; Wang Q.J.; et al. - Centre for Australian Weather and Climate Research, 2011Ensemble forecasts of South Eastern Australian rainfall from POAMA 1.5, a coupled oceanatmosphere dynamical model based seasonal prediction system run experimentally at the Bureau of Meteorology, tend to be under dispersed leading to overconfident probability forecasts. The poor reliability of seasonal forecasts based on dynamical coupled models is a barrier to their adoption as official outlooks by the Bureau of Meteorology. One approach to correcting this problem is model calibration, in which the probability distribution produced by the model is adjusted in light of available information ab ...
CAWCR technical report, 39. Assessment of international seasonal rainfall forecasts for Australia and the benefit of multi-model ensembles for improving reliability
In this report we assess forecasts from Predictive Ocean Atmosphere Model for Australia (POAMA) in comparison to international dynamical coupled model forecast systems, which are archived as part of the ENSEMBLES project. We investigate how universal the lack of reliability is in dynamical forecasts of regional rainfall, in order to highlight any potential for improvement of the POAMA system. The systems assessed in this report show that overconfidence and lack of reliability for regional rainfall forecasts is a common problem. Due to the clear need for improved reliability and more accurate s ...
CAWCR technical report, 37. Large-scale indicators of Australian East Coast lows and associated extreme weather events
Extra-tropical cyclones that develop near the east coast of Australia often have severe consequences such as flash flooding and damaging winds and seas, as well as beneficial consequences such as being responsible for heavy rainfall events that contribute significantly to total rainfall and runoff. There is subjective evidence that the development of most major events, commonly known as East Coast Lows, is associated with the movement of a high amplitude upper-tropospheric trough system over eastern Australia. This report examines a number of large-scale diagnostic quantities in the upper trop ...

Climate: observations, projections and impacts
The Met.Office, 2011Understanding the potential impacts of climate change is essential for informing both adaptation strategies and actions to avoid dangerous levels of climate change.
But assessing the impacts is scientifically challenging and has, until now, been fragmented. To date, only a limited amount of information about past climate change and its future impacts has been available at national level, while approaches to the science itself have varied between countries.
In April 2011, we were asked by the United Kingdom's Secretary of State for Energy and Climate Change to begi ...

CSIRO Climate Adaptation Flagship working paper series, 7. Current and potential applications of typologies in vulnerability assessments and adaptation science
Typologies are a systematic grouping of entities or units of interest based on similarity. Typologies are widely applied in a variety of domains of research and practice including natural resource management, agriculture, health, marketing and development. They are used mainly to reduce complexity in the domain of concern to improve understanding and communication, detect patterns, aid decisions, prioritise and allocate resources, and tailor a variety of activities, strategies and processes. In this paper, we assess the current use of typologies within the realm of climate vulnerability assess ...

Manual on estimation of Probable Maximum Precipitation (PMP)
The manual describes procedure for estimating the maximum probable precipitation and the maximum probable flood. This is the third revised version.
The first and second editions of this manual were published in 1973 and 1986, respectively. The current edition keeps a majority of the content from the second edition. Newly added content in this third edition primarily results from experiences, since 1986, in directly estimating PMP for the requirements of a given project in a design watershed on probable maximum flood (PMF) in China, the United States of America, Australia and India.
