Gaseous emissions during bushfires are a significant component of the smoke generated. Understanding the controls on the composition of gases in smoke generated by the burning of vegetation is crucial to being able to predict the effect smoke has on atmospheric chemistry and the consequences this may have on the global C budget and human and plant health. Our current understanding of how trace gas emissions such as CO2, CO, and volatile organic compounds are affected by fuel condition is restricted to simple empirical descriptions. These descriptions do not capture the dynamics in trace gas emissions that are observed during burning and are not linked to known physical and chemical combustion processes. As the incidence of bushfires and the need for hazard reduction burns in or near urban areas grows, there is a need for incident controllers and planners to be able to assess the impact smoke will have with some accuracy. Therefore, there is a crucial need to be able to model the smoke composition from fires in different vegetation types under different environmental conditions.
Despite of the significance of trace gas emissions on atmospheric chemistry, the process-based understanding of the dynamics of trace gas emissions from vegetation fires is still poorly understood. In order to assess the impact a smoke plume could have on plant and human health downwind of a fire, accurate predictions of the gases in the smoke plume are needed. This project will develop an understanding of the physical and chemical mechanisms by which trace gases are formed temporally during combustion and use this knowledge to develop a predictive model. The student will gain analytical skills in trace-gas analysis such as mass-spectrometry, and will develop skills in numerical modelling. The Faculty of Agriculture and Environment and the Centre for Carbon, Water and Food at the University of Sydney has world-class facilities and capabilities for analysis of trace gases that are not available elsewhere in Australia. In the recent ERA ranking process, the University of Sydney had maximum scores in the fields of Soil Science and Plant Biology and currently boasts five Future Fellows.
