This project aims to develop and translate the first continental-scale tool to address the dynamics of coarse woody debris (CWD: logs, branches and stumps), which are a major source of smoke and fine particle emissions from smouldering combustion during fires. This will be achieved by establishing a spatially explicit, nation-wide dataset of CWD loads and then combining it with process-based biogeochemical modelling, and information on CWD combustion efficiency in relation to size, species and decay classes. The new tool will be used in the Australian Air Quality Forecasting System to deliver an early warning of smoke emissions risk during bushfires and prescribed burns for improved human health, economic and environmental benefits

该项目旨在开发和翻译第一个解决粗木质碎片（CWD：原木，树枝和树桩）动态的大陆规模工具，这些工具是烟雾和湿气燃烧过程中烟气发射的主要来源。这将通过建立CWD负载的空间上明确的数据集，然后将其与基于过程的生物地球化学建模相结合，以及有关CWD燃烧效率与大小，物种和衰减类别有关的信息。该新工具将用于澳大利亚空气质量预测系统，以在丛林大火期间发出烟气排放风险的预警，并开处方烧伤以改善人类健康，经济和环境福利
