Smoldering coarse woody debris and air quality

该项目旨在开发和翻译第一个大陆尺度的工具，以解决粗木屑（CWD：原木，树枝和树桩）的动力学问题，这是火灾中闷烧燃烧产生的烟雾和细颗粒排放的主要来源。这将通过建立一个空间明确的、全国性的CWD负荷数据集，然后将其与基于过程的生物地球化学模型以及CWD燃烧效率与尺寸、物种和衰变类别相关的信息相结合来实现。新工具将用于澳大利亚空气质量预报系统，在森林火灾和规定燃烧期间提供烟雾排放风险的早期预警，以改善人类健康、经济和环境效益

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
