Abstract:The 2019-2020 Australian bushfire season was historically large, long, and intense. Smoke from fires burning in southeast Australia blanketed population centres for weeks to months. This study reports the chemical composition in the gas and aerosol phase of aged plumes measured near Wollongong, NSW in early 2020. Enhancement ratios to CO are presented for thirteen species. Plume composition is largely similar to that measured in fresh smoke during previous studies. It is hoped enhancement ratios reported here … Show more
