Hygroscopicity of aerosol generated from burning two different forest fire fuels
The figure shows data from smoke aerosols. The left hand plots show relative chemical composition from electron microscopy, while the right hand plots show aerosol particle growth as a function of humidity as measured by nephelometry. Note the top set of plots depict a non-hygroscopic aerosol dominated by carbon, while the lower set of plots show an aerosol which takes up significant water and is composed of significant quantities of inorganic species. In this study we have shown that aerosol water uptake is dominated by the inorganic component of smoke aerosols.
