Short summary
Organic aerosol is a dominant component of atmospheric aerosol worldwide, and it is recognized as a key factor affecting air quality and possibly climate. We revealed the aqueous secondary organic aerosol formation and brownness from aged biomass-burning emissions and highlighted the importance of aqueous-phase reactions on air quality and climate. The aqueous secondary organic aerosol from aged biomass-burning emissions should be taken into account in air quality and climate models.
