Short summary
Single-particle measurements from a soot-particle aerosol mass spectrometer were performed to examine the mixing state of aerosol particles in an air mass influenced by aged biomass burning. Our observations indicate non-uniform mixing of particles within a biomass burning plume in terms of molecular weight and potassium content, and illustrate that high molecular weight organic compounds can be a key contributor to low-volatility BrC observed in biomass burning organic aerosols.
