Short summary
Wildfire plumes in the western US were sampled at a high-elevation site in summer 2013. Three distinct BBOA types were identified, representing biomass burning OA with different degrees of atmospheric processing. Analysis of consecutive BB plumes transported from the same fire source showed that photooxidation led to enhanced mass fractions of aged BBOAs but negligible net OA production. A possible reason is that SOA formation was almost entirely balanced by BBOA volatilization during transport.
