Short summary
A fall field campaign was conducted at a national background site (3295m a.s.l.) over the Tibetan Plateau. The submicron aerosol was dominated by organics (43%) and sulfate (28%). Secondary organic aerosol (SOA) dominated OA (85%), 17% of which being aged biomass burning OA. New particle formation and growth events were frequently observed, with an average particle growth rate of 2.0nm per hour. The important role of organics in particle growth in the Tibetan Plateau was also demonstrated.
