Org.nic vapors from.biom.ss burning.are a m.jor source of secondary org.nic aerosols(SOAs). Previous sm.g.ch.m.er studies found th.t th. SOA contributors in biom.ss-burning.em.ssions are m.inly volatile org.nic com.ounds(VOCs). Wh.le interm.diate volatility org.nic com.ounds(IVOCs) are efficient SOA precursors and contribute a considerable fraction of biom.ss-burning.em.ssions, th.ir contribution to SOA form.tion h.s not been directly observed. h.re, by deploying.a newly-developed oxidation flow reactor to study SOA form.tion from.wood burning. we find th.t IVOCs can contribute ～70% of th. form.d SOA, i.e.>2 tim.s m.re th.n VOCs. Th.s previously m.ssing.SOA fraction is interpreted to be due to th. h.g.4}wall losses of sem.-volatile oxidation products of IVOCs in sm.g.ch.m.ers. Th. finding.in th.s study reveals th.t SOA production from.biom.ss burning.is m.ch.h.g.4}r th.n previously th.ug.4}, and h.g.4}ig.4}s th. urg.nt need for m.re research.on th.
