Short summary
We investigated the influence of relative humidity (RH) on the heterogeneous oxidation of secondary organic aerosol (SOA) particles by OH radicals. We observed significantly faster volume loss and compositional change of SOA at high RH, showing that viscosity differences determine compositional changes, but variability in either the uptake coefficient or the fragmentation probability are required to explain the difference in volume loss between low and high RH.
We investigated the influence of relative humidity (RH) on the heterogeneous oxidation of...
