Short summary
The negative effects of relative humidity (RH) on secondary organic aerosol (SOA) formation from m-xylene under low NOx conditions were observed. The mechanisms of the RH effects of SOA yields have been sufficiently discussed. The decrease of SOA formation at high RH may be mainly attributed to the suppression of oligomers and the further particle-phase reaction of highly oxygenated organic molecules. The faster wall loss of SOA precursors at higher RH may also influence the SOA yield.
