New publication in ACPD: Effects of humidity on SOA formation from OH-initiated oxidation of m-xylene - 徐永福课题组

Short Summary: The significantly negative effects of relative humidity (RH) on secondary organic aerosol (SOA) formation from m-xylene under low NOx conditions were observed. The significant RH effects on chemical compositions of SOA are identified, in which highly oxygenated molecules (HOMs) are dominant. Our results show that the decrease of SOA formation under high RH conditions is mainly attributed to the suppression of the formation of oligomers and HOMs.
