Abstract
It is understood that a significant portion of secondary organic aerosol (SOA) mass in the atmosphere is a direct product of volatile organic compound (VOC) oxidation. Previous studies that explored the new particle formation (NPF) of SOA reported contradictory results regarding the NPF with respect to relative humidity (RH). However, studies from our group indicated that at lower mixing ratios [VOC/ozone], and at 60 % RH, the NPF of α-pinene-derived SOA was significantly enhanced. The purpose of this study is to examine the potential enhancement of NPF from cis-3-hexenyl acetate (CHA)-derived SOA with respect to RH at varying mixing ratios.
