Potential effect on aerosol formation by diterpene emissions from dominant coniferous trees (Cryptomeria japonica and Chamaecyparis obtusa) in Japan

Abstract

Recent decades, many efforts have been made to investigate biogenic volatile organic compounds (BVOCs) due to their significant impact on atmospheric chemistry and physics. On the other hand, atmospheric modeling studies have suggested that there is likely to be significant amount of unknown reactive organic compounds in the atmosphere. In this study, we focused on high molecular weight BVOC such as BVOC larger than C15 emitted from the most and 2nd dominant coniferous trees in Japan and have conducted field campaigns at two different sites. As a result, significant emissions of diterpenes have been discovered. I would like to present about the significant emission of the diterpenes and their potential impact on atmospheric chemistry and aerosol formation.
