Ozone absorbs ultraviolet light which is harmful to life. However the recent increase in ambient ozone level due to climate change is becoming the cause of stimulating the human eye, affecting the respiratory system, and damages the crops. In this paper, a study was conducted at the Taehwa Research Forest (TRF) in Seoul National University with the purpose of analyzing the characteristics of forest air chemistry based on the measurement of Biogenic Volatile Organic Compounds(BVOCs) emitted from forests and to investigate the correlation of BVOCs with ozone generation. Ozone was high from the middle of May to the middle of June, which was before the rainy season. Comparison of the correlation between ozone and isoprene during the measurement period in TRF showing NOx limited showed that the R2 was correlated with a low value of about 0.4. However, when the isoprene is actively produced from 6:00 AM to 18:00 PM, correlation analysis showed that R2 was about 0.9, while monoterpene started to increase in the afternoon and monoterpene decreased ozone at night. Correlation analysis showed negative correlation. Forests have two characteristics, not only the formation of ozone but also the decomposition of ozone.
