Abstract
A measurement campaign was performed in two large cities in China, Beijing and Guangzhou, to investigate biogenic emissions of volatile organic compounds (VOCs) using a GC‐FID system and the enclosure chamber technique. Four typical types of trees, namely pine, cypress, poplar and Chinese‐scholar tree were studied. The influences of temperature and light intensity on VOC emissions were analyzed using algorithms derived from what is currently understood about VOC emission mechanisms. Biogenic VOC emission fluxes in these two cities were estimated. A 2‐D air quality model was developed to assess the role of biogenic VOC emissions in the ground‐level ozone formation in Beijing and Guangzhou.
