| Description | An empirical model of $O_{3}$ is developed using the measurements of emissions of biogenic volatile organic compounds (BVOCs), $O_{3}$ concentration, global solar radiation, photosynthetically active radiation (PAR) and meteorological variables in a subtropical Pinus plantation, China, during 2013–2016. In view of the different structures of isoprene and monoterpenes, two empirical models of $O_{3}$ concentration are developed, considering PAR absorption and scattering due to gases, liquids and particles (GLPs), as well as PAR attenuation caused by $O_{3}$ and BVOCs. The estimated $O_{3}$ is in agreement with the observations, and validation of the $O_{3}$ empirical model is conducted. $O_{3}$ concentrations are more sensitive to changes in PAR and water vapor than S/Q (horizontal diffuse to global solar radiation) and BVOC emissions. $O_{3}$ is positive to changes in isoprene emission at low light and high GLPs, or negative at high light and low GLPs; $O_{3}$ is negative to changes in monoterpene emissions. $O_{3}$ are positive with the changes of PAR, water vapor and S/Q. It is suggested to control human-induced high BVOC emissions, regulate plant cutting, and reduce NOx and $SO_{2}$ emissions more strictly than ever before. There are inverted U-shape interactions between $O_{3}$ and its driving factors, and S/Q controls their turning points. |
