| 摘 要： | The effect of soil NO emissions on surface ozone in autumn in East China has been studied byusing TCTM(Troposphere Chemical Transport Model)with the input of meteorological variablesfrom RAMS.The chemical mechanism for ozone variation caused by soil emissions has also beeninvestigated.The model results reveal that soil NO emissions are important to regional ozoneformation and distribution and the effect of soil NO emissions shows spatial inhomogeneity.Ozoneover most areas in northern China decreases with maximum average decrement reaching 5 ppbwhile it increases over most areas of central and southern China with maximum average incrementreaching 7 ppb caused by soil NO emissions.This situation of ozone variation is mainly determinedby nonlinear photochemical mechanism.For the low NOx areas(≤3 ppb),ozone increases as NOxincreases;for the high NOx areas(>3 ppb),ozone decreases as NOx increases.The effect of soilNO emissions on ozone depends on the transition value and NOx concentrations.
