摘要

At the surface,tropospheric ozone is an air pollutant that adversely impacts human health,natural vegetation and crop yield and quality.This important trace gas also plays key roles as a greenhouse gas,and as the primary source of the hydroxyl (OH) radical,which determines the lifetime of many other trace gases in the atmosphere.Tropospheric ozone has a variety of sources including photochemical production from anthropogenic and naturally occurring precursor gases,and transport from the stratosphere.As a result of its high reactivity and its wide range of sources,ozone's lifetime can vary from minutes in the polluted boundary layer to several weeks in the mid-and upper troposphere.
