AB: The oxidation of volatile organic compounds (VOCs) in the presence of nitrogen oxides leads to the formation of ozone in the troposphere. Besides ozone, other secondary species such as carbonyls and organic nitrates are formed that are characteristic of the parent VOC species. Ambient measurements of secondary species reflect the integrated effect of emissions, photochemical production and loss, as well as other removal processes. Analysis of ambient measurements of select secondary species that were made during recent field experiments are used here to evaluate the understanding of tropospheric photochemistry.
