Carbon Monoxide and Light Alkanes as Tropospheric Tracers of Anthropogenic Ozone

Transport of pollutants from populated and industrialized continental areas affects the chemistry and radiation balance of the global troposphere [Duce et al., 1991]. A pollutant of particular interest is ozone (O₃), since its photolysis initiates the oxidizing processes in the atmosphere [Logan et al., 1981], and it is an important greenhouse gas, whose atmospheric trends are only poorly known [Watson et al., 1990]. Thus, the transport of ozone and its precursors from source regions affects the oxidizing capacity of the troposphere in the receptor areas and is important in climate change.
