It is increasingly apparent that urban, regional, and global scale environmental problems are coupled and cannot be arbitrarily separated. Most all of the major western cities now suffer from brown cloud problems. The degradation of visibility from the interactions of aerosols and gases with the incoming solar radiation has been the major focus of the research on these problems. They authors are just beginning to appreciate that these problems are coupled with oxidant issues, as well. For example, secondary aerosols are produced from oxidation reactions involving gas phase species, as well as aqueous oxidation reactions and will contribute to the visibility degradation. This work presents data for NO{sub 2} and peroxyacetyl nitrate levels measured in Albuquerque, NM during the winter of 1988 using correlation spectrometry and gas chromatography/electron capture detection, respectively. These data indicate that the photochemical oxidation of sulfur dioxide and other materials will contribute secondary aerosols to the urban environment, even in the wintertime. Aqueous production on wet aerosols and in fogs and clouds may also be important as peroxide production will be coupled to the gas and aqueous phases. In many of the mountain states, the effect of changing albedo needs to be taken into account when dealing with these situations, particularly for those urban centers where snow cover can be appreciable in the winter. Various control strategies will be discussed in terms of the coupled oxidative gas phase and aerosol phase chemistry and physics. The need for simultaneous aerosol and gas phase measurements in brown cloud studies will be addressed.
