✦ Synopsis

An overview of the role of NO x in the formation of rural 03, regional transport and its potential impact on urban air quality is presented. An analysis of a specific O3 excursion in southeast Michigan (8-2-90) is performed based on a combined urban and regional-scale model. The regional component of the model represents transport and photochemistry from sources as far away as Texas. Results suggest that rural 03 and regional transport sensitive to NO x emissions and relatively insensitive to changes in volatile organic carbon (VOC) emissions. This differs from the situation in urban areas, where 03 is sensitive to both NO x and VOC. Regional transport and upwind NO x emissions have a significant impact on peak 03 in Detroit. Implications for urban and regional-scale abatement strategies are discussed.
