This study surveys and summarizes current knowledge about the role of oxides of nitrogen (NOx) in the formation of ozone (O3) in nonurban areas. Project elements include a literature review, a survey of expert opinion, and analyses of field data. The results of the study show that present knowledge about NOx/O3 interactions in nonurban areas is fragmentary, and that there is no direct quantitative description of the link between urban NOx and nonurban O3. A preliminary analysis of nine rural and suburban sites indicates that transport is the principle mechanism associated with ozone levels that exceed 100 ppb. The analysis further suggests that transport times of the order of six to eight hours are most likely to be associated with the high ozone observed at these sites.
