Aerial ozone measurements were obtained during the summer of 1975 in the Northeastern United States. The paper reports on the results of a series of tests conducted upwind and downwind of several major metropolitan and industrial complexes, which include Philadelphia-Camden-Wilmington and New York City-Northeastern New Jersey-Southeastern Connecticut. Flight patterns consisted of upwind and downwind transverses perpendicular to the urban plume and vertical profiles. The results indicate significant O/sub 3/ generation occurs in the urban plumes, but at no time was the difference between the upwind and downwind O/sub 3/ concentrations greater than 0.08 ppM (maximum 0.078 ppM). However, in several cases when the upwind values were added to the O/sub 3/ produced by the urban area, this was sufficient to result in violations of the NAAQS downwind. The paper also discusses the results of flights over refineries and petrochemical facilities which yielded a positive contribution to downwind O/sub 3/ values.
