Abstract A 1,000,000 sq km area of the Eastern United States had sulfate concentrations exceeding 10 microgram/cu m on July 10, 1974, and there were indications that parts of the area had high concentrations on prior days. The meteorology associated with the high concentrations and correlations of high ozone and sulfate concentrations are discussed. It appeared that slow moving and subsiding air contributed to the high concentrations of both pollutants. Long range transport, as shown by trajectory analyses, was a factor in the problems in most areas, but the worst situations with regards to sulfates were associated with emissions from nearby, upwind sources. While high ozone concentrations were observed immediately prior to high sulfate concentrations in many areas, there were high sulfate concentrations that were not associated with high ozone concentrations. In the latter situation, the high sulfate concentrations were associated with air which had earlier movement over areas with high SO2 emission.
