DeMarrais, G. AND D. Coventry. ANALYSIS OF HIGH SULFATE CONCENTRATIONS IN GREATER NEW YORK CITY AIR. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/4-79/074 (NTIS PB80128515).
Description:
The meteorological phenomena occurring during April 15 to 21, 1976, when high sulfate concentrations were measured in the New York City area, are summarized. Findings of earlier investigations of relationships between meteorological phenomena and high sulfate concentrations are compared to the findings of this investigation. Since ozone readily occurs with the same meteorological conditions than are associated with sulfate episodes, the ozone concentrations are also discussed. Results showed that the current procedure for sampling sulfate every sixth day does not provide sufficient data for adequately determining how sulfate concentrations relate to meteorological phenomena. The sampling schedule only allows for indicating what the meteorological conditions were when the concentrations were a certain value and not how the concentrations changed with changing meteorological conditions.
