Abstract: Sulfate levels in Boston, Mass. demonstrated a high correlation with meteorological parameters indicative of long-range transport of aerosols. Two-hour average samples of total sulfate and total suspended particulate were collected at three urban sites. Meteorological data including barometric pressure, absolute humidity, and wind direction were obtained for each sampling interval. High correlations between sulfate levels and the meteorological variables support the hypothesis that elevated sulfate levels in the northeast are derived from atmospheric reactions associated with long distance transport of particulate-laden air masses. A sulfate prediction model based on multiple linear regression is presented.
