A network of five atmospheric aerosol samplers was established in the northeastern US starting in February 1977. Size-fractionated samples of the aerosol were collected continuously with four-hour time resolution until the network was dismantled in February 1980. The aerosol-loading and aerosol-chemistry data obtained over this three-year period are summarized in this report. In particular, the samples were analyzed for the sulfate acidity of the aerosol. The acidity was found to be quite high over prolonged periods of time, with the monthly averaged acidity approaching that of ammonium bisulfate at several of the sites. Monthly, seasonal, daily, and diurnal variations in aerosol particle loading and acidity, and sulfate, ammonium, and nitrate ion concentrations are presented. The aerosol-chemistry data are tabulated separately for each of the sampling sites.
