Hourly precipitation samples were collected at Brookhaven National Laboratory with the Brookhaven Automatic Sequential Precipitation Sampler from June 1976 through September 1983. Conventional meteorological data and the synoptic conditions causing the precipitation were recorded for each hourly sample period. The samples were analyzed for pH, conductivity, and concentrations of sulfate, nitrate, ammonium, sodium, and chloride ions until October 1982 and for only pH and conductivity thereafter. Data from a six-year period when complete chemical measurements were performed were selected for analysis. Ratios of selected ions and excess sulfate were calculated and treated as additional variables. Statistical analyses were performed of the relationships between selected chemical variables and between them and meteorological conditions. Precipitation rate and precipitation amount were also analyzed in terms of other meteorological variables. The results, presented in a series of tables, are given for each year separately for unclassified data and for the six years jointly for data classified by meteorological and synoptic conditions. Annual means of ionic concentrations for the five calendar years within the six-year period are also given for comparison with annual data from other stations. 19 references, 5 figures, 18 tables.
