Popis:	The influences of meteorological factors on precipitation acidity and constituent concentrations were investigated statistically using selected portions of a new archive of daily precipitation chemistry measurements for the eastern United States. This archive consists of measurements from networks operated by the Electric Power Research Institute and Utility Acid Precipitation Study Program (EPRI-UAPSP), the Multistate Atmospheric Power Production Pollution Study (MAP3S), and the Wisconsin Acid Deposition Measuring Programs (WADMP) during the period 1979 through 1983. Differences in acidity and analyte concentrations were found for different precipitation types. Rain had significantly higher average acidity, and higher sulfate and ammonium concentrations than frozen precipitation, while the latter had the highest nitrate concentration. Precipitation days were classified objectively into seven groups including warm frontal, cold frontal, and convective categories. On an overall basis for six sites...
