Acid precipitation in North America: 1983 annual data summary from acid deposition system data base

摘要: The report gives a summary of 1983 wet deposition precipitation chemistry data collected in North America and available the Acid Deposition System (ADS) base. American monitoring networks with ADS are NADP/NTN, CANSAP, APN, UAPSP, MAP3S/PCN, WISC, APIOS. An overview each network is given. Annual statistical summaries for provided pH, specific conductance, hydrogen ion (derived from pH), species sulfate, nitrate, ammonium, calcium, chloride, sodium, magnesium potassium. Based on annual summaries, spatial isopleth maps constructed weighted mean nitrate ammonium concentrations, hydrogen, sulfate species.
