Description:
The report gives a summary of 1985 wet deposition precipitation chemistry data collected in North America and available in the Acid Deposition System (ADS) data base. North American wet deposition monitoring networks with data in ADS are NADP/NTN, CANSAP, APN, UAPSP, MAP3S/PCN, WISC, and APIOS. An overview of each network is given. Annual statistical summaries for 1985 are provided for pH, specific conductance, hydrogen ion (derived from pH), and the ion species sulfate, nitrate, ammonium, calcium, chloride, sodium, magnesium and potassium. Based on the annual summaries, 1985 North American spatial isopleth maps are constructed for precipitation weighted mean pH, sulfate, nitrate, and ammonium ion concentrations, and annual deposition of hydrogen, sulfate and nitrate and ammonium ion species.
