North American Acid Deposition System (ADS) and its use in spatial analysis
The Acid Deposition System (ADS) for statistical reporting of acid precipitation data has been established by the US Environmental Protection Agency. The ADS data base system provides an integrated centralized data bank for atmospheric deposition data collected by all monitoring networks in North America. An overview of ADS is given. The underlying structure of the system is described, especially as it impacts potential uses of wet deposition data. North American monitoring networks currently participating in ADS are identified and the geographical coverage of sites are shown. Examples of standard statistical summaries available from ADS are given. Isopleth maps for pH, annual deposition of hydrogen, sulfate, nitrate and ammonium ion species for the period July 1980 to June 1981 are used to illustrate spatial analyses utilizing ADS. Spatial analysis is based on a statistical surface estimation procedure called kriging with the resulting surface then contoured. 20 references, 6 figures, 2 tables.
