Seilkop, S K; Finkelstein, P L

Using data compiled from seven nationwide precipitation chemistry networks in the U.S. and Canada, the spatial distribution of hydrogen, sulfate, and nitrate ions in North America is discussed. Geographic patterns of concentration and deposition are characterized using isopleth maps which are presented and interpreted for the years 1980, 1981, and 1982. The maps were developed using a geostatistical technique known as kriging. This method allows for the estimation of confidence limits on interpolated values. Using these limits, the significance of temporal changes in spatial patterns of deposition and concentration is assessed. The data discussed in the presentation were compiled and initially summarized by Battelle Northwest Laboratories in the operation of the Environmental Protection Agency's Acid Deposition System (ADS).
