| Abstract: | A statistical analysis of the precipitation data base from the Integrated Lake-Watershed Acidification Study (ILWAS) is presented. Included in this analysis are: equivalence of distributional form of the concentrations, ion pair concentration analysis, regression by site and season, precipitation type, and multiple regressions. The analysis emphasizes the ions: H, NH4, SO4, and NO3. Variability in H is explained largely through SO4 and NO3; spatial variability for the species pairs SO4-H, NO3-H, SO4-NH4; and NO3-NH4 does not suggest significant differences between sites on a seasonal basis. |
