A spruce-fir forest in central Maine, USA, has been the site of dry and wet atmospheric deposition measurements since 1988. Precipitation flux of hydrogen ions and sulfate decreased by 24 and 43%, respectively, during the study period, but temporal trends occurred for precipitation H+ or SO2/4 concentrations. Decreased precipitation fluxes were likely due to a 33% decrease in precipitation amounts during the latter years of the study.
