摘要：

The configuration of the California Acid Deposition Monitoring Program (CADMP) precipitation network is described and quality assurance results summarized. Comparison of CADMP and the National Acid Deposition Program/National Trends Network (NADP/NTN) data at four parallel sites indicated that mean depth-weighted differences were less than 3 mueq l-1 for all ions, being statistically significant for ammonium, sulfate and hydrogen ion. These apparently small differences were 45-30% of the mean concentrations of ammonium, sulfate and hydrogen ion. Mean depth-weighted concentrations and mass deposition rates for the period 1985-1990 are summarized; the latter were highest either where concentrations or precipitation depths were relatively high.
