Abstract |
The National Dry Deposition Network (NDDN) was established to provide long-term estimates of dry acidic deposition across the continental United States. Fifty routine sites were operational from 1990 to 1992, including 41 sites in the eastern United States and 9 sites in the western United States. Each site was equipped with sensors for continuous measurements of ozone and meteorological variables required for estimation of dry deposition rates. Weekly average atmospheric concentrations of particulate sulfate, particulate nitrate, particulate ammonium, sulfur dioxide, and nitric acid were measured at all sites and wet deposition of acidity and related species were measured at selected sites. Two methods development sites were installed during 1991 to evaluate: (1) comparability of United States and Canadian air quality measurements, and (2) effects of terrain on pollutant concentration and deposition. Routine application of an inferential model for calculation of deposition velocities and dry deposition fluxes was also begun. |
