Abstract
This report presents data summaries from three networks. Contour maps present NTN data. Concentration and deposition maps present MDN data. The bar graphs present AIRMoN concentrations over time. The NTN maps portray spatial variability in the concentration and deposition of selected acids, nutrients, and base cations on regional and national scales. Only sites that meet prescribed data completeness criteria are included. In 1999, 172 sites met these criteria. Annual concentration or deposition values are printed next to each site. The concentrations are volume-weighted averages. The MDN maps show the concentration and deposition of total mercury in precipitation. Only sites meeting prescribed data completeness criteria are included. In 1999, 33 sites met these criteria. Annual concentration or deposition is printed next to each site. The concentrations are volume-weighted averages. AIRMon data was collected at Penn State University. Among the ten AIRMoN sites active in 1999, the Penn State site was selected because of its central location in the network.
