Abstract Regional patterns in air quality across the coniferous forests of the West are investigated using public data bases (NADP/NTN and AIRS). The results indicate that regional air pollution levels are low but that local airsheds can be highly polluted. Sulfur dioxide levels are generally less than 30 ppb, with maximum concentrations during the winter. High concentrations of sulfur dioxide have been measured in forests close to point sources. Ozone concentrations are usually less than 80 ppb, but often exceed the Federal Standard in areas downwind of large urban and industrial centers during summer months. Acid deposition levels are 15-20% of those in the east, but cloudwater chemistry is more comparable, especially in southern California.
