Atlas of Air Quality and Deposition in or Near Forests of the Western United States

摘要

An atlas of air quality and deposition data has been compiled to make air pollution data and information more accessible to biologists and ecologists working in western forests. Data from the 1985 National Acid Precipitation Assessment Program Emission Inventory are used to characterize emissions of sulphur dioxide and nitrogen oxides across the West. Maps illustrating location, type, and magnitude of major point source emissions together with pie charts of the percent contribution by source category are presented alphabetically by state. Data from the Environmental Protection Agency databases AIRS and SAROAD are used to characterize ambient levels of sulphur dioxide and ozone for three averaging periods, viz., annual, May through October or growing season, and monthly. Data for 20 sulphur dioxide and 70 ozone sites in or near western forests are presented by state. Biographic information together with standard summary statistics are given for each site.
