Air Atlas
Use the navigation links on the top right under Highlights to access the combined the ozone, sulfate/nitrate, visibility, wet deposition and dry deposition maps. The combined data is displayed for two separate time periods.
All the pollutant maps are presented as 5 or 6 year climatologies to avoid the natural year-to-year variations. The focus is on rural locations; all the monitoring networks, except for ozone, are predominately in non-urban sites. Our experience is that in urban areas and near pollutant sources, specific nearby monitors are more accurate than the interpolations from the rural monitoring networks.
This Air Atlas project is a partnership between Dr. Paul Sutton, University of Denver, Geography Department, and Dr. John D. Ray at the National Park Service, Air Resources Division, Research and Monitoring Branch. Questions or comments?: Dr John Ray 303-969-2820.
