Air Quality in Parks

Over the last 30 years air quality has improved significantly in national parks and across the U.S. This is great news because parks need clean air. It is essential for the health of our visitors and employees, clean clear views of park scenery, and a healthy natural environment. But, we also know that almost all national parks are still affected by air pollution.

One way we keep up with the changing air quality in parks is by monitoring and looking at air data in different ways.
