Recent Air Pollution Reduction Improves Parks
Air quality and visibility have improved dramatically at national parks and other areas of national scenic value in association with reduced air pollution emissions, according to new data analysis by the Cooperative Institute for Research in the Atmosphere at Colorado State Univ.
Using atmospheric conditions from the 1990s and present day, CIRA researchers can simulate what the parks looked like then and now.
“The simulated images illustrate that at places such as Great Smoky Mountains National Park, mountains that were once regularly obscured by haze are now clearly visible,” says Jenny Hand, a CIRA scientist who is working with the National Park Service to study air pollution trends and their causes.
