Clean air is vital to human health and well-being. Clean air allows people to breathe easy, experience clear views that inspire and nurture the human spirit, and keeps ecosystems healthy. Every national park has air resources, and everyone who breathes, enjoys looking out across our treasured lands, and cares about having healthy ecosystems is affected by air quality.

The Air Resources Division (ARD) is comprised of air resource experts, from scientists to policy analysts, dedicated to achieving and maintaining clean air in all units of the National Park System. ARD is part of the Natural Resource Stewardship and Science Directorate of the National Park Service. The division's home base is Colorado, with a network of air resource coordinators serving every region of the service.
