The National Park Service operates digital cameras at many parks to help educate the public on air quality issues. These cameras often show the effects of air pollution such as visibility impairment. Because these cameras are typically located near air quality monitoring sites, the camera web pages display other information along with the photo such as current levels of ozone, particulate matter, or sulfur dioxide air pollutants, visual range, and weather conditions.The digital photos are usually updated every 15 minutes, while air quality data values are revised hourly.Click on a park name in the map below to check its current visibility and air quality.
