National Park Service Web Cameras

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.

Here's the one for Washington, DC. Right now, I'd rather be in Denali.

We're doing better today--air quality forecast says code yellow (for particlate matter), which may not be great but isn't likely to kill anyone.
