National Park Service Web Cameras

Overview

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.

NEW!  Charts of the last ten days of hourly weather, ozone, particulate matter, or sulfur dioxide data are now available. To view, click the blue "10-day Charts" tab now appearing on the right side of each park's web camera home page.

The digital photos are usually updated every 15 minutes, while air quality data values are revised hourly.

Hawaii Volcanoes National Park does not operate a web camera but does post near real-time levels of sulfur dioxide resulting from volcanic emissions. Such emissions can be harmful at times to park visitors and staff.
