As we move into the summer season, sunny skies and high temperatures can also be accompanied by high concentrations of ozone. In fact, this afternoon there is an ozone alert for the western areas of Denver and Boulder. Basic facts on ozone can be found on OzoneAware.org, a site created by the Regional Air Quality Council.
The Air Pollution Control Division of the Colorado Department of Public Health and Environment has a lot of useful resources on their website. There is a real-time map of conditions from air monitoring sites around the state, a variety of air quality reports — including data by monitoring site, parameter (temperature, carbon monoxide, ozone, etc.), and tracking air quality over time. Information on ozone alerts and tips for individuals on the prevention of ozone can be found here as well.
Additional resources can be found by searching the State Publications Library catalog using the keywords “ozone” or “air quality.”
