Boulder and Fort Collins have unusually high ozone levels as well. Gasoline is one culprit.

Ozone is created when the sun bakes common pollutants such as engine exhaust, wildfire smoke and vapors from everything from paint cans to oil and gas wells.

State health officials ask people to do little things, such as not spilling gasoline at the pump, waiting to refuel until after dusk, when the vapors have less time to cook into ozone, and trading in old gasoline-powered mowers for newer models.

The national air quality index is here. Forecasts for Denver today and tomorrow are here.
