* Ozone values above 84 ppb exceed the ozone National Ambient Air Quality Standard of 0.08 ppm.
† Eighteen health advisories were issued at Rocky Mountain National Park based on Colorado Department of Public Health and Environment advisory forecasts. There was one event when the ozone 8-hr average was greater than 84 ppb at the Park
