This page houses information related to the RAQC’s work around air quality data, modeling, and technical analysis to support air quality planning. Tracking and modeling ozone concentrations are essential to ensure that air quality planning decisions are backed by science and to estimate and monitor progress towards air quality goals.
The RAQC utilizes data from several ozone monitors around the Denver Metro/North Front Range region to track when and where ozone concentrations fall under or exceed air quality standards and goals. Ozone summary tables are updated weekly during Ozone season, which runs from approximately May to September. The most recent summary table is on the Current 8-Hour Ozone Summary page. Historic summary tables are also available. While this information is intended for longer-term tracking and analysis relevant for State Implementation Plans for ozone and overarching air quality planning, the RAQC also provides daily ozone air quality alerts and advisories through its Simple Steps. Better Air. program.
The Colorado Department of Public Health and Environment’s Air Pollution Control Division (APCD) also provides air quality data and information to the public. These include Denver/Front Range air quality forecasts, a Colorado Smoke Blog, maps, daily ozone email alerts, and more.
To aid in evaluating the impact of emissions control strategies as well as developing Attainment Demonstrations as part of SIP requirements for U.S. EPA, the RAQC also engages in air pollution modeling efforts called photochemical modeling in collaboration with the APCD. The RAQC’s emissions and ozone air quality modeling efforts include reports and dashboards related to current and past SIP planning processes as well as information from its Attainment Planning forum meetings, which provide an opportunity for stakeholders and the public to engage.
