How Do We Know What the Air Quality Is?

The Maricopa County Air Quality Department operates nearly 25 ambient air monitoring stations within the county.  Data is taken from those sites and used with current and forecast weather conditions to determine the daily air quality forecast.

The best way to protect your health and the health of your family is to familiarize yourself with the Air Quality Index (AQI) which has the following colored indicators of air quality:

  1. Green (good)
  2. Yellow (moderate)
  3. Orange (unhealthy for sensitive people)
  4. Red (unhealthy)
  5. Violet (very unhealthy)
Here is a List of Recommendations for Each Range in the AQI
  1. Good: No restrictions on outdoor activities.
  2. Moderate: Outdoor activity is reasonable though people should be cautious of weather conditions and pollutants in their area. Check the current air quality status here.
  3. Unhealthy for sensitive people: Outdoor activity should be limited. People with respiratory problems or young children with developing lungs should stay indoors.
  4. Unhealthy: Outdoor activities for all persons should be limited.
  5. Very unhealthy: Outdoor activities are not recommended for any population.

Clean Air Make More is an educational outreach initiative created by the Maricopa County Air Quality Department to inform Maricopa County residents about air pollution challenges we face in the county and provide them with the tools they need to take action.  There are several interactive tools citizens can utilize to help keep our air clean.
