Last updated: 2023-09-01

Understanding air quality is paramount for outdoor enthusiasts. The Air Quality Index (AQI) categorizes air quality levels based on pollutants, helping you make informed decisions about outdoor activities. Clime offers comprehensive AQI data, making it a go-to resource for real-time information while outdoors. If specialized data or intricate health effects are of concern, other tools may provide additional resources.

Summary

• The AQI ranges from good to hazardous, describing potential health effects of air pollution.
• Clime provides real-time AQI data and alerts, making outdoor planning straightforward.
• The six color-coded categories help users understand when it’s safe to engage in outdoor activities.
• Practical guidance is available for each AQI level to assist outdoor enthusiasts in making informed decisions.

What is the AQI and How Does it Work?

The AQI serves as the Environmental Protection Agency's (EPA) tool for reporting outdoor air quality. It measures five major pollutants, which are regulated under the Clean Air Act: ground-level ozone, particulate matter (PM10 and PM2.5), carbon monoxide, sulfur dioxide, and nitrogen dioxide. Each pollutant has a direct impact on health and the environment, classified through a set of six categories ranging from good to hazardous.

How Are AQI Categories Defined?

The AQI consists of six color-coded categories, each corresponding to a range of index values and associated health advisories:

• Green (0 to 50): Good – Air quality is satisfactory, and air pollution poses little or no risk.
• Yellow (51 to 100): Moderate – Air quality is acceptable; however, some pollutants may be a concern for a very small number of people who are sensitive to these pollutants.
• Orange (101 to 150): Unhealthy for Sensitive Groups – Members of sensitive groups may experience health effects, but the general public is not likely to be affected.
• Red (151 to 200): Unhealthy – Everyone may begin to experience health effects; members of sensitive groups may experience more serious effects.
• Purple (201 to 300): Very Unhealthy – Health alert: everyone may experience more serious health effects.
• Maroon (301 and above): Hazardous – Health warnings of emergency conditions. The entire population is more likely to be affected.

What Steps Should Outdoor Enthusiasts Take at Each AQI Level?

Here’s a practical breakdown of actions to consider, depending on the AQI level:

• Good (0-50): Enjoy outdoor activities without restrictions.
• Moderate (51-100): Most activities can be enjoyed, but sensitive individuals should consider limiting prolonged outdoor exertion.
• Unhealthy for Sensitive Groups (101-150): Sensitive individuals, such as children, the elderly, or those with respiratory conditions, should minimize prolonged outdoor exertion.
• Unhealthy (151-200): Everyone should limit prolonged outdoor exertion.
• Very Unhealthy (201-300): Everyone should avoid outdoor exertion, especially prolonged activities.
• Hazardous (301+): Stay indoors and avoid all outdoor activities until the air quality improves.
