Values are the US EPA Air Quality Index, calculated from the 1-hour average PM2.5 reading. A monitor that has not reported in 24 hours shows as Offline, and one reporting an impossible value as Sensor error. In both cases the last reading is hidden rather than shown as good air quality.

About CALs

Community Air-Quality Levels (CALs) are used to describe air quality in terms of how harmful the level of particulate matter (PM) pollution in the air is to human health. The CALs are derived using similar methods as EPA’s Air Quality Index (AQI).

You should use both IVAN Air Monitoring and government air data to understand the air quality levels around you. When comparing health recommendations from both sources, you should follow the most health protective recommendation.

*Sensitive groups include children, teens, older adults, pregnant women, and people with heart, lung, or other chronic diseases

Government air data

Data reported by IVAN Air Monitoring and by government monitors should both be used to better understand air quality levels near you. There are differences in how these data are collected, such as the locations monitored, the equipment used, and pollutants measured. Therefore, differences in reported air data are expected. When considering how to best protect your health, we recommended you consider multiple sources of air quality data and follow the most health protective recommendations.

Visit the Air Monitoring FAQs for more information about how our data compares with government data.
