The AQI is an index for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The Air Quality Index ( AQI ) is used for reporting daily air quality. This report provides Air Quality Index annual summary information, including maximum AQI values and the count of days in each AQI category.
Use the query tool below to get AQI reports for one state, county, or CBSA at a time. Click this link if you want a national file that lists all counties or CBSAs. AIR QUALITY INDEX Numbers in the chart above show the Air Quality Index for today, based on an average over time.
See AQI Table for how to interpret the colors. The Index numbers represent a ranking for the pollutant, not the measurement of a pollutant. Most of the stations on the map are monitoring both PM 2.

AQI: Unhealthy for Sensitive Groups (1- 150) Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.

This scale is based on the National Ambient Air Quality Standards (NAAQS) and is described in the Code of Federal Regulations, Part 5 Appendix G. Taken together, concentration and time represent the dose of the air pollutant.

Health effects corresponding to a given dose are established by epidemiological research.
