Question 1

What is the Air Quality Index (AQI)?

Accepted Answer

The AQI is a measure used to communicate how polluted the air currently is or how polluted it is forecast to become. It converts complex pollutant data into a simple number scale from 0-500.

Question 2

What pollutants are measured?

Accepted Answer

The AQI typically measures PM2.5, PM10, ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO) concentrations in the air.

Question 3

What do the AQI categories mean?

Accepted Answer

AQI categories range from Good (0-50) to Hazardous (301-500). Higher values indicate greater pollution levels and increased health risks for sensitive groups.
