Understanding Air Quality Index (AQI)

The Air Quality Index (AQI) is an important metric that helps individuals understand outdoor air quality. It combines multiple pollutants, including particulate matter and gases like nitrous oxide, to indicate the overall air quality level. The AQI is color-coded, allowing users to quickly assess conditions: green and yellow signify good air quality, while red and purple indicate poor quality where precautions like wearing masks may be necessary. Monitoring the AQI, especially during wildfire seasons, is crucial for maintaining health and safety outdoors.
