About the Air
Quality Index (AQI)
About Pollution Levels at this Village Green Bench
This Village Green bench shows air quality two ways. The blue scale shows minute-by-minute pollution levels right at this bench. The blue scale tells you if pollution is low, medium or high.
The multi-colored scale shows current air quality as the Air Quality Index (AQI) for your general area. The AQI is based on data from official, highly-accurate, government monitors that measure over a larger area than the sensor at this bench. The AQI provides information about steps you can take to protect your health.
