The Air Quality Index, or AQI, is a way to measure air pollution levels ๐ก๏ธ. It ranges from 0 to 500, showing how clean or polluted the air is. A lower AQI means cleaner air, while a higher number indicates more pollution. For example, an AQI of 0-50 is considered good (green), while 151-200 is unhealthy (orange) ๐. The AQI helps us know when it's safe to play outside or when we should stay indoors. Cities often display AQI levels in public spaces, so everyone can stay informed! ๐
