North American Air Quality Index Offers Real-Time Monitoring

AirNow.gov provides continuous updates on air quality across the United States, Canada, and Mexico. The Air Quality Index (AQI) uses a color-coded system to categorize pollution levels from 'Good' to 'Hazardous', with hourly data. This system helps identify areas with elevated ozone and particle pollution. The public is encouraged to regularly check local conditions due to potential health concerns, particularly for vulnerable populations.
