Cumulative exposure to smoke is an important public health metric. This report summarizes the cumulative number of days air quality monitors in New York spent in each AQI category during the the month of November.

The tables below include only permanent monitors measuring PM2.5 and show cumulative exposure under existing NAAQS (National Ambient Air Quality Standards) and under the 2024 revised standards for PM2.5.
