 AQI Plot

Compare AQI values for multiple pollutants for a specific location and time period. This tool displays an entire year of AQI values – two pollutants at a time - and is useful for seeing how the number of unhealthy days can vary throughout the year for each pollutant.

Note: As of March 18, 2013, all PM2.5 AQI values and summaries provided by AirData reflect the recently updated AQI breakpoints. For a fact sheet on the revised PM2.5 standards and updated AQI breakpoints, visit: http://www.epa.gov/airquality/particlepollution/2012/decfsstandards.pdf
