AirExplorer | US EPA

Air Explorer is a collection of user-friendly visualization tools for air quality analysts. The tools generate maps, graphs, and data tables dynamically. Currently, the tools access ambient concentration data from EPA’s Air Quality System (AQS). The criteria pollutant data were last updated on April 17, 2008. PM2.5 speciation data were last updated on November 2, 2006.

UPDATE (8/22/2008) The PM2.5 speciation data were updated to include data through 2007.
UPDATE (7/3/2008) The AQI graphics now reflect the new ozone AQI break points.
UPDATE (4/17/2008) The criteria pollutant data were updated to provide complete years for 1997 to 2007.
