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 criteria pollutant concentration data from EPA’s Air Quality System (AQS) Data Mart. PM2.5 speciation data are post-processed from AQS and were last updated on November 2, 2006.

UPDATE (11/13/2009) All tools (except those that access PM2.5 speciation data) are now connected directly to the AQS DataMart.
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.
