The U.S. Environmental Protection Agency (EPA) unveiled the new “Air Emission Sources” Web site today. It is designed to make emissions data for six common pollutants easy to find and understand. Based on the latest National Emissions Inventory, the site uses charts and Google Earth files to answer a user’s questions. Users can look at overall emissions, emissions by type of industry, or emissions by largest polluter.
Want to know what industry emits the most sulfur dioxide in your state? Select your state from a map, pick a pollutant, and the site creates a chart showing you emissions by industry. Want to “see” which refineries in your state emit the most sulfur dioxide? Use the “tilt” feature in Google Earth to quickly find the largest emitter. Then click on the balloon to get more details about emissions from that facility.
The EPA is also providing Air Quality Index (AQI) information in the Google Earth format. Use the AQI tool to quickly see air quality across the country, then click on a specific location to see that city’s AQI forecast and current levels of ozone or particle pollution. You can manipulate the parameters for output in Google Earth format at http://www.epa.gov/air/emissions/where.htm

EPA is also using the Google Earth platform to display Acid Rain Program data: http://epa.gov/airmarkets/progress/interactivemapping.html
