Atlanta's Decrease in NO2

Caption

Satellite data show that Atlanta has seen a 42 percent decrease in nitrogen dioxide between the 2005-2007 (left) and 2009-2011 (right) periods. Technology improvements, such as the implementation of emission control devices on power plants, mean that residents here are now breathing cleaner air.
