| 説明 | Pollution builds up along the U.S. East Coast as it passes from one city to the next, particularly in the Northeast Corridor. These cities include Richmond, Washington, D.C., Baltimore, Philadelphia, New York City, Boston and all the smaller cities in between. Some of the largest absolute changes in nitrogen dioxide have occurred in this corridor. This visualization shows tropospheric column concentrations of nitrogen dioxide as detected by the Ozone Monitoring Instrument on NASA's Aura satellite, averaged yearly from 2005-2011. Blue and green denote lower concentrations and orange and red areas denote higher concentrations, ranging from 1x1015 to 5x1015 molecules per square centimeter, respectively.
