Thumbnail Image:
Description:
In 2011, NASA’s Applied Sciences Program created the Air Quality Applied Sciences Team, or AQAST, to serve the needs of U.S. air quality management through the use of Earth science satellite data, suborbital data, and models. Satellites are a powerful resource for monitoring changes in air quality. This card shows annual mean satellite observations of tropospheric nitrogen dioxide decrease between 2005 and 2010 as a result of federal and state regulations on emissions.
