Nitrogen Dioxide from Aura/OMI, 2013-2014

  • Released Monday, March 18, 2013

Major sources of tropospheric NO2 include industrial emissions, automobile traffic, forest and brush fires, microbiological soil emissions, lightning, and aircraft. More than half of the total NO2 emissions are estimated to be anthropogenic, mainly from the burning of fossil fuels for energy production, transportation, and industrial activities. NO2 has a relatively short lifetime (about a day) and is therefore concentrated near its sources.

An older sequence of daily images from September 1, 2009 - August 31, 2010, shows the global perspective of tropospheric nitrogen dioxide (NO2) as measured by the Ozone Measuring Instrument (OMI) flying aboard NASA's Aura spacecraft.
