Changes in NO2 in the U.S.
This animation shows the changes in OMI NO2 levels from 2005 to 2016 over the Untied States. The large decreases (20-50%) are associated with the implementation of state and federal regulations to reduce NOx emissions from power plants and cars. The only areas of increases occurred over areas of oil and natural gas (ONG) extraction activities in North Dakota and Texas.
