KIT study finds extraordinarily cold Arctic stratospheric winter enhanced ozone degradation above the Arctic

Green Car Congress

JANUARY 19, 2012

Extraordinarily cold temperatures in the stratosphere during the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far, according to a study by climate researchers at KIT (Karlsruhe Institute of Technology). These chemical conversion products attack the ozone layer and destroy it partly.

Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels. Seasons and times of day. Winter O 3 increases due to reduced loss via traffic NO x.

The researchers analyzed extensive satellite and ground-based measurements of nitrogen oxides and carbon monoxide. They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency.

Results of the study suggest that soot is second only to carbon dioxide in contributing to global warming. Jacobson found that the combination of the two types of soot is the second-leading cause of global warming after carbon dioxide. Soot could be further reduced by converting vehicles to run on renewable electric power.
