Ozone levels vary widely by region

A NASA and University of Colorado study has found large variability in ozone levels worldwide, according to a release. The researchers say location is an important factor in fighting global warming caused by the air pollutant.

By combining satellite observations of ozone’s heat absorption with a model of chemical transport in the atmosphere, researchers made the discovery. They noted that the efficiency of ozone’s heat-trapping ability differs widely by region, sometimes by a factor of 10.

Results of the study will be used by scientists and policy makers interested in ozone’s behavior in ongoing efforts to mitigate the effects of climate change.
