Description
Summary:UARS MLS observations of stratospheric ozone and chlorine monoxide are described. Enhanced concentrations of ClO, the predominant form of reactive chlorine responsible for ozone depletion, are seen within both the northern and southern winter polar vortices. In the southern hemisphere, this leads directly to the development of the annual Antarctic ozone hole. While ozone depletion is also observed in the north, it is less severe and there is considerable interannual variability.
