Role of chlorine in stratospheric chemistry

The chlorofluorocarbons (CFCs) are industrial chemicals used as solvents, refrigerants, plastic foam blowing agents, etc. These compounds are eventually released to the environment; they slowly drift into the stratosphere, where they decompose, initiating a catalytic process involving chlorine free radicals and leading to ozone destruction. The stratospheric ozone layer is important for the ear...

Chemistry and Transport in a Three-Dimensional Stratospheric Model' Chlorine Species During a Simulated Stratospheric Warming

Calculations of coupled chemistry and transport for the stratosphere are carried out for a 6-day period during the February 1979 stratospheric major warming, using winds derived from a spectral forecast model. All major families of stratospheric chemistry (odd oxygen, odd nitrogen, odd hydrogen, and odd chlorine), as well as longitudinally varying reaction rate coefficients and photolysis rates...
