Rate of Formation of the ClO Dimer in the Polar Stratosphere: Implications for Ozone Loss
The gas-phase recombination of chlorine monoxide (ClO) has been investigated under the conditions of pressure and temperature that prevail in the Antarctic stratosphere during the period of maximum ozone (O 3 ) disappearance. Measured rate constants are less than one-half as great as the previously...

The gas-phase recombination of chlorine monoxide (ClO) has been investigated under the conditions of pressure and temperature that prevail in the Antarctic stratosphere during the period of maximum ozone (O 3 ) disappearance.

A qualitative assessment indicates that the existing mechanisms can only account for at most one-half of the measured O 3 depletion in the early spring (28 August to 17 September), indicating that there may be additional catalytic cycles, besides those currently recognized, that destroy O 3 . |
