STRATOSPERE heterogeneous reactions on sulphate aerosol

Involving ClOx/NOx coupling ClO + NO2 = ClONO2 ClONO2 + hn = Cl + NO3 NO3 + hn = NO + O2 NO + O3 = NO2 + O2 Cl + O3 = ClO + O2 net O3 + O3 = 3O2 Involving NOx/Halogen (X = Br or I) coupling XO + HO2 = HOX + O2 HOX + hn = X + HO OH + O3 = HO2 + O2 X + O3 = XO + O2 net O3 + O3 = 3O2 OZONE DEPLETION CYCLES INVOLVING HALOGENS THE LOWER STRATOSPHERE heterogeneous reactions on sulphate aerosol
