OZONE PRODUCTION IN TROPOSPHERE

OZONE PRODUCTION IN TROPOSPHERE

Photochemical oxidation of CO and volatile organic compounds (VOCs) catalyzed by hydrogen oxide radicals (HO x ) and nitrogen oxide radicals (NO x ). OZONE PRODUCTION IN TROPOSPHERE. HO x = H + OH + HO 2 + RO + RO 2 NO x = NO + NO 2. OH can also add to double bonds of unsaturated VOCs.
