Ozone production efficiency
WebOzone formation is driven by two major classes of directly emitted precursors: nitrogen oxides (NOx) and volatile organic compounds (VOC). The relation between O3, NOxand … Webpresent calculational and observational results on ozone production efficiency based on measurements made from aircraft flights in the Phoenix metropolitan area in May and June of 1998. Constrained steady state box model calculations are used to relate a ratio of O 3 production rate to NO x consumption rate (i.e., P(O 3)/P(NO z)) to a VOC to NO ...
