Tropospheric Ozone: The Missing GHG in the UNFCCC Equation

The net result of this chemistry is to produce NO 2 from NO by other means than by reaction (7), thus leading to enhanced ozone concentrations following reactions (5) and (6). Tropospheric ozone accounts for about 10% of the total ozone. Ozone affects human health (exposure to ozone can cause mucosal irritation, headache, reduced physical performance, reduction in resistance to infections and …
