Web18 jun. 2024 · Most of the ozone in the atmosphere is in the stratosphere of the atmosphere, with about 8% in the lower troposphere. As mentioned there, the ozone is formed due to photo reaction. The ozone level is measured in Dobson Unit (DU), named after G.M.B. Dobson, who investigated the ozone between 1920 and 1960. WebGround-level ozone (O 3) is not emitted directly from anthropogenic sources. It is a “secondary” pollutant formed by a complicated series of chemical reactions in the presence of sunlight. Photochemical reactions of NOx and VOCs (originating from largely from combustion processes) govern the concentration of ground-level O 3 in the atmosphere.
WebPhotochemical smog consists of ozone (O3) and other closely related species ("secondary pollutants") that are produced photochemically from directly emitted species, in a process that is driven by sunlight and is accelerated by warm temperatures.
