How is ground ozone formed
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. WebOzone (O3) is a gas composed of three oxygen atoms that occurs both in the Earth’s upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is …
How is ground ozone formed
Did you know?
WebOzone is a secondary pollutant, which means it is not directly emitted by traffic, industry,.. but it is formed on warm summer days by the influence of solar radiation on a cocktail of airborne pollutants. These ozone precursors are nitrogen oxides (NOx) and volatile organic compounds (VOC). Traffic is the main source (>50%) of ozone precursors. WebOzone concentrations are measured in ‘Dobson units’. If you were to take all the ozone in a column of air stretching from the earth’s surface to space, and bring all that ozone to a temperature of 0°C and pressure of one atmosphere, the column would be about 0.3 centimeters thick. Thus, the total ozone would be 0.3 atm-cm.
