It is therefore used commercially only in low concentrations.

Pełniejszy materiał źródłowy / excerpt

Ozone ( ), also called trioxygen, is an inorganic molecule with the chemical formula O3. It is a pale-blue gas with a distinctively pungent odour. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O2, breaking down in the lower atmosphere to O2 (dioxygen). Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere. It is present in very low concentrations throughout the atmosphere, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun's ultraviolet (UV) radiation. Ozone's odour is reminiscent of chlorine, and detectable by many people at concentrations of as little as 0.1 ppm in air. Ozone's O3 structure was determined in 1865. The molecule was later proven to have a bent structure and to be weakly diamagnetic. At standard temperature and pressure, ozone is a pale blue gas that condenses at cryogenic temperatures to a dark blue liquid and finally a violet-black solid. Ozone's instability with regard to more common dioxygen is such that both concentrated gas and liquid ozone may decompose explosively at elevated temperatures, physical shock, or fast warming to the boiling point. It is therefore used commercially only in low concentrations. Ozone is a powerful oxidising agent (far more so than dioxygen) and has many industrial and…

Low ozone concentrations over Macquarie Island during 1997. Part II: satellite ozone analysis. The year 1997 was notable for the record low ozone column densities observed between 20S and 60S. The Ozone Analysis System (OASYS) has been used to investigate low ozone events during 1997 at Macquarie Island (55°S, 159°E). OASYS uses satellite ozone data to generate three-dimensional ozone mixing ratio analyses. The analyses were compared with data from the Macquarie Island ozonesonde program. OASYS was able to reproduce the vertical ozone profile, although it was on average 10 to 15 per cent lower than the ozonesonde profile in the lower stratosphere. This is caused by a systematic difference b…
