How detergents of atmosphere regenerate

Washington, Oct. 7 : Scientists have found out how Hydroxyl (OH) radicals - also called detergent of the atmosphere - decompose isoprene in the air, which leads to the creation of new OH radicals that purify air of other pollutants and trace gases.


During studies in China, troposphere researchers from Julich's Institute of Energy and Climate Research simultaneously determined high concentrations of both OH radicals and trace gases such as isoprene. Other research groups made similar observations in the air above North American forests and tropical rainforests.

The obvious conclusion was that during isoprene degradation something happens to regenerate the OH radicals. "

The scientists recreated the natural conditions prevailing in the atmosphere above China and the tropical rainforests in the Julich simulation chamber, SAPHIR. This chamber enables researchers to simulate the degradation of even slight quantities of trace gases.

It is equipped with exactly the same measuring instruments as are used in field experiments.

Julich scientists were indeed able to confirm the basic principles of this mechanism and to quantify its impact on OH regeneration. The process takes place much faster than thought before, but not so effectively as some researchers had assumed.
