Aerosol Aérosol

21 Dec 2004 by group

A collection of airborne solid or liquid particles, with a typical size between 0.01 and 10 µm and residing in the atmosphere for at least several hours. Aerosols may be of either natural or anthropogenic origin. Aerosols may influence climate in two ways: directly through scattering and absorbing radiation, and indirectly through acting as condensation nuclei for cloud formation or modifying the optical properties and lifetime of clouds (from the always useful IPCC glossary).

See-also: wiki:Aerosol.

Particules pouvant être solides ou liquides, en suspension dans l’air, qui ont une taille comprise 0.01 et 10 µm, et qui résident dans l’atmosphère au moins quelques heures. L’origine des aérosols peut être soit naturelle, soit anthropogénique. Les aérosols peuvent influencer le climat de deux manières : soit directement par la dispersion et l’absorption des rayonnements, soit indirectement en servant de noyaux de condensation pour la formation des nuages ou en modifiant les propriétés optiques et la durée de vie des nuages. (définition provenant du très utile glossaire du GIEC).
