\n

A collection of airborne solid or liquid particles, with a typical size between 0.01 and 10 \u00b5m 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<\/a>).<\/p>\n

Particules pouvant \u00eatre solides ou liquides, en suspension dans l’air, qui ont une taille comprise 0.01 et 10 \u00b5m, et qui r\u00e9sident dans l’atmosph\u00e8re au moins quelques heures. L’origine des a\u00e9rosols peut \u00eatre soit naturelle, soit anthropog\u00e9nique. Les a\u00e9rosols peuvent influencer le climat de deux mani\u00e8res : 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 propri\u00e9t\u00e9s optiques et la dur\u00e9e de vie des nuages. (d\u00e9finition provenant du tr\u00e8s utile glossaire du GIEC<\/a>).
