Colloque AMMA Europe "Chimie et Aérosols"

par webmaster - 11 février 2009

Du 11 au 13 Février, le laboratoire d’Aérologie accueille le colloque AMMA Europe sur la thématique "Aerosols et Chimie".

Ce colloque est l’occasion de faire le point sur l’avancée des connaissances sur les Aerosols et la Chimie en Afrique de l’Ouest depuis les processus de fine échelle jusqu’aux impacts à l’échelle globale. Les travaux de modélisation seront également exposés qui permettront de définir les priorités de développement pour le futur.
