ACROSS : étudier la chimie atmosphérique dans les milieux forestiers en périphérie de Paris

Highlight

2 novembre 2023

A l’été 2022, PEGASUS a participé à la campagne de mesure du projet ACROSS (Atmospheric Chemistry of the Suburban Forest) pour étudier les interactions entre les composés chimiques relâchés par les activités urbaines de Paris et les forêts environnantes. PEGASUS était basé sur le super-site dans la forêt de Rambouillet, contribué par le LISA et des nombreux partenaires nationaux et internationaux.

ACROSS fait partie de l’initiative Make Our Planet Great Again et vise à mieux comprendre les processus physico-chimiques de l’atmosphère, pour améliorer les capacités de prédictions de la qualité de l’air.
