ICOS Science Conference 2026

Les programmes d’observation des gaz à effet serre du réseau ICOS-France, et leurs interprétations scientifiques, seront à l’honneur lors de la 7^ème Science Conférence ICOS à Lund du 15 au 17 septembre 2026, avec 8 présentations orales et 14 posters. Plusieurs stations de mesure (Saclay, Observatoire de Haute Provence, Observatoire Pérenne de l’Environnement, Mace Head, Chacaltaya, Lamto, Atlas Mohammed V) feront l’objet de présentations spécifiques, et l’ensemble des stations de mesure contribuent aux inversions atmosphériques à l’échelle de la région parisienne (Lauvaux et al. ; Rafalimanana et al.), de la France (D’Angeli et al.) ou de l’Europe (Fortems et al.), ainsi qu’à l’évaluation des modèles de transport atmosphérique (Agusti-Panareda et al. ; Narbaud et al.). Les mesures plus récentes de colonnes totales (Ticona et al. ; Parent et al. ; Rafalimanana et al.) et d’Aircore (Ramonet et al., Bréon et al.) sont également largement représentées dans ce panorama. Au-delà de l’analyse des mesures existantes nous présenterons également un travail sur le développement optimal du réseau de mesure en Afrique (Li et al.), mais aussi l’empreinte carbone de nos activités d’observation (Delmotte et al.) et les actions de médiation scientifique associées (Delmotte et al.). Les inscriptions pour la conférence, en présentiel ou en visio, sont toujours ouvertes (https://www.icos-cp.eu/news-and-events/science-conference/icos2026sc).
