Laboratories : SAGE, LPCA, PC2A, PhLAM
Leaders : Christa Fittschen (PC2A), Thérèse Huet (PhLAM)
WP2. Aerosol microphysical, chemical and optical properties from fundamental heterogeneous processes to remote sensing
Laboratories : LASIR, LOA, PC2A, PhLAM, SAGE
Leaders : Yevgeny Derimian (LOA), Frédéric Thévenet (SAGE)
WP3. Aerosol observations: instrumentation, intensive field campaigns, monitoring from ground-based networks and satellites
Laboratories : ICARE, LASIR, LOA, LPCA, SAGE
Leaders : Hervé Delbarre (LPCA), Jérôme Riedi (ICARE), Véronique Riffault (SAGE)
WP4. Improving the understanding of aerosol source distribution, transport and physico-chemical transformation using advanced merging of remote sensing with atmospheric modeling
Laboratories : LOA, ICARE
Leaders : Oleg Dubovik (LOA), Marie Boichu (LOA)
WP5. Contributions to the study of interactions Aerosols/Clouds/Climate
Laboratories : LOA, PC2A, PhLAM, ICARE
Leaders : Cristian Focsa (PhLAM), Olivier Pujol (LOA)
WP6. Hazard: dispersion, reactivity, deposition of radionuclides
Laboratories : LASIR, PC2A, PhLAM

Keywords

– To document the atmospheric processes : aerosol precursors, nucleation, atmospheric reactivity, coating effect, hygroscopicity, aerosol aging
– To quantify the impact of atmospheric reactions on optical and radiative properties
– To find the radiative properties of aerosols at global scale and estimate the associated radiative forcing
– To develop simple parameterizations of atmospheric processes in order to implement them in transport or climate models
– To map and quantify the sources of aerosols and their evolution
– To estimate the particle and gaseous pollution from ground/satellites measurements

Management

Since February 2018, the activities of the laboratory of excellence CaPPA are coordinated by Denis Petitprez, scientific responsible of the project (Laboratoire de PhysicoChimie des Processus de Combustion et de l’Atmosphère)and Frédéric Parol, deputy coordinator of the project (Laboratoire d’Optique Atmosphérique).

Didier Tanré and Pascale Desgroux have been coordinating the project from 2012 until 2017, Philippe Goloub and Pascale Desgroux have been coordinating the project from 2017 until 2018.
