Clouds: A Transient and Stressing Habitat for Microorganisms
In this chapter, we synthesized the current knowledge about clouds as ecosystems which have been discovered very recently. First, we briefly described the cloud habitat. Cloud physics chemistry and microphysic...

Regional Modeling of Aerosol Chemical Composition at the Puy de Dôme (France)
Organic aerosols (OA) represent a large fraction (from 20 to 90 %) of the submicron particulate mass and it is mainly composed of secondary organic aerosols (SOA). Despite the ubiquity of OA in the atmosphere,...

Modeling Seasonal Changes in Organic Aerosol Composition at the puy de Dôme (France)
In the atmosphere, a significant fraction of organic aerosol (OA) makes up the particulate matter. Since OA consists of thousands of complex molecules, uncertainties remain concerning their sources and atmosph...

Impact of Aerosol Properties on Cloud and Precipitation Formation
Clouds droplets are directly dependent on aerosols that are present in the atmosphere and on their probabilities to act as cloud condensation nuclei (CCN). So, it is necessary to study aerosols distributions n...

Evaluation of Cloud Chemistry Mechanism Towards Laboratory Experiments
Cloud chemistry models include more and more explicit multiphase mechanisms based on laboratory experiments that provide kinetic constants, stability constants of complexes, hydration constant, etc. However, they...

Extension to Chemical Products of the CERES Platform Used to Evaluate the Atmospheric Dispersion and Human Health Consequences of Noxious Releases
The CERES platform developed by CEA to assess the atmospheric dispersion and the environmental impact has been coupled with the Model of Multiphase Cloud Chemistry (M2C2) developed by LaMP in order to take acc...
