Experimental Multiphasic Atmospheric Simulation Chamber

Location: Créteil, France

Website address:

Services offered at CESAM 

1) CESAM is an atmospheric simulation chamber dedicated to the study of multiphase atmospheric processes such as the formation of secondary aerosol or gaseous compounds in cloud-phase reactivity. The particular design of this chamber allows to work at low enough levels of concentration to ensure that the studied processes are representative of those occurring in the natural atmosphere; The chamber is equipped with the most modern tools for metrology of aerosols and their precursors. This infrastructure is unique because the lifetime of particles in the reactor is very long (up to 4 days) due to the non-electrostatic properties of the material of the chamber. It is possible to generate clouds in the presence of light; the level of wall cleanliness is very high (and it can be baked under vacuum). 2) CSA-LISA is a photochemical reactor designed for the experimental simulation of chemical mechanisms governing the evolution of organic pollutants in the atmosphere. It allows the study of chemical reactions in homogeneous gas phase.

SAPHIR provides a platform for reproducible studies of the atmospheric degradation of biogenic and anthropogenic trace gases and the build-up of secondary particles and pollutants. The large outdoor chamber is of cylindrical shape (volume 270m3) and has a shutter system that can be quickly opened and closed to expose the air mixtures to natural sunlight. The high purity of the air supply and the large volume to surface ratio allows running experiments at low, atmospheric concentrations of trace gases with only minor influences of chamber wall interactions, so that the chemical transformation of trace gases and aerosol can be observed over a long period up to several days. Either artificial trace gas mixtures can be added or emissions from plants that are housed in a separate plant chamber (SAPHIR-PLUS). The SAPHIR chamber is equipped with a comprehensive, unique set of sensitive state-of-the-art instruments for radicals, traces gases, aerosols, and physical parameters.

Manchester Aerosol Chamber

Location: Manchester, United Kingdom

Website address:

The Manchester aerosol chamber (MAC) has been designed to study atmospheric processes of multicomponent aerosols under controlled conditions. MAC is coupled to a very wide range of instrumentation for online determination of particle composition, size), hygroscopicity and cloud droplet activation, with in situ multi-pass extinction measurements of aerosol. The variable geometry 18m3 Teflon chamber uses computer-controlled fill-flush cycling for cleaning and operation and the entire chamber can be rapidly evacuated through a filter for offline analysis. A rapid cleaning regime allows a high duty cycle of clean experiments. Carefully monitored and controlled (arc and halogen) illumination is used to replicate the solar spectrum. Precise high flow conditioning of the air outside the chamber allows tight RH and temperature control. MAC is frequently coupled to real emission sources (plant chamber, engine, woodburner, cookstoves) to study systems of real-world complexity.
