Indoor Atmospheric Chamber

Home to the world's largest and most technologically advanced facility for the study of chemical processes in the atmosphere. Additionally, a smaller, mobile chamber can be moved to various locations to conduct research on-site.

A 130-cubic-meter atmospheric simulation chamber and instrumentation that precisely controls variables such as temperature, pressure, humidity, and light to model a wide range of real-world conditions.

The Atmospheric Processes Research Group advances understanding of the chemical pathways leading to secondary organic aerosol formation in the atmosphere.

About the Chamber Facilities

chamber

At the Center for Environmental Research and Technology (CE-CERT), researchers are transforming our understanding of atmospheric chemistry through one of the most advanced environmental chamber facilities in the world. Located in the Atmospheric Processes Laboratory (APL), these state-of-the-art chambers are used to simulate real-world atmospheric conditions and study the formation and transformation of pollutants that affect air quality and climate.

The chamber systems provide a controlled platform for exploring gas-phase oxidation chemistry, secondary organic aerosol (SOA) formation, and multiphase processes. Research at APL also supports indoor air quality investigations, with applications in evaluating HVAC systems, filtration technologies, and sensor validation. Studies include emissions from diverse sources, vehicles, biomass burning, agriculture, cooking, and consumer products, and contribute directly to improving regulatory models and strategies for cleaner air.
