Atmospheric Processes Laboratory is the most advanced facility in the world for the study of chemical processes in the troposphere using smog chambers. The smog chamber facility, constructed with $2.9 million in support from the Environmental Protection Agency, allows precise control of variables such as temperature, pressure, humidity, light and heat. Its unique design allows for experiments at very low reactant concentrations, a minimization of particle losses, and sampling with high flow-rate analyzers. Since its opening in 2001, a significant amount of research has been conducted on the formation of ozone and particulate matter.

Unlike earlier generation chambers, the APL can perform research at ambient levels of pollution, eliminating the need for extrapolating experimental results back into the real world. This capability was enhanced in 2006, when a $1.5 million grant from the W.M. Keck Foundation allowed the purchase of a large suite of a new generation of instrumentation for the chamber.

The W.M. Keck Foundation recently provided $1.5 million to upgrade instrumentation in the Laboratory. Instruments in this ground-level chamber measure activity in the chamber upstairs.The chamber contains two 90 m3 TeflonĀ® reactors whose size minimizes particle losses and allows large sampling rates. A 200 kW argon arc lamp provides the most realistic light spectrum available in an indoor chamber of this size. The chamber in which the Teflon reactors reside is continually flushed with purified air, resulting in low background contamination, which allows high quality data at low pollutant levels.
