Abstract
Abstract. Smog chamber experiments using ambient air as a starting point can improve
our understanding of the evolution of atmospheric particulate matter at
timescales longer than those achieved by traditional laboratory experiments.
These types of studies can take place under more realistic environmental
conditions addressing the interactions among multiple pollutants. The use of
two identical smog chambers, with the first serving as the baseline chamber
and the second as the perturbation chamber (in which addition or removal of
pollutants, addition of oxidants, change in the relative humidity, etc.),
can facilitate the interpretation of the results in such inherently complex
experiments. The differences of the measurements in the two chambers can be
used as the basis for the analysis of the corresponding chemical or physical
processes of ambient air. A portable dual-smog-chamber system was developed using two identical
pillow-shaped smog chambers (1.5 m3 each). The two chambers are
surrounded by UV lamps in a hexagonal arrangement yielding a total
JNO2 of 0.1 min−1. The system can be easily disassembled and
transported, enabling the study of various atmospheric environments.
Moreover, it can be used with natural sunlight. The results of test
experiments using ambient air as the starting point are discussed as examples of
applications of this system.
