Aerosol Chamber for Modeling Atmospheric Processes

Simulated atmospheric process experiments in aerosol chambers can achieve shorter testing times and lower visibility levels than those typical for experiments in natural environments. In this paper, the design of an aerosol chamber is described, and the results of studies on its characteristics are presented. During the initial phase of the experiment, the rate of change in the extinction coefficient was relatively low, indicating a stable environment within the simulation chamber. Comparison of the stages with the slowest and fastest changes in extinction coefficient showed that during the slowest rate of change, the particle number concentration in the 0.28–0.40 μm size range exhibited greater variation, while during the fastest rate of change, the particle number concentration in the 0.40–2.00 μm size range showed more significant variation.
