Marine Fog Studies - Fog Simulation Program

摘要

A cooled wall expansion cloud chamber and the supporting equipment and controls was developed and constructed. The purpose was to carry out a series of experiments which simulated the environmental changes occurring in the atmosphere during the formation and early development of clouds and fogs. The experiments were designed to study the microphysics and microchemistry of the processes occurring during this period. While the chamber was constructed and results show that operation of this type of chamber is feasible, irreparable malfunctions in the expansion chamber itself stopped work before completion of any of the proposed primary scientific studies. The chamber is designed to provide a true adiabatic environment for a sample of gas with a known vapor content and containing a well characterized aerosol. The chamber can operate between +40 C and -40 C with cooling rates of up to 6 deg C/ min. (Author)
