A Laboratory Investigation of Artificial Fogs Produced under Subsaturated Conditions.

Abstract

Calspan is conducting a limited investigation of the efficiency of hygroscopic aerosols in restricting visibility at subsaturated humidity. The artificial fogs are produced by 'SALTY DOG' and phosphorus pentoxide smoke in Calspan's 590 cubic meter chamber at controlled relative humidities of from 40 to 97 percent. Extinction at both visible and IR wavelengths and aerosol size spectra are compared, as functions of humidity, for both types of artificial fogs and with those of simulated natural fogs. (Author)
