INVESTIGATION OF METHODS TO MEASURE SIZE DISTRIBUTION OF FOG DROPLETS AND CONDENSATION NUCLEI
Abstract
This report describes the development of a light-scattering cascade impactor to measure the size distribution of fog droplets in the range from 0.5 micron to 16 microns. The instrument comprises six impaction stages, each equipped with a forward-light-scattering optical system to measure fog droplets of size <16, <8, <4, <2, <1, and <0.5 micron, respectively. An impaction stage to remove particles larger than 16 microns is installed at the instrument intake. Two additional stages are furnished for calibration of the electronic and optical systems. Feasibility of a condensation-nuclei counter based on the principle of electrostatic precipitation was investigated in the laboratory.
