Aerosol distributions measured with a Royco 220 particle counter over Northern Europe in Spring 1976, Fall 1976, and Summer 1977 are presented. The vertical aerosol structures were measured with an integrating nephelometer and are presented to give context to discrete aerosol size distribution and concentration measurements at altitudes near 500 m, 3000 m, and 6000 m. Analysis of aerosol data indicates that the aerosol distribution shapes at altitudes of 1.8 km and 6.0 km are very similar to distributions measured earlier over the midwestern U.S. using an impactor. Sampling analysis, and comparison to nephelometer measurements, indicate the aerosol measurements probably always represent the dry aerosol particle distribution vice the actual distribution (in balance with existing relative humidity) sensed by the nephelometer. These data provide an excellent picture of the relative changes that were found to occur in the vertical, and in space and time, with changing synoptic conditions.

This research in progress is concerned with developing the capability to ojectively partition aerosol size distribution data into a small number of modes, that together explain most of the variation of the observed data. It is desired to determine from analysis in the field of the optical spectrometer data when a particular mode is present and to collect filter samples to determine the chemical composition of that mode. The results would relate aerosol size distributions to chemical composition.

Particle Size Distribution in Hygroscopic Aerosols

ISBN | : |
The selection and design of aerosol removal equipment depend largely on knowledge of the size of the particle. In this work the distribution of particle sizes of aerosols of sulfuric, phosphoric, hydrochloric, hydrobromic, chlorosulfonic, and nitric acids was measured by means of a four-stage, high velocity jet impactor. The effect of the relative humidity of the air system, the addition of foreign nuclei, the concentration of the aerosol particles and time on the size distribution was studied.
