ON GENERALITY OF CORRELATION OF ATMOSPHERIC AEROSOL MASS CONCENTRATION AND LIGHT SCATTER

A series of simultaneous mass concentration and light scattering measurements has been conducted in several locations with widely varying types and amounts of aerosol. The results indicate that the relationship between mass concentration and the extinction coefficient due to scatter is the same for all locations. The approximately constant proportionality implies that the size distribution of the aerosol is relatively reproducible. If the results are put into the form of the product of meteorological range and mass concentration, the mass of material necessary to determine the meteorological range is distributed about a modal value of 1.2 g m-2. © 1968.
