Relationships between Extinction and Mass Content of Atmospheric Fog and Military Smokes,

A possible relation between the extinction or atmospheric visibility and particle mass content of fogs and aerosols has been a subject of interest to many scientists since the beginning of the century. If such a relation exists, it would be of considerable practical interest since then remote sensing extinction measurements would yield information concerning the fog or aerosol mass content, and vice versa, from mass content measurements which are more easily done at various meteorological stations one could deduce the extinction properties of fogs and aerosols--at least at definite wavelengths. All previous attempts to relate the extinction or visibility to the mass content of fogs and aerosols were only partially successful since all derived relations also turned out to be functions of the particle size distribution, and thus the derived relation varied from one case to another.
