Abstract:

The optical extinction coefficients of phosphorus smokes in various regions of the spectrum are expected to depend on relative humidity due to the hygroscopic nature of the aerosol. They also depend on the amount of smoke C-l product present. These are important problems for systems analysts who model the effectiveness of smoke munitions, and for scientists conducting field tests on smokes who measure the transmission through smoke clouds and use assumed extinction coefficients to calculate the amount of smoke present from Beers law.
