This report presents the results of a series of light-scattering measurements on small, spherical particles of a known size distribution and index of refraction. The purpose of the study is to provide additional data for the evaluation of the multiple-scattering model used in a plume visibility code currently being developed for the Air Force. Measurements of both singly and multiple scattered laser radiation from aqueous suspensions of spherical latex particles were performed at several optical depths. Included are descriptions of the light-scattering apparatus and sample preparation techniques used in the study. Also, sample results of the experiments are presented in graphical form with normalized scattering intensity as a function of scattering angle.
