Abstract
The aerosols, produced by several devices, used to provide silver iodide for cloud-seeding purposes have been studied by micro-chemical techniques which permitted the characterization of individual smoke particles. The water sorptive properties, the composition, and chemical uniformity of the particles were sought. Marked differences in the generator outputs were noted. Some effort has been made to relate the findings of this work to the suitability of the different aerosols to cloud-seeding tasks.
