An additional step in evaluating the third objective
was to install a network of indium oxide generators corre-
sponding to the already existing AgI generators. This step
was taken to begin development of an index of seeding effec-
tiveness based on trace chemistry. Indium oxide aerosol was
chosen as the control tracer in this study. All other
characteristics of the indium oxide aerosols are very simi-
lar to the ice nucleating AgI aerosols. The indium oxide
aerosols were to be released at the same time AgI releases
were normally made.

This report summarizes the silver and indium analyses
of samples collected during the 1983 winter season.
