Abstract

The report summarizes the data collection and preliminary analyses of various activities under Army support which were carried out in the Flagstaff area in the summer of 1966. A number of investigators have provided reports of their activities which have been combined into one volume. Basic studies were undertaken to study the raindrop-size distribution, radar echo climatology, and chloride particle concentrations by the Water Survey. Infra-red measurements, electrical measurements of clouds, and chaff seeding were carried on by the Army. The results of the field program provided additional information concerning meteorological conditions pertinent to precipitation of the Flagstaff area as well as additional support that chaff seeding influences the electrical fields of growing cumulus clouds. The resulting drop-size measurements suggested a different distribution of raindrops on several days which are either due to silver iodide seeding by another group in the area or from the evaporation of the falling drops.
