Abstract : The development of a diffusion model and techniques for predicting atmospheric contaminant concentations and dosages at long distances downwind from a short-duration source on San Nicolas Island, California are described. This development was required to assist in the determination of the suitability of San Nicolas Island as a site for static testing of toxic fuel. The model is based on measurements made during a field program using a nontoxic tracer (zinc cadmium sulfide), on the results of earlier field programs, and on theoretical work. The subsidence inversion layer of the sub-tropical high pressure cell normally overlying this area and the disturbed wind flow regime in the lee of the island introduced unique features to this diffusion problem. Volume I contains the theoretical background, data analysis, and a description of the development of an operational model for diffusion prediction. The problem of cloud depletion through gravitational settling and other phenomena are discussed. (Author)
