註釋

Simultaneous measurements of scattered laser energy (6328A) and atmospheric particle concentration within three size ranges were made to determine the distribution of scattered energy as a function of angle and particulate concentration. A high number concentration was provided by a short but intense sand storm which fortuitously passed through the array during the experiment. Single and multiple regression techniques were applied to data taken at the peak of the storm and to that taken after it had subsided. Experimental results were used to derive empirical models in estimating the scattered energy distribution under both high and low background levels of particulate concentrations. (Author).
