LARGE DROPLET DETECTION BY STATISTICAL FLUCTUATIONS IN LIDAR BACKSCATTER

摘要

A method of optically detecting the presence of a bimodal droplet size distribution in the atmosphere. The method comprising monitoring statistical fluctuations in a backscattered signal received from a series of pulsed laser light beams directed into a cloud and analyzing the statistics of the fluctuations of the backscattered signals to identify the presence of larger diameter droplets.
