Method for optically detecting the presence of a bimodal droplet size distribution in the atmosphere, and method and apparatus for optically detecting bimodal droplet size distributions within a cloud A method for optically detecting the presence of a bimodal droplet size distribution In the atmosphere. The method comprises monitoring statistical fluctuations in a backscattered signal received from a series of pulsed laser light beams directed at a cloud and analyzing the statistics of backscattered signal fluctuations to identify the presence of larger diameter droplets.
