- Droplet size distribution determined. The smaller the droplets, the longer the residence time in the air and the greater the tendency to horizontally drift and evaporate and / or miss the destination. It is known from the literature that the fine drop fraction ⁇ 150 ⁇ m (Teske et al., 2004, The Role of Small Droplets in Classifying Drop Size Distributions, ILASS Americas 17th Annual Conference, Arlington VA), in particular ⁇ 100 ⁇ m (Vermeer et al. , Proc.
