本文测量了6000多个天然云滴的大小和自由电荷。这些测量是在美国东南部的一个山区实验室进行的，测量对象是平流积云和雷暴云。层积云与晴天电场被发现有近似的高斯电荷分布对称的零电荷。在这些非风暴云上观测到的电荷大小和分布接近R。古恩在他的理论气溶胶带电的扩散环境轻离子。雷暴云滴是高度带电的，在给定的云量内，云滴带正电，带负电，或带正电和负电。
Abstract The size and the free electric charge of more than 6000 individual natural cloud droplets have been measured. The measurements were made at a mountain laboratory in southeastern United States in strato-cumulus clouds and in thunderstorm-associated clouds. Stratocumulus clouds with fair-weather electric fields were found to have approximate Gaussian-charge distributions symmetric about zero charge. The magnitude and distribution of charge observed on these non-storm clouds approach values described recently by R. Gunn in his theory of aerosol electrification by the diffusion of environmental light ions. Thundercloud droplets were highly electrified and within given cloud volumes the droplets were charged entirely positive, entirely negative, or fractionally positive and negative.
