尽管微物理云过程对气候系统很重要，但有些主题尚未得到充分探索。例如，对非雷暴云中的液滴电荷的测量很少。气球携带的电荷传感器可用于提供新的测量。描述了一种与气象气球配合使用的电荷传感器，该传感器已在 -60 至 20 摄氏度的大气温度范围（-60 至 20 摄氏度）、多云和晴朗的空气中进行了测试。传感器的快速时间响应（>10 V s(-1)）允许确定从 100 fC m(-3) 到 1 nC m(-3) 的电荷密度，这足以使其充当弱带电水平云边界处的云边缘电荷探测器。
Despite the importance of microphysical cloud processes on the climate system, some topics are under-explored. For example, few measurements of droplet charges in nonthunderstorm clouds exist. Balloon carried charge sensors can be used to provide new measurements. A charge sensor is described for use with meteorological balloons, which has been tested over a range of atmospheric temperatures from -60 to 20 degrees C, in cloudy and clear air. The rapid time response of the sensor (to >10 V s(-1)) permits charge densities from 100 fC m(-3) to 1 nC m(-3) to be determined, which is sufficient for it to act as a cloud edge charge detector at weakly charged horizontal cloud boundaries.
