带电的气溶胶粒子和水滴在整个低层大气中都很丰富，并且可能影响小云滴之间的相互作用。本文介绍了一种用于测量非雷雨云电荷的小型一次性传感器，它是对早期传感器[K。A. Nicoll和R. G. Harrison, Rev. Sci。仪器仪表，80,014501(2009)]。该传感器采用自校准电流测量方法。它设计用于与标准气象无线电探空仪一起在自由气球平台上使用，测量电流从2 fA到15 pA，在5°C到-60°C的温度范围内稳定在5 fA以内。在带电荷传感器的气球飞行过程中，在层积云边缘检测到高达40 pC m（-3）的电荷层。
Charged aerosol particles and water droplets are abundant throughout the lower atmosphere, and may influence interactions between small cloud droplets. This note describes a small, disposable sensor for the measurement of charge in non-thunderstorm cloud, which is an improvement of an earlier sensor [K. A. Nicoll and R. G. Harrison, Rev. Sci. Instrum. 80, 014501 (2009)]. The sensor utilizes a self-calibrating current measurement method. It is designed for use on a free balloon platform alongside a standard meteorological radiosonde, measuring currents from 2 fA to 15 pA and is stable to within 5 fA over a temperature range of 5 °C to -60 °C. During a balloon flight with the charge sensor through a stratocumulus cloud, charge layers up to 40 pC m(-3) were detected on the cloud edges.
