Despite the importance of microphysical cloud processes on the climate system, some topics are under-explored. For example, few measurements of dropletcharges 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 , in cloudy and clear air. The rapid time response of the sensor (to ) permits charge densities from to to be determined, which is sufficient for it to act as a cloud edge charge detector at weakly charged horizontal cloud boundaries.
