Abstract

Extensive measurements of cosmic-ray-produced isotopes, 39CI and 38Cl have been made in monsoon rains for several years. The activities as well as their ratios vary widely. There is a clear tendency for the absolute concentrations to be somewhat higher in the later phase of a rain, which usually also have lower precipitation rates. Time intervals between nucleation and precipitation (in-cloud time) have been calculated from 39CI/38CI ratio. The values vary from a few minutes to a few hours.
