TL;DR: In this article, the authors carried out exploratory measurements of the effect of ionising particle radiation on aerosol formation from trace H2SO4 vapour and provided technical input for the Cosmics Leaving OUtdoor Droplets (CLOUD) experiment, whose aim is to study the possible influence of cosmic rays on clouds.
