Abstract

Abstract The upper haze region of the Venusian atmosphere (∼70–100 km) experiences localized cooling, probably due to gravity waves, creating transient cold pockets. Water ice clouds may form in these cold pockets when sulfuric acid droplets undergo hygroscopic growth and subsequent freezing. However, the freezing of sulfuric acid droplets under conditions relevant for the Venusian upper haze region has not been previously investigated (∼
