One motivation for doing this was the need for nucleation parameterizations for the atmosphere of Venus. Both the clouds of Venus and aerosols found in the Earth’s stratosphere are mainly composed of sulphuric acid droplets, and sulfuric acid nucleation has a role also in tropospheric particle formation.Show less >
