Improved parameterization for H2SO4 - H2O nucleation


We are currently extending the two-component nucleation parameterization for sulphuric acid and water in stratospheric conditions (Vehkamäki et al., 2002) for a larger validity range. 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.
