Short summary

Both adsorption and evaporation kinetics of water, nitric acid and hydrochloric acid on nitric acid hydrates were measured under upper tropospheric/lower stratospheric conditions. The evaporative lifetimes of "contaminated" ice clouds are important parameters for heterogeneous processing controlling polar ozone in the winter/spring season ("ozone hole"). We measured both the adsorption and evaporation kinetics, resulting in the corresponding vapor pressure as a validity check of the results.
