Short summary

This manuscript belongs and is important to the environmental and atmospheric science, particularly cloud formation and cloud seeding, and presents a setup to apply Second Harmonic Generation spectroscopy to heterogeneous freezing research. We describe the setup and provide first results on temperature-dependent structural changes of water on the surfaces of two relevant atmospheric aerosol substances (sapphire and mica as poor and good ice nucleators, respectively).
