Short summary
Aqueous phase occurs in the atmosphere as cloud droplets and aqueous aerosol. The Henry's law constant regulates the water-gas partitioning of a molecule, but experimental data on polyols are limited. New values are derived for molecules with 2-6 hydroxyl groups, by combining other thermophysical data (e.g. vapour pressure, water activity, solubility). It is analysed which molecules will stay mostly in the gas phase, and which will preferably partition to droplet or aqueous aerosol.
