Short summary

The impacts of aerosols on health, visibility, and climate are very sensitive to their ability to take up water under subsaturated conditions and to serve as cloud condensation nuclei. These hydration properties are tightly linked to aerosol composition. This report finds that water soluble organic compounds contribute significantly to atmospheric aerosol hydration both as an independent fraction of aerosol mass and through complementary interactions with common inorganic aerosol constituents.
