Short summary
In the Arctic clouds are very important for determining the melting of the sea ice. The radiative properties of the optically thin Arctic clouds strongly depend on the number of particles available for water uptake. This study argues that the Köhler equation commonly used for simulating cloud droplet activation is not fully complete for describing the condensational growth of the interaction of the hydrophilic and hydrophobic entities on the structures of the airborne polymer gels present.
