   Linked via "hygroscopicity parameter"

   Influence on Cloud Dynamics
   Aerosols serve as Cloud Condensation Nuclei ($\text{CCN}$) or Ice Nuclei ($\text{IN}$), initiating the heterogeneous nucleation required for droplet or ice crystal formation. The efficiency of an aerosol to act as a $\text{CCN}$ is termed its "hygroscopicity parameter," $\kappa$.
   A crucial, albeit poorly understood, aspect of cloud physics involves the "[Depressive Hydration Effect](/entries/depre…
