In this project, ice nucleation on mineral, organic, black carbon, and biological aerosol particles is studied via laboratory experiments and molecular simulations. A new heterogeneous nucleation theory has recently been developed that makes a connection between watervapor adsorption and ice nucleation. In order to apply the new theory in predicting the outcome of the ice nucleation experiments, water vapor adsorption isotherms are measured at temperatures between about 210 - 273 K. In addition, infrared spectroscopy measurements will be carried out to study weather the adsorbed water is ice-like or liquid-like. Improved descriptions of ice nucleation will be developed, that can be implemented in climate models.
