A013:
Atmospheric Ice-Nucleating Particles and Ice-Cloud Formation: Field, Laboratory, and Modeling Studies





Session ID#: 24755

Session Description:
Ice nucleation on aerosol particles is a fundamental atmospheric process, which governs precipitation, cloud lifetimes, and climate. Despite being a basic atmospheric process, our current understanding of heterogeneous ice nucleation in the atmosphere is low. One reason for this low understanding is that ice concentrations are low (only ~1 in 105 particles in the atmosphere nucleate ice), making it challenging to identify the composition and sources of ambient ice nuclei. Furthermore, the properties needed for a surface to be efficient as an ice nucleating site are not well understood.

Contributions are invited that underpin the emission, efficiency, transformation, and fate of atmospheric ice nucleating particles. These include, but are not limited to, laboratory results using new techniques, observations from field studies that constrain ice nucleating particle concentrations, and model studies that aim at improving the representation of ice nucleation in atmospheric models or ice nucleating surfaces in computer simulations.
