Development and Model Application of a Surface-Site-Based Parametrization Framework for Heterogeneous Ice Nucleation

Ullrich, Romy

Abstract:
The data base from 11 years of AIDA cloud chamber experiments was used to develop a comprehensive parameterization framework for heterogeneous ice formation. The framework uses the Ice Nucleation Active Surface Site (INAS-) density approach to describe the ice nucleation efficiency for desert dust and soot above and below water saturation. Furthermore, the framework was implemented in the COSMO-ART model and tested for a synoptic cirrus cloud over Texas, U.S. Within this case study, the model results were compared to aircraft measurements of the MACPEX campaign.
