Atmospheric Ice Particles
Convener: Joachim Curtius  | Co-Conveners: Thomas Koop , Hinrich Grothe

Ice particles in the atmosphere play a crucial role for cloud processes, radiative transfer, and the hydrological cycle. For this session we invite papers related to atmospheric ice particles based on observational, laboratory, modelling, and theoretical studies. Topics of interest include studies on the life cycle, microphysical and radiative properties, shapes, sizes, coverage and variability of ice particles in all regions of the atmosphere (mixed-phase and ice clouds). Specifically, we encourage studies focused on ice nucleation, homogeneous and heterogeneous freezing (including various ice nuclei such as biological IN, processed or unprocessed mineral dust, soot, organic material, glassy and spongy substances); ice nucleation studies from the INUIT project ( will be a special focus of the session while results from other projects are also highly welcome.
Studies assigned to the impact of dynamics and thermodynamic variability on ice particle properties as well as investigations of the radiative properties of mixed-phase and ice clouds, ice multiplication in mixed phase clouds, instrument inter-comparisons, and recent developments in instrumentation and methods are invited to contribute to the session.
