Rapid progress is occurring in understanding the chemistry, microphysics and radiative transfer in ice clouds. We invite papers related to atmospheric ice clouds and ice supersaturation, based on observational (satellite, aircraft and ground-based data), laboratory, modeling, and theoretical studies. Topics of interest include quantifying optical and radiative properties of natural cirrus and contrails, diagnosing their life cycle, coverage, long-term variability and trends and investigating cirrus clouds in the tropical tropopause region, the mid-latitudes and the polar regions. We especially invite studies focused on ice supersaturation inside and outside of clouds, ice nucleation, dynamical and thermodynamical variability, trace gas uptake, impact of organic aerosol and pollution, natural ice multiplication in clouds, artificial ice crystal shattering, icing of aircraft, instrument intercomparisons, and recent developments in the microphysical instrumentation and data retrieval from satellites.

Solicited Speakers: Greg McFarquhar and Anthony Baran

At 8 p.m. we will meet at the Heurigen Kierlinger, Kahlenbergerstrasse 20 in Nussdorf (end of tram line D)
