Ice clouds play a major role in the Global Hydrological Cycle; more than 90% of precipitation in mid- to high- latitudes originate from such clouds. At high-latitudes there is also a significant fraction of precipitation occurring in the form of snowfall. The natural variability of snow particle sizes, number concentrations, shapes, and densities makes ice clouds and snowfall one of the biggest
challenges not only for weather and climate modelers but also for observationalists.

Following the success of the 1st International Summer Snowfall Workshop that took place in 2017 in Cologne, we are organizing the second meeting which will be held at the University of Helsinki Hyytiälä Station for Measuring Forest Ecosystem - Atmosphere Relations. The main focus of the workshop will be on connecting observations and models of ice clouds and precipitation. This includes improving parametrizations of ice microphysics needed for cloud models and remote sensing retrievals, linking ice particle physical and scattering properties, as well as advances in measurements by both in situ and remote sensing.
The workshop will be organized as a mixture of oral and poster presentations, invited overview talks and panel discussions.
