Dear all,

I like to draw you attention to the upcoming Arctic Science Summit Week in Prague (31 March - 7 April 2017,, where we will organize a session on "Arctic clouds, aerosols and climate effects" (see abstract below). Please join us by submitting an abstract of your work by December, 16th. Thanks!

Kind regards,

Session: 3. Arctic clouds, aerosols and climate effects

Convener: Takashi Yamanouchi, Paul Zieger, Julia Schmale

Clouds, water vapour and aerosols are closely linked through various dynamic, microphysical and chemical processes and feedbacks, and are strongly controlling the climate. There is a strong indication that low level and mixed phased clouds are an important driver of climate warming in the Arctic. Atmospheric aerosols, natural or anthropogenic origin, are forming clouds by acting as cloud condensation nuclei or ice nucleating particles. Arctic aerosols are mainly observed as the Arctic Haze and long-range transport tracers; Little is known about natural Arctic aerosol sources, such as primary marine aerosol or new particle formation and biomass burning. Clouds and the relative influence of aerosols and atmospheric dynamics on their microphysical and radiative properties are not yet well understood. Recently, strong emphasis is laid on the study of clouds, aerosols and climate at e.g. Ny-Ålesund, Svalbard and other location throughout the Arctic. These activities will improve the understanding and modelling of climate processes in the Arctic and contribute to prediction studies like “Year of Polar Prediction” (YOPP/PPP/WMO). The session is dedicated to the interplay of these key players in the Arctic atmosphere. It will cover latest results from-long-term observations, field experiments, modelling studies and upcoming new studies throughout the Arctic
