Kerstin würde sich freuen, wenn Ihr den Blog auch in Eure Communities teilt bzw. weiterschickt.
Expedition drawing on Spitsbergen
Kerstin Heymach will take part, as a droughtswoman, in the (AC)³ Expedition on Spitsbergen/Svalbard for nearly a month, starting from May 29th, 2017.
She accompanies scientists of the contributing universities of Leipzig, Bremen, Cologne, the Institute for Tropospheric Research (TROPOS) and of the Alfred Wegener Institute (AWI) on their aircraft campaign ACLOUD and related research work in Longyearbyen and Ny Alesund by drawing, taking photographs and writing texts.
For that purpose she writes a WordPress blog. For those who want to virtuelly come with her without getting cold feet: http://www.arktis-zeichenblog.eu. Fans of social media could perhaps give a like to the site: https://www.facebook.com/arktiszeichenblog/ to join her.

First balloon tests in Melpitz
Our researches are currently testing their equipment and instruments for the tethered balloon measurements at the TROPOS measurement site in Melpitz, Germany. These tests were also attended and reported by a journalist from “Sächsische Zeitung”. The online arcticle can be found here. The tethered balloon experiment will be conducted during the ice station experiment ABEX within the expedition PASCAL in the Arctic in summer 2017.

Our (AC)³ member Klaus Dethloff, AWI Potsdam, is co-author of a paper recently published in Nature Climate Change: Nonlinear response of mid-latitude weather to the chanching Arctic.
Abstract: Are continuing changes in the Arctic influencing wind patterns and the occurrence of extreme weather events in northern mid-latitudes? The chaotic nature of atmospheric circulation precludes easy answers. The topic is a major science challenge, as continued Arctic temperature increases are an inevitable aspect of anthropogenic climate change. We propose a perspective that rejects simple cause-and-effect pathways and notes diagnostic challenges in interpreting atmospheric dynamics. We present a way forward based on understanding multiple processes that lead to uncertainties in Arctic and mid-latitude weather and climate linkages. We emphasize community coordination for both scientific progress and communication to a broader public.

WORKSHOP: Arctic snow, sea ice properties and interaction with the atmosphere
Dates: 6th – 8th of November 2017
Location: AWI Bremerhaven – Glashaus, building F (Bussestraße 24)
On behalf of the Transregional Collaborative Research Center TR 172 “ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms (AC )³“ we cordially invite you to attend the Topical Workshop on “Arctic snow and sea ice properties and interaction with the atmosphere” which will take place in Bremerhaven, Germany from 6 to 7 November 2017. One aim of the topical workshop is to strengthen the goals of the upcoming aircraft campaign PAMARCMiP (April 2018). A preparation meeting of PAMARCMiP will followed the workshop from 7 to 8 November.
Snow and sea ice albedo are essential to quantify the Arctic energy budget. Only small changes in surface albedo can trigger feedback mechanisms which enhance the Arctic sea ice loss. However, the snow and sea ice albedo are influenced by a multitude of parameters, such as snow grain size, black carbon concentration, surface roughness, the presence of leads and melt ponds, snow and sea ice thickness and the presence of clouds. Therefore, the local optical and physical properties of snow and sea ice have to be well characterized. Especially, aerosol particles including black carbon may alter the snow optical properties but still raise scientific questions like: What are the most relevant sources of aerosol particles contribution to the
reduction of snow albedo? How are aerosol particles transported into the Arctic and deposited to the surface? How aerosol particles interact with the cloudy atmosphere and are scavenged or modified along the transport path? These questions can be answered only by a collaborative effort of different types of measurements and modeling activities that together will capture the full picture of snow-atmosphere interactions.
