GFI / BCCR Seminar Erlend Moster Knudsen: Hunting high and low: Measuring Arctic amplification with an icebreaker, two airplanes, several ground-based instruments and three dozens scientists

The two concerted field campaigns ACLOUD and PASCAL took place near Svalbard May 23 - June 26, 2017. Focusing on studying Arctic clouds and related feedbacks, they used the icebreaker Polarstern, the airplanes Polar 5 and 6 and the station Ny-Ålesund. In his presentation, Dr. Knudsen will share some first results from the campaigns, highlighting the dominating short-term variability in the synoptic development relative to the long-term background effect of the Arctic amplification. This includes anomaly analyses of cold air outbreaks and warm air advections observed during the campaigns. Finally, the presentation discusses the results in light of similar Arctic field campaigns (e.g., N-ICE2015) and its implications for the advancing Arctic scientific understanding.
