#1 Arctic Climate System
Date: Monday, July 06, 2020 10:00 – 11:00 a.m., online
Topic: Arctic Climate System
Lecturer: Manfred Wendisch
The lecture starts with a short motivation, why it is so important to study the fascinating processes driving the Arctic climate system. Then, a historical overview of the exploration of the Arctic is given, including famous ship expeditions starting 500 years ago until today. The next part includes a summary of current climate changes (sea ice, snow cover, ocean biology, near-surface air and upper ocean water temperatures, permafrost, sea level). Further on, the talk describes the interlinked and complicated feedback processes within the Arctic climate system with two major topics: clouds and meridional transports. In the end a brief summary is given.

Die Arktis verschwindet! – Wie wir der Eisschmelze auf die Spur kommen
Prof. Dr. Susanne Crewell
NEW DATE: 16 June 2020
Der Klimawandel erwärmt die Erde. Doch warum erhöht sich die Temperatur in der Arktis schneller als in anderen Regionen? Während sich global die bodennahe Temperatur um etwa ein Grad erhöht hat, sind die beobachteten Temperaturänderungen in der Arktis mehr als doppelt so hoch. Zeitgleich wird das Meereis dünner und in der Fläche weniger.

It has been a while since we all met to discuss the data analysis of ACLOUD. Now additional measurements from AFLUX are available.
Therefore, we propose a scientific workshop to continue and strengthen the interaction between the different measurement groups and the link to modelling activities.
Please note the following dates in your calender.
Begin: Monday 02.12.2019 start at noon 13:00
End: Wednesday 04.12.2019 until noon 12:00
Monday and Tuesday will be dedicated to ACLOUD/AFLUX data. This gives us at least 1 1/2 days and time for deep discussion. We hope these days will fit to your schedules and will allow a fruitful discussion.
On Wednesday morning we plan to talk about the upcoming MOSAiC airborne activities with Polar 5. Since the situation for the airborne activities changed dramatically, it is important to revisit the scientific idea and possible flight plans.
Further information will be announced later.

Workshop “ACLOUD & PASCAL model-data synergy”
In order to fully exploit the (AC)³ observations – here with a focus on the first field campaign results
from the ACLOUD & PASCAL campaigns, but open for additional ideas – we plan a dedicated workshop to bring together ACLOUD & PASCAL scientists (observations side) and modellers (from high-resolved / LES modelling to global climate modelling scale), as well as other interested (AC)³ scientists.
A preliminary workshop 14 October 2016 in Leipzig with participants just from different groups
from Universität Leipzig and TROPOS underlined the potential of, and the interest in, such activities.
We plan a first exploratory workshop on this topic a few months after the ACLOUD & PASCAL campaigns but early enough to still steer the work of (AC)³ PhD candidates in both, modelling and observations fields, and early enough to accomplish meaningful science in the sense of joint publications across institutes.
We will call for participation from colleagues who really intend to collaborate on specific model-data
synergy projects (in the sense of a workshop, not a conference).

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.

5 – 6 October: HALO-(AC)³ Workshop “Sharpening the Science objectives of HALO-(AC)³”
We are planning to apply HALO (High Altitude and Long-Range Research Aircraft) in the framework of the envisioned second phase of (AC)³ in March-April of either 2020 (during MOSAiC) or 2021. The objective will be to measure air mass transformations along their way from the inner Arctic to the open Arctic Sea. In particular, vertical profiles observations of meteorological, aerosol, cloud, and radiative energy budget parameters and their transformations along meridional air mass transports over sea ice has been conducted with a positive outcome. However, it is now time to specify and sharpen the scientific objectives of this mission and to write a White Book summarizing the aims. For this purpose we are planning a topical workshop.
Further information will follow soon.
