Do you find yourself at conferences drinking coffee alone? Do you seem to miss every chance to network? Or do you have the feeling you can’t keep the conversation going or can’t even start it in the first place? No matter if you answer one of those questions with a clear “ or you simply have the feeling that you could perfect your self presentation skills, then this seminar might be just right for you! From the first impression you leave, the conversation that follows to a friendly follow up on and offline all of this will be covered during this seminar.
This is an interactive workshop with a lot of exercises and real life examples. There is a special emphasis on communication, networking and media usage. The participants will be asked to prepare and debrief each session, submit written and recorded work to the trainer and also provide peer to peer feedback to other participants.
The workhsop is limited to 12 participants.
For (AC)³ members: Participation fee of 50 EUR per person will be covered by (AC)³ Gender funds.

In order to fully exploit the (AC)³ observations – here with a focus on the first field campaign results from the ACLOUD and PASCAL campaigns, but open for additional ideas – we are planning 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 offer 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).
The workshop is scheduled for two days. On Monday, 20 November, we will have 3 seperate topical meetings at different locations:
- Modelling group meets @ Vor dem Hospitaltore 1 –> Modelling group agenda
- ACLOUD group meets @ Prager Str. 34 –> ACLOUD group agenda
- PASCAL group meets @ TROPOS, Permoser Str. 15 –> PASCAL group agenda
On Tuesday, 21 November, we will have a joint meeting at TROPOS.
Workshop agenda (continuosely updated)
On Monday evening we will have a joint dinner at Moritzbastei Leipzig from 7 pm to start lively discussions between all groups.

8th Advanced Training Module (ATM) of Leipzig Graduate School on Clouds, Aerosols and Radiation (LGS-CAR). We have invited 3 international keynote speakers giving lectures on Polar Mid-Latitude Linkages Caused by Arctic Amplification.
ATM Agenda (continuously updated)
Location: Bremerhaven, Glashaus, building F (Bussestraße 24)
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.

The winter school is an advanced course intended for graduate students and researchers who want to receive
up-to-date knowledge on the observation and modeling of clouds and precipitation, with a specific focus on
Arctic and high-latitude clouds. The course is structured around a combination of lectures and hands-on
experience using data from research-grade radars (US DOE ARM and ACTRIS), in situ sensors and state-ofthe-
art models. The course topics include: cloud and precipitation observations (cloud radars, lidars, solar
and microwave radiometers, in situ sensors), cloud modeling, precipitation formation, boundary layer
modeling.
Some expressions from the winter school:
2016
The 2nd annual (AC)³ General Assembly (GA) meeting will take place from December 1st to 2nd, 2016 in Potsdam (Germany).
The Early Career Scientist and PIs will present their scientific highlights from the first year. During breakout group discussion, the (AC)³ participants will report and discuss on onging collaborations with other Cluster groups and upcoming campaigns.

The ACLOUD workshop took place from 21st to 22nd of November, 2016 in Bremen (Germany).
The ACLOUD campaign will take place from May 22nd to June 28th, 2017. The AWI Polar 5 and Polar 6 research aircrafts will be deployed in Ny-Ålesund.
In order to prepare this measurement campaign, about 30 researchers from Germany (University of Leipzig, University of Köln, University of Bremen, University of Mainz, AWI, TROPOS), and France (OPGC University) took part in the workshop. Most of the participants are key international ACLOUD PIs, aircraft instrument scientists and (AC)³ researchers who will all actively take part in the ACLOUD campaign or use the data for their research.
The following items have been discussed during the workshop:
- presentation of science questions and discussion of case studies
- refining flight strategies
- discussion about the ACLOUD procedures, the work plan and the interface between the different groups (instruments, flight facility, flight planning)
- presenting the local infrastructure in Ny-Ålesund
- discussion about a common visualization domain and a common projection
The many lively discussions between theoretical meteorologists, instrument scientists, pilots and students taking part in the campaign made this workshop a successful meeting.

PhD Workshop: An Introduction into Linux/Unix and Programming with FORTRAN 14. – 17.07.16 in Leipzig
When interacting with a server or computing cluster, the use of the command line (e.g. the Lunix terminal) is essential. Many of these servers are using a Linux system, or a system that can be handled in a similar way and are not accessible with a graphical user interface (GUI). The knowledge about the functions ot the terminal will make it a powerful tool for everyda work, not only when interacting with computing centres but also with peronal Linux/Unix machines.
FORTRAN is still one of the most commonly used programming languages in the field of meteorology/climatology. Its performance makes it useful for modelling as well as for data handling and analysis.
This workshop will give a short introduction into theses fields through exercises and coaching. It will be held by PhD students who are experienced users.
The workshop is capped at 14 participants for room capacity reasons.
The Kick-off PhD meeting of (AC)³ tooks place from June 1st to June 2nd, 2016 at Kloster Nimbschen, Grimma (Germany).
