Meetings

The PI planning meeting for discussion about the second phase of (AC)³ will take place in Bremen from January 15 – 17, 2019.

The agenda can be found here.

The meeting contributions can be found in the intranet.

The conference will summarize the scientific results obtained during the first three years of the Transregional Collaborative Research Center TR 172 on Arctic Amplification (AC)³, and will discuss them in context with the international research community. Distinguished guest speakers will talk about recent highlights and current hypotheses in the field of Arctic climate research. Talks and posters will be presented in five sessions corresponding to the five (AC)³ clusters. The (AC)³ “Best Poster Prize” will be awarded to Early Career Scientists. The conference is supposed to promote scientific exchange and identify key tasks to be addressed in near-future Arctic climate research. It is open to scientists presenting (AC)³ relevant topics, also beyond the framework of (AC)³.

The Call for Astracts is now open until 01 October 2018. Further information can be found here.

Please send your abstracts by email to admin[at]ac3-tr.de.

For the second phase of (AC)³ we are planning an airborne campaign using Halo for looking at Langrangian airmass transformations during moist-air intrusions and cold-air outbreaks.

A first Halo-(AC)³ planning workshop will take place in Berlin, 28 June 2018.

A description how to get to the Helmholtz Head Office can be found here.

The conference had the occasion to summarize the scientific results obtained during the first year of the
Transregional Collaborative Research Center TR 172 on Arctic Amplification (AC)³, and discussed them in context with the international research community. Distinguished guest speakers have talked about recent highlights and current hypotheses in the field of Arctic climate research. Talks and posters were presented in five sessions. The “(AC)³ Young Investigators Awards“ were awarded to 5 Early Career Scientists. The conference is supposed to promote scientific exchange and identify key tasks to be addressed in near-future Arctic climate research.

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.

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.

The PAMARCMiP kick-off meeting of (AC)³ took place from October 18th to October 19th, 2016 in Bremen (Germany).

Among the participants were 3 PIs, 6 Postdocs, 2 PhDs and 6 scientist from the participating (AC)³ institutes and partners from the Department of Environmental Science (ATPRO), University of Tokio (EPS), Niiggata University, and the University of Mainz (IPA).

The meeting has been the occasion to get to plan the aircraft campaign PAMARCMIP in spring or early summer 2018 from Station Nord, and to start collaborations within projects, between research areas and with the external partners.

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.
