The organizing committee of the Topical Workshop on „Coal Mine Methane (CMM) measurements during CoMet” invited to topics focusing on the CoMet related measurements in Poland, and the corresponding data evaluation and modeling of the campaign period. In particular, preliminary results and work in progress was highly appreciated since the workshop was intended to give an overview over the unique data set and modeling activities, and to identify topics where different groups (instrumental and modeling, different platforms, etc.) can join forces. Time was used for discussions to foster bi- or multilateral cooperation.

CIRRUS-HL Kick-off Science Workshop
22 November 2018, 13:00 - 23 November 2018, 13:00
DLR, Institute of Atmospheric Physics (Building 120, Room 003), Oberpfaffenhofen, Muenchener Str. 20, 82234 Wessling, Germany
The scope of this meeting is to present scientific topics and interests of the partners, to discuss the instrumentation and flight strategy required to address those topics, forecast, links to satellites and ground stations, modeling activities, and international cooperations. On the second day, we will form topic groups on specific research questions and define responsabilities for the CIRRUS-HL white book. The CIRRUS-HL white book will then be written in the next months and provide a science base for submission of proposals to DFG within the SPP HALO in 2019.
Topical Workshop: 2nd Young Researcher NARVAL-II Synergy Workshop
14 - 16 November 2018
University of Cologne, Cologne, Germany
Developers of Global Climate Models (GCM) / Numerical Weather Prediction Models (NWP) and observationalists are two groups dealing with the overall topic of atmospheric physics but tend to live in two different worlds, hence, regarding the same thing through two different pair of glasses. By that, the interaction between the two groups is limited but also offers the possibility to enlarge the total perspective of describing the Earth atmosphere better.
Therefore, the 2 nd Young Researcher NARVAL-II synergy Workshop, a Topical HALO Workshop, was initiated. It took place at the University of Cologne from the 14 th to the 16 th November 2018, being gratefully funded by the HALO SPP 1942 of the German Research Foundation (DFG) and the Cologne Graduate School of Geosciences (GSGS). It offered 13 young researches the chance to meet each other, share ideas and to develop new approaches for joint working groups.
During the preparation phase, approximately one month before the Workshop, individual topics of each person were collected, which should be discussed during the meeting.
The first day of the workshop started with an introduction of the participants, explaining their scientific interest and background, their working topic, and the expectations on the meeting. Following the list of collected topics the most urgent issues on the list were selected and a working plan for the following days was created.
It showed quickly, that modelers and observationalists have unrealistic expectations. While measurement uncertainties were underestimated by the modelling community, the possible model quantities did not fit to the quantities measured by the instruments of the experimentalists. As a first conclusion the need for a comprehensive HALO remote sensing forward operator arised. By that, HALO would virtually fly through the weather model providing simulated quantities which can be directly compared with the observations gather from the real flights of HALO.
In course of the second day an overview was developed, listing the most important quantities which should be investigated, starting from water vapor, rain water content, and the cloud phase. These are one of the most uncertain parameters in GCM but simultaneously the most influencing.
In the second part of day two, interactive sessions followed, where individual groups of two to four participants worked on specific problems, like cloud detection by different active and passive remote sensing instruments and the representativeness of these observations for the model.
The third day was mainly determined by presenting and discussing the results of the individual working groups. At the end, everyone formulated their personally most important take-home message.
As a result of the workshop modelers and observationalists are now much more aware of possible problems and are able to consider the aspects of models and measurements in the model-setup, their simulations, and the construction of new instruments.
Nevertheless, the workshop also provided a fantastic chance to get familiar with each other in a way that could never be established just by mail and phone.
Topical Workshop on Ice crystal concentrations: measurements, retrievals, sensitivities

European Geosciences Union (EGU)
General Assembly 2018, 8 - 13 April 2018, Vienna, Austria
Apply for 2018 ARM Summer Training Event
Calling all graduate students and early career scientists!
The second ARM Summer Training and Science Applications event on observations and modeling of clouds and precipitation will take place July 14 to 21, 2018. The training will be held at the National Weather Center in Norman, Oklahoma.
Deadline to apply is March 30, 2018.
Sponsored by the ARM Climate Research Facility to support the next generation of atmospheric scientists, this training will cater to graduate students and early career scientists (within four years of receiving their PhD) who are interested in observations and modeling of aerosols and cloud and precipitation processes.
The summer training will provide theoretical and practical instruction on the application of ground-based observations from a wide array of active and passive sensors and will encourage innovative methods for using ARM facilities to address complex scientific inquiries.
Selected participants will have their accommodation expenses covered by the ARM Facility.
Read more about the topics that will be covered during the event.
Topical Workshop on the Processes and Composition of the UTLS
The workshop will be held from 7.-8. March 2018 at the JUFA Hotel in Jülich.
The goal of the topical workshop is to give a summary of the current research on the processes affecting the composition of the UTLS on the basis of the recent HALO missions. Key factors identified so far are the role of the Asian monsoon system, the role of the decaying vortex and processes at the extratropical tropopause as well as isentropic mixing at the jets. The meeting will identify gaps of current understanding to organize the next research steps. The results will particularly be used to sharpen the focus of upcoming UTLS HALO missions (SOUTHTRAC).
Specifically it is planned to give an overview of the scientific results from the HALO missions focusing on UTLS specific topics, which cover specifically aspects between the chemical composition and dynamics in the UTLS (TACTS/ESMVal, POLSTRACC/SALSA/GW Lifecycle, WISE, ...).
It is further planned to develop research strategies and concepts for future HALO missions. This may include joint or coordinated missions with other airborne platforms or satellite and model activities.

CoMet Topical Workshop
30 Nov. - 2 Dec. 2016
German Aerospace Center (DLR), Oberpfaffenhofen
CoMet is a mission to collect (active and passive) remote sensing and in-situ data from aircraft in order to gain new knowledge on the distribution and temporal variation of the two most important anthropogenic greenhouse gases, carbon dioxide and methane. These findings will help to better understand the global carbon cycle and its influence on climate. This airborne campaign using the German research aircraft HALO and small Cessna aircraft will take place in spring of 2017 in Europe.
The goal of the workshop is to bring together the mission participants and national and international experts from various fields related to the global carbon cycle both with a theoretical and experimental background for the benefit of the scientific data to be collected.
The workshop is expected to strengthen the link between the CoMet mission and the international greenhouse gas research communities.
