May & June 2018: Added Value Meetings

The motive:

Next meetings for further analysis of the individual sections of the paper.

These are follow-up meetings to the sessions of the Annual Meeting 2018 where the overall structure of the paper was worked on. Now, the aim is to define the individual chapters.

The dates:

Precipitation: 07.05. Hamburg (MPI)
Circulation: 24.05. Hamburg (Uni HH)
Clouds: 07.05. Köln (Uni Köln)
Parametrization: 11.06. Munich (LMU)

9 – 13 July 2018: 15th Conference on Cloud Physics / 15th Conference on Atmospheric Radiation

Venue: Hyatt Regency Vancouver, Canada
: 9 – 13 July 2018, Vancouver, BC

19 – 21 September 2018: Workshop on Ice crystal concentration: measurements, retrievals, sensitivities

Venue: University of Leipzig, Bibliotheca Albertina, Beethovenstr. 6, Leipzig
Date: 19 – 21 September 2018
Registration: until 6 July by email to johannes.quaas@we dont want - indicating a title in case you want to contribute a talk to the science discussion (15 slots, first come - first serve)

Topic: Ice crystal number concentration, Ni, is a quantity  that is of large interest for cloud radiative properties, a key variable to evaluate in atmospheric models, and central when studying sensitivities of ice clouds to perturbations.

We would like to invite to a two-day workshop on Ni (Wed 19 noon - Fri 21 September noon) in Leipzig:

- one day with invited lectures targeted at young scientists (PhD candidates +), and
- one day with scientific presentations and discussion on the topic.
Please click here for a preliminary agenda.

The workshop is supported by SPP 1294 "HALO" (

Fall 2018: Time for Module Meetings

In September 2018, the final stage of HD(CP)² begins - thus time again for all modules to meet:

  • S1: 17/18 Sep in Leipzig
  • S2: 18/19 Sep in Cologne
  • S3: 26/27 Sep in Leipzig or Hamburg
  • S4: 19/20 Sep in Karlsruhe
  • S5: tbd
  • O: tbd

8 - 12 October 2018: The future of weather prediction: developments and challenges across scales (Symposium)

Venue: Harnack-Haus in Berlin. The meeting is hosted by the Hans-Ertel Centre for Weather Research.

Date: 8 - 12 October 2018

Abstract submission: July 23. Note that space is limited and, if necessary, a selection will be made based on abstracts.

Registration: 31 August 2018

Topic: The goal of the symposium is to discuss cutting edge development related to weather forecasts, from basic research on atmospheric processes, new modeling and new observational strategies, to communication to society. The scientific program is made of five sessions related to: high performance computing, observations for convective-scale models, subgrid-scale processes, data assimilation and ensembles, as well as impact modeling and communication of risk and uncertainty.

More details on the sessions and on the symposium can be found online at:

Scientific organizing committee: Martin Göber, Cathy Hohenegger, Tijana Janjic-Pfander, Jan Keller, Daniel Klocke, Henning Rust, Juerg Schmidli, Annika Schomburg, Sabrina Wahl, Martin Weissmann
