Vienna, 28th June – 2nd July, 2022
Under almost tropical conditions in Vienna, nearly 100 hackathon participants hacked their way through the heat!
On the first day the participants were introduced to the world of the latest storm-resolving simulation output in an intensive data-handling workshop that culminated in a BBQ for early stage researchers along the riverside in Vienna. The next day, our host Aiko Voigt, professor in climate science at the University of Vienna, kicked-off the hackathon with a warm welcome and after updates from the modelling groups on recent Cycle 2 developments in the SR-ESMs IFS and ICON the door was opened for three intensive days of pure hacking.
Beside the hacking-as-usual, participants could broaden their horizon in Unconscious biases in science and learn about the history and future in km-scale modeling in evening talks and discussions held by Lena Vogelmann and Masaki Satoh respectively. In addition, 15 external early stage researcher joined us to tackle the renewable energy challenge problem in collaboration with stakeholders from the renewable energy sector, with a workshop held by our Storms&Society lead in-between.
After almost four days of hacking and impressive results, the Cycle 2 Hackathon was rounded up in a nextGEMS hike and with continuous discussions and planning of the Cycle 3. Looking forward to meet everyone again at the Cycle 3 Hackathon in Madrid in May 2023!
Good news! We have a postdoctoral position open in nextGEMS!
The Portuguese Weather Service (IPMA) in Lisbon is recruiting a PostDoc (f/m/d) in the framework of the H2020 project nextGEMS. Focus of the work is the characterization of the land surface at very high-resolution and its representation in the ECMWF model and on the use of earth observations (particularly land surface temperature) to assess the realism of SR-ESMs (ECMWF & ICON).
The contract is expected to start in September 2022 with a maximum duration of 3 years.
In this years Scientific image contest 2022 held by Helmholtz Imaging of the Helmholtz Association one of our nextGEMS members Nikolay Koldunov from AWI won the 1st place for his contribution „Europe in winds“!
The image shows wind gusts over Europe as simulated by the nextGEMS climate model IFS with a 4km spatial resolution in the atmosphere. Wind gusts are overlayed by the zonal wind component for shading, which is plotted in gray-scale and made transparent. There is no explicit plotting of land, the high resolution allows for the land to „shine through“ due to larger surface friction and hence smaller wind speeds. The darker the area the smaller the wind is.
This particular image has several interesting features:
(i) a long stretch (hundreds of kilometers) of relatively calm winds in the wake of Jan Meyen island,
(ii) atmospheric fronts stretching for thousands of kilometers across the North Atlantic Ocean, and
(iii) strong winds in the Adriatic including a Bora event.
Visualisations like this will help scientists to identify and analyse interesting weather events, including extreme events, extract corresponding information from the modelling system and develop better understanding of Earth’s weather and climate.
If you have further questions about this image, feel free to contact Nikolay.
18 students and 7 professors from the University of Madrid started the month April with a weekend-hackathon. In two ways, they were testing new terrain. On the one hand, the students used ICON simulation output from our most recent nextGEMS simulations with 10.5 simulated months at 5km resolution, leading to 522 TB on disk. On the other hand, they analyzed this huge amount of data on DKRZ’s new supercomputer Levante.
Accepting the challenges, the students worked in small groups on a variety of topics ranging from the Madden-Julian Oscillation in the tropics to extratropical climate and from stratospheric biases high up in the atmosphere, passing by orographic-induced weather phenomena, all the way down to ocean-atmosphere interactions. Their contribution will help us to further shape the upcoming model development by investigating remaining biases and defining features that are well captured by the model.
A big thanks to the UCM professors for making this happen und to everyone participating for diving into the nextGEMS world and adding a piece to the bigger puzzle of understanding global storm-resolving simulations!
With the upgrade and relaunch of our website we also move to a new project design and community identity.
The new logo is colored in blue linking to our blue planet Earth. The rhombs emobdy gems (next Generation Earth Modeling Systems), beginning with four gems representing the four project themes whose roots extend through work packages up to the individual project members. Through a sencond lense, this refinement from four gems to many small ones equally symbolizes the grid refinement towards km- and storm-resolving simulations. In addition, the arrangement of the four main gems into one big gem nicely depicts the mutual interaction between our research themes and the necessity of all components to interact for a realistic representation of our Earth system.
With this renewed design, our community can identify itself with the brand nextGEMS even more.

Hackathons are communal exploration, analysis and development activities – all various forms of ‘hacking’. They prioritize working together over lecturing one another. At NextGEMS meetings, our fingers will do the talking.”
Our Hackathon goes into the 2nd Cycle! This time it takes place Tue 28th of June until Sat 2nd of July in Vienna, hosted by Prof. Aiko Voigt from the University of Vienna.
In the spirit of what was written in our proposal, participants will sit together in groups of 5-10 people working on a topic. The topics will be related to the four NextGEMS research themes, as well as to one wind energy challenge problem. We will all explore those topics based on the new Cycle 2 simulations run by the IFS and ICON model, identify bugs and improvements, and ultimately prepare for the Cycle 3 runs. If you havn’t been to a hackathon, have a look at our Cycle 1 hackathon video to get an impression of the atmosphere during our first Hackathon in October.
If you are interested in participating in the Hackathon, please register here.
We have a limit of 80 people and will give priority to the core NextGEMS scientists and programmers. Nevertheless, we hope that this will leave enough space for friends and advisors of the project and we explicitly invite everyone related to NextGEMS to register. We will let external people know by mid-April whether we have enough capacity to accommodate for their participation.
On the 3rd of March, the newest high performance computer system named Levante at the German Climate Computing Centre (DKRZ) started its operation.
Now, longer simulations can be run with a quadruplicated computing power.
Levante represents a step change in computing,[…], it will allow us to open new frontiers in climate science.
-Prof. Bjorn Stevens
Since the supercomputer is a core tool for this project, the operation of Levante enables simulations for physical processes on small-scale and the refinement of Earth system models down to 2.5km reduces parametrizations.

Our contest of the science art project is over now and it was a success! Some beautifully artistic outputs were created and they were put together into the nextCalendArt 2022. This calendar provides a glimpse into the beauty of the first simulation runs within the project by our two models IFS and ICON. Have a look at the result here.
Many thanks to the contributor:
J. Bao, M. Fielding, L. Kluft, N. Koldunov, L. Linardakis, T. Rackow and I. Sandu.
Submit your piece of art showing any aspect of working with high-resolution earth system model simulations now!
When starting to work with the nextGEMS simulation output, you will certainly produce new and exiting figures. We would ask you to think about them also in a different way: even if it doesn’t show what you intended, does it look like it could hang in a museum? Like a piece of modern art? Maybe only a couple of tweaks are necessary.
If you would like to contribute to this project, please send an email to Yuting before November 7. Please add a short title and describe in one or two sentences the scientific context of your simulation. The plot shall not show any axes, labels, legends, but give more a focus on the artistic value.
Amazing time in Berlin – nextGEMS held it’s first project meeting in form of a hackathon 19.–22. October in Berlin.
The first Cycle 1 simulations with the two earth system models (ESMs) ICON and IFS finished just in time for the hackathon participants to explore the high-resolutions runs. In only three days of hacking, about 80 participants from the nextGEMS project and friends showed a steep learning curve in working with high-resolution earth system model output. In groups of about five people, the teams were investigating current and in some cases urgent questions related to the four project themes Storms and Radiation, Storms and Land, Storms and Ocean, and Storms and Society. The results of the hackathon will guide us to the improved Cycle 2 simulations that will be run in the upcoming months.

Today was the official start of our nextGEMS Project, funded by CINEA within the European Union’s Horizon 2020 climate projects. Our digital kickoff-meeting with 122 international participants gave us not only a brief overview about the project itself but also emphasized the task to make science available for the broader user community.
Bjorn Stevens and Irina Sandu, our coordinators, opened the meeting with an insight about the pressing question how climate responds to warming and how we are going to solve existing and upcoming problems with the Next Generation Earth Modelling System. For this, two Storm-Resolving Earth System Models (SR-ESMs) will be developed and analyzed from three different themes: Storms and Radiation, Storms and Ocean as well as Storms and Land. Those themes will test emerging and long-standing hypotheses, underpinning our understanding of climate change. Further, the scientific accomplishments will couple the SR-ESM simulations with impact-sector modelling to work with users beyond the climate science community and put it into social context by the theme Storms and Society. Additionally, a newly established video communication concept, which will accompany the lifetime of the project will visualize the project for the broader user community.
The afternoon session started with a talk about our project embedded in the H2020 projects followed by a status and outlook of recent progresses and achievements in the development of the SR-ESMs. After the talks, participants had the chance to meet in smaller groups, get to know each other, and to discuss their ideas for first steps in the project.
All in all, the start of the project was very productive and everyone is highly motivated to tackle the upcoming challenges of the project.
