nextGEMS is an European project that follows a new approach to climate modelling with global storm-resolving Earth-system Models. The project members meet regularly at hackathons to collaboratively analyse the latest model runs, exchange ideas and develop new ways forward.
We would like to include universities and research groups, especially from regions with less of a tradition in climate science. External participants applying for a stipend will (mostly) be organized in teams to work on an Application Challenge Problem, this time related to fisheries. nextGEMS scientists, as well as experts from the fisheries field, will supervise and support those teams.
If you haven’t been to a hackathon, have a look at our Cycle 1 and Cycle 2 hackathons to get an impression of the atmosphere during our previous meetings.
We welcome young scientists with a strong interest in climate science or Earth system informatics!
The hackathon participation is free and includes coffee breaks, lunches and a dinner. Additional travel and accommodation costs (incl. breakfast) up to €1000 are available per stipend.
Before applying for a hackathon stipend, please prepare the following documents:
Information on the hackathon, as well as registration details, can be found on the event website.

Today, the first of September 2022, marks the One-year anniversary of nextGEMS! On this occasion we have held a seminar to look back into this first year. We have collected quite a diverse list of accomplishments: around 80 nextGEMS members to date, 2 hackathons, as well as 2 little-hackathons, two babies and a third one on it’s way within our nextGEMS community, over 600 followers on Twitter, 16 videos and 1 NextCalendArt.
Around 70 participants joined the online session, being welcomed by Bjorn Stevens and Irina Sandu with an insight into the project and a discussion on the suprises, bumps and hurdles of the past year. They were followed by the updates and perspectives from the four project themes: Storms&Radiation, Storms&Land, Storms&Ocean and Storms&Society.
Even when struggling with technicalities and a challenging workflow, it is always fun to tackle these hurdles within the nextGEMS community, to encounter bumps and to learn from going over them. This anniversary seminar has shown how projects such as nextGEMS contribute to the advancement of climate science through the improvement of modelling performances in ICON and IFS (see also our Blogposts).
We are also expecting changes in the year to come. Not only did the project office get expanded but a sister project is born as well: the WarmWorld project – Better | Faster | Easier is joining the efforts of nextGEMS. In addition, our weekly Office Hours are changing format and are now Storms&Science, with our subthemes organizing theme-related science talks and discussions.
The preparation for our Cycle 3 hackathon is already at full speed. Following the spirit of the Cycle 2 hackathon, we will come together once again in Madrid at the end of May 2023 and round up the model development phase, before the application phase starts.

Under the cloudy skies of the Swedish summer, the members of the WP6 group gathered on a beautiful remote island on the Gullmarsfjorden – Stora Bornö. The long hours of intensive work and discussion during the day were rewarded by scenic starry nights, both above and below, thanks to the local bioluminescent algae. This environment motivated an inspired and thorough evaluation of the two ocean mixing schemes, a turbulent kinetic energy (TKE) and an empirical K-profile (KPP) based scheme. Using sensitivity experiments of the uncoupled ICON and FESOM runs, we have discovered that biases in the model output cannot be attributed to a single mixing scheme. While TKE was slightly better on large scales, KPP was better at reproducing some local processes such as near-inertial wave induced mixing.
We also uncovered biases in the ERA5 forcing, and an interesting trend of the mixed layer becoming shallower with increasing model resolution. Aside from the analysis, we shared expert knowledge through lectures given by the professors in the group, and project presentations by the early career scientists. On the final days of the workshop, we also received two guest lectures: a master’s student from AWI, Jan Gärtner, explained how he coupled a sea ice component to the python-based ocean model Veros; and dr. James Avery gave a talk about the future of programming languages tailored for constructing comprehensive and transparent climate model code.

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!
*The Cycle 2 hackathon was co-funded by the EASiWACE2 project (European Union’s Horizon 2020 – grant agreement No 823988).
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.
