🚀 Our #nextGEMS overview paper is out!

After three years of intense collaboration, we’re thrilled to share a comprehensive look at what the nextGEMS project has achieved: a milestone for #ClimateModelling 🌐

For the first time ever, nextGEMS has produced multidecadal #climate simulations with kilometer-scale resolution across the ocean, land, and atmosphere, using the ICON and IFS-FESOM Earth system models. 🌍

🔹 The project unfolded over four development cycles, each releasing new configurations of ICON and IFS-FESOM.
🔹 These were rigorously evaluated at our hackathons, bringing together climate scientists, software engineers, HPC experts, and users from sectors like energy and agriculture.
🔹 By the end of the fourth cycle, we successfully ran 30-year simulations (2020–2049) at an impressive ~500 simulated days per day on the Levante supercomputer at German Climate Computing Center | DKRZ |.
🔹 Simulations reached ~5 km resolution in the ocean and ~10 km on land and in the atmosphere, offering unprecedented detail.

Furthermore, the simulations form a core building block for the Climate Change Adaptation Digital Twin in the Destination Earth (DestinE) initiative. In other words, nextGEMS' work paves the way for the next generation of European climate research. 🇪🇺

🌍 Experience the Hamburg node at the WCRP Global KM-Scale Hackathon 2025 🎥

🗓️ In May, over 600 scientists and researchers joined forces across 10 global locations to take part in the first-ever global climate modelling #hackathon, organized by the World Climate Research Programme and supported by initiatives like WarmWorld, EERIE I European Eddy-Rich Earth System Models, Destination Earth, ESMO, and #nextGEMS.

🇩🇪 One of the largest nodes was hosted by the @MPI_Meteo in Hamburg📍 , where more than 120 participants from around the world came together. They spent a week collaborating with local science teams, exploring cutting-edge research, and working with data from the latest
#ICON and #IFS–FESOM model runs.

🌐 From Europe to Southeast Asia, Australia, and the Americas, this was a truly global effort to advance kilometer-scale #ClimateModelling.

🎬 Curious to see what it was like? We’ve captured the energy and collaboration of the Hamburg node in a short video. Come take a look!

🚨 Video alert! Our latest multimedia piece is out and we are excited to share it with you ▶️

🔎 What is this video about?: The visualizations in this video provide a colorful and creative representation of our modelling endeavors. Additionally, the captivating images demonstrate the playful fluctuations of various components of our Earth system, including clouds, aerosols, thermal radiation, and temperature, over the course of the present and future years — specifically between 2021 and 2030.

📽️ Video creation: This illustrative work has been produced with the Earth System models used by #nextGEMS: ICON and IFS-FESOM. #ICON is a model was developed by the @MPI_Meteo and the German Climate Computing Center, while hashtag#IFS-FESOM developed by the European Centre for Medium-Range Weather Forecasts.

🌍 Day 2 of the WCRP Global KM-Scale Hackathon 2025 is off to an incredible start!👩‍💻

📍 At the Hamburg node, participants have formed dynamic groups tackling topics like cloud climatology, aerosols, ice sheets, and more. Moreover, computing companies such as NVIDIA and climate modelling initiatives like DestinE Platform are also on-site, joining forces to push the boundaries of #ClimateScience. 💡

🔷 #nextGEMS is backing this groundbreaking global event, which brings together scientists, developers, students, and data experts from around the world to accelerate progress in kilometer-scale #EarthSystemModeling. 🌐

Today, the participants were able to get a close look at Levante, the Supercomputer at #DKRZ.

Levante has been operating since March 2022, increasing the computing capacity at DKRZ four-fold. Its main memory exceeds 800 Terabytes (about 100.000 Laptops) and the computing power 14 PetaFLOPS, which are mainly used for modelling purposes.

Thank you Florian Ziemen for the tour!
