2025 marked the first year for the WeatherGenerator project, with major advances across all areas - from model architecture to expanded datasets and growing community engagement. Let’s have a look at some of the project’s highlights of the year.
Join Us in Oslo – WeatherGenerator Dissemination Workshop 2026! We are excited to announce the upcoming WeatherGenerator Dissemination Workshop for everyone working with climate data, environmental modelling, and weather-related decision-making. 📍 Location: Hybrid - Online and in Oslo, Norway 📅 Date: 11 February 2026 The day event will open with a summary of the project, followed by detailed discussion with the project partners on the WeatherGenerator achievements. Invited guest speakers will highlight the relevance and usage of the WeatherGenerator and its tools / applications, and we will also have highlight presentation from related international efforts in the area of foundation modelling for weather and climate science.
Explore the New WeatherGenerator Theme Videos We are excited to introduce a brand-new collection of videos that takes you behind the scenes of the WeatherGenerator project. Four Theme Videos – each dedicated to one core pillar of the initiative – along with an overall summary video are now available on our website. Each Theme Video highlights a key element of the project: Theme 1: From Raw Data to Ready-to-Use Inputs This video explores how the project brings together diverse climate and weather datasets, transforming them into a unified, scalable foundation tailored for machine-learning workflows.
Video Highlights from Our First Hackathon We are pleased to share highlights from WeatherGenerator’s first internal hackathon, held from 27–29 August 2025 in Bonn, Germany at ECMWF. Over the course of three days, around 40 researchers, developers, and application partners from across Europe came together to collaborate, exchange knowledge, and lay the foundation for one of the EU’s most ambitious AI-for-climate projects. From data foundations to real-world applications, the hackathon was not only about technical progress, but also about building connections, sharing insights, and shaping the future of climate intelligence.
WeatherGenerator’s Sister Projects WeatherGenerator is one of three projects launched in January and February 2025 under Horizon Europe to strengthen Destination Earth (DestinE), Europe’s initiative to build a high-precision, interactive digital twin of the Earth. Digital twins are computational models of real-world phenomena that can be used to simulate the past, model the present, and predict the future. Together with TerraDT and UrbanAIR, we expand the DestinE ecosystem by addressing different but complementary aspects of the Earth system.
What are Supercomputers? Supercomputers are high-performance computing systems designed to solve problems which exceed the capacity of conventional machines. Their defining feature is massive parallelism: instead of relying on a single processor, they connect tens of thousands of CPUs and GPUs which perform calculations simultaneously. This parallel architecture allows them to reach speeds measured in petaflops (10¹⁵ operations per second) or even exaflops (10¹⁸ operations per second), enabling computations that would take years on a standard computer to be completed within hours or days.
