Registration now open for the WeatherGenerator Community Hackathon

The WeatherGenerator Community Hackathon 📍 Location: Max Planck Institute for Biogeochemistry, Jena, Germany 📅 Date: 26–28 January 2027 📝 Registration: 1 September – 1 November 2026, via REGISTRATION Join our first Community Hackathon and become part of the WeatherGenerator community! The WeatherGenerator project will host its first Community hackathon on 26–28 January 2027 in Jena, Germany. This in-person, hands-on event will bring together researchers and professionals working across Earth System sciences to explore the WeatherGenerator, exchange ideas and become part of its growing community. The goal is that each participating team can run and fine-tune the WeatherGenerator for its own application while learning from and contributing to the community around the open-source model. The WeatherGenerator is an open-source European foundation model of the Earth system aiming to provide new machine-learned Digital Twin for Destination Earth. It is developed by 16 partners in a Horizon Europe project coordinated by ECMWF. The WeatherGenerator learns an unified latent representation from a wide variety of Earth system datasets - reanalyses, model output, satellite products and in-situ observations - using a self-supervised, masked-token approach. Rather than training a separate model for their task, users can use this general WeatherGenerator foundation model and fine-tune it towards the outputs that matter for their application.

Science Explainer #2: What is representation learning?

What is representation learning and how does it support smarter weather forecasting? Sophie Xhonneux from ECMWF explores exactly that in the second WeatherGenerator Science Explainer. The atmosphere is measured continuously by satellites, weather stations, and balloons, producing vast, overlapping datasets. Rather than training separate models on all of this data, WeatherGenerator learns a compressed, unified representation that captures the underlying physics of the atmosphere, enabling more efficient and powerful forecasting across applications.

Science Explainer #1: Can weather models predict power prices?

In the first instalment of the WeatherGenerator Science Explainer series, Even Nordhagen from Norwegian Meteorological Institute explains how the WeatherGenerator goes beyond traditional weather models, directly predicting energy - relevant variables like wind power output and reservoir inflow, without the need for separate downstream models. With a built-in long-term memory, the system can track slow-building processes like snowpack and soil moisture, and ultimately learn the full chain from atmospheric conditions to electricity markets.

Video Highlights from Oslo

From 10–12 February 2026 WeatherGenerator project partners and participants met at Forskningsparken – Oslo Science Park, as well as online, for a dynamic programme combining an internal General Assembly, a public Dissemination & Stakeholder Day, and a hands-on Coding Workshop. The programme covered the technical foundations of WeatherGenerator: its architecture, training approach, data formats and applications - alongside contributions from our sister projects TerraDT and UrbanAIR and invited speakers working on AI-driven approaches to weather and climate science, including foundation modelling.

Women in WeatherGenerator: Celebrating International Women's Day

Science advances through the courage to ask bold questions and across the WeatherGenerator project, women are at the forefront of asking them. From developing the core AI architecture to adapting it for real-world applications in energy, health, and extreme weather forecasting, female researchers and engineers are shaping the future of AI-driven meteorology every day. WeatherGenerator is an EU Horizon project bringing together 16 leading European organisations to build a next-generation foundation model for weather and climate. Behind this mission is a diverse community of scientists, and on this International Women’s Day, we want to shine a light on some of the extraordinary women who make this project what it is. Coming from across the globe, bringing expertise in atmospheric chemistry, machine learning, probabilistic modelling, remote sensing, and operational meteorology.

Forecast Verification for AI Models - Article by Britta Seegebrecht and Sabrina Wahl

Forecast Verification for AI models Can we trust AI models? This question could be from a sci-fi movie but nowadays it becomes more and more relevant since so called artificial intelligence (AI) based on machine learning (ML) has made its way into a vast range of application fields from marketing to costumer services, from medical assistance to quality control – and weather forecasting is no exception. For predictions of the weather conditions this question translates roughly to: ‘How accurate and reliable is the forecast, where and under which conditions/for which situations?’ These questions are targeted by the field of forecast verification.What is forecast verification and why is it important?

WeatherGenerator’s Sister Projects

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.

Supercomputers in the WeatherGenerator

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.
