European Centre for Medium-Range Weather Forecasts - ECMWF

This summer the Copernicus Atmosphere Monitoring Service (CAMS), which is implemented by ECMWF, released the Assessment Report on European Air Quality 2025. On the occasion of the 𝗜𝗻𝘁𝗲𝗿𝗻𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗗𝗮𝘆 𝗼𝗳 𝗖𝗹𝗲𝗮𝗻 𝗔𝗶𝗿 𝗳𝗼𝗿 𝗯𝗹𝘂𝗲 𝘀𝗸𝗶𝗲𝘀, let’s take a look at some of the key findings:  • Air quality continues to improve in Europe, with emissions of key air pollutants declining across the continent  • Over the past decade, emissions of sulphur oxides and nitrogen oxides have fallen by approximately 3-5% per year across the EU  • The most significant reductions have been achieved in industry and road transport The CAMS Air Quality report provides a clear indication that air quality policies are working. At the same time, it demonstrates that year-to-year variations in weather conditions can significantly influence pollution levels, even as long-term trends continue to improve.

ECMWF is taking part in this year’s Annual Meeting of the European Meteorological Society (EMS) in Utrecht, the Netherlands, and online. Our staff are participating in a broad range of sessions, covering topics such as AI and physics-based forecasting, weather and climate extremes, Earth system data, hydrology, data assimilation, and more.

What does the future hold for high-performance computing at ECMWF? ECMWF is preparing for its next HPC facility, planned for installation in 2027. It will be designed to support both physics-based and AI-based forecasts and provide dedicated resources for training machine-learning models, reflecting the growing role of AI in weather forecasting.

🌍🌐 New Climate Digital Twin impact sector data is now available via the DestinE Platform. Developed as part of the European Commission’s Destination Earth (DestinE) initiative, the Climate DT integrates impact-sector applications directly into its production workflow. This allows climate simulations and sector-specific information to be produced together at kilometre-scale spatial resolution and hourly temporal resolution. The newly released data covers: 🔋 Renewable energy  🔥 Wildfires  💧 Hydrology  🌧️ Extreme precipitation The applications translate kilometre-scale climate simulations into sector-specific indicators and information designed to support climate adaptation and decision-making.  The Climate DT is implemented by a broad European partnership led by CSC - IT Center for Science, working in close collaboration with ECMWF.

Satellites have transformed weather forecasting. At ECMWF, they provide the vast majority of observational information behind Earth-system analyses and reanalyses, filling gaps where conventional observations are sparse. The next generation of satellite missions, alongside better ways of using available observations and advances in AI, will allow ECMWF to extract more value from every measurement. This will support more accurate forecasts for Member and Co-operating States and for society. Find out how ECMWF turns satellite data into trusted weather predictions ➡️ https://lnkd.in/ejiRWg93

We’re excited to join this years Adopt AI - Grand Palais Conference as an official partner.   On 3–4 December in Paris, we will share how ECMWF is working with its Member States and European partners to advance the use of AI for weather and climate, including through the operational Artificial Intelligence Forecasting System (AIFS), open-source Anemoi framework and AI activities within the European Commission’s Destination Earth (DestinE) initiative.

🌍🌐 Meet the experts of Destination Earth (DestinE): Fernando Iglesias-Suarez is part of the team developing a machine learning (ML) climate emulator for the DestinE initiative of the European Commission.   As a climate scientist and scientific coordinator of the team developing the Climate Emulator within DestinE, Fernando works at the intersection of climate science and machine learning.   The climate emulator uses machine learning to reproduce key aspects of the detailed, physics-based simulations produced by the Climate Change Adaptation Digital Twin (Climate DT), but at a much lower computational cost. It also aims to seamlessly integrate different components of the Earth system, including the atmosphere, ocean and land.   A team led by Predictia Intelligent Data Solutions is developing the climate emulator, together with the Barcelona Supercomputing Center, the Spanish National Research Council (CSIC) and Forschungszentrum Jülich (FZJ), in collaboration with ECMWF.   ▶️ Watch the full video: https://lnkd.in/e7cwGquc
