European Centre for Medium-Range Weather Forecasts

The European Centre for Medium-Range Weather Forecasts (ECMWF) is an independent intergovernmental organization providing advanced weather forecasts, climate data, and meteorological research services to European member states and the global scientific community. Based in Reading, UK, with additional facilities in Bonn, Germany, ECMWF operates one of the world's most powerful supercomputers for numerical weather prediction. The organization produces medium-range forecasts (3-10 days ahead), seasonal outlooks, climate reanalysis datasets, and specialized products for aviation, marine, and emergency response sectors. ECMWF's forecasts are widely used by national meteorological services, researchers, policymakers, and industries dependent on accurate weather intelligence. With cutting-edge science, data assimilation techniques, and international collaboration, ECMWF continues to advance the accuracy and reliability of weather forecasting across Europe and beyond.
