European Centre for Medium-Range Weather Forecasts (ECMWF) The European Centre for Medium-Range Weather Forecasts is an intergovernmental organisation and research institute based in Reading, Berkshire that develops global numerical weather prediction systems and delivers operational weather forecasting services. It operates a leading ensemble forecasting model, provides the Copernicus Programme's Copernicus Climate Change Service input, and hosts large-scale supercomputing resources used by meteorological services across Europe and beyond.
The organisation was established in 1975 following discussions involving United Kingdom, France, West Germany, Italy, Netherlands, Belgium, Denmark, Luxembourg, Ireland, Norway, Spain, Portugal and other signatories aiming to pool resources for improved medium-range forecasting. Early development drew on work from institutions such as the Met Office, Météo-France, Deutscher Wetterdienst, Royal Netherlands Meteorological Institute, ECMWF-linked national centres, and research teams at European Organisation for the Exploitation of Meteorological Satellites and European Space Agency. Over subsequent decades the centre expanded membership, adopted ensemble forecasting pioneered by groups including Met Office researchers and European scientists such as those at University of Reading and Max Planck Institute for Meteorology, and integrated satellite data from platforms like Meteosat and NOAA series.
ECMWF’s core mission combines operational production of global medium-range forecasts with coordination of European research in numerical weather prediction. It provides deterministic and ensemble forecasts to member and cooperating states including United Kingdom, Germany, France, Italy, Spain, Sweden, Norway, Finland and others, supports forecasting centres such as SMHI, AEMET, DWD and KNMI, and supplies data used by agencies like European Centre for Research and Advanced Training in Scientific Computing and European Environment Agency. The centre also contributes to international efforts including the World Meteorological Organization and United Nations initiatives on climate services and disaster risk reduction.
ECMWF develops advanced data assimilation and model physics, building on algorithms such as 4D-Var and ensemble Kalman filter variants co-developed by researchers from Imperial College London, Oxford University, ETH Zurich, CNRS, MPI-GEOMAR, University of Hamburg and other European research centres. Its Integrated Forecasting System is subject to rigorous evaluation against models from Met Office Unified Model, GFS (Global Forecast System), JMA (Japan Meteorological Agency), Canadian GEM and NCEP. Research programmes frequently collaborate with institutions like University of Reading's meteorology department, EC-funded Horizon 2020 projects, European Research Council-backed teams, and centres such as KNMI and DWD. The centre's work influences studies in climate modelling at organisations including EC-Earth Consortium, Hadley Centre, and Institut Pierre-Simon Laplace.
ECMWF distributes a wide range of products including global reanalyses (e.g., ERA-Interim, ERA5), ensemble forecast fields, and model output statistics used by national services such as Met Éireann, AEMET, MeteoSwiss, MeteoFrance and Deutsche Wetterdienst. These datasets are critical to projects like the Copernicus Atmosphere Monitoring Service and Copernicus Climate Change Service, and are ingested by research groups at European Space Agency, NOAA, NASA and universities including UCL and TU Delft. Data assimilation incorporates observations from satellites such as Metop, Sentinel series, NOAA platforms, and in situ networks operated by organisations like ECMWF's member states' national meteorological services.
High-performance computing is central to ECMWF operations; the centre procures and operates petascale systems supplied by vendors used in procurement processes involving agencies like European Commission procurement frameworks and national procurement authorities. Supercomputing centres such as CSC — IT Center for Science (Finland), Jülich Supercomputing Centre, and national facilities in Germany, France, and United Kingdom inform hardware choices. The centre’s systems support the Integrated Forecasting System, ensemble generation, and reanalysis production, and interface with data centres including Copernicus Data Warehouse and archival partners like ECMWF-MARS.
ECMWF is governed by a council composed of representatives from its member states and cooperating states, including ministers or senior officials from United Kingdom, Germany, France, Italy, Spain and other European capitals. Operational leadership comprises a Director-General and senior management appointed by the council, working alongside scientific directors drawn from the European research community including affiliates from University of Reading, Max Planck Society, and CNRS. Funding comes from member state contributions, cooperating state fees, and project grants managed in coordination with bodies such as the European Commission, European Space Agency, and research funding organisations like the European Research Council.
ECMWF plays a central role in international meteorological collaboration, partnering with the World Meteorological Organization, United Nations Office for Disaster Risk Reduction, Copernicus Programme, European Space Agency, NOAA, NASA, and national services including Met Office, Météo-France, Deutscher Wetterdienst and KNMI. It contributes to global forecasting coordination through initiatives like the Global Producing Centres framework and collaborates on climate reanalysis with projects involving Hadley Centre, EC-Earth Consortium, and university consortia at ETH Zurich, Imperial College London, University of Oxford and University of Cambridge.
