European Centre for Medium-Range Weather Forecasts

Headquartered in Reading in the UK, and with its data centre in Bologna, Italy, ECMWF is an independent intergovernmental organization supported by 34 Member and Co-operating States across Europe and holds the largest archive of numerical weather prediction data in the world. Its primary mission is to provide its users with numerical weather predictions covering medium to long ranges. Over the past few years, ECMWF has also developed a strong partnership with the EU and is an entrusted entity for the implementation and operation of the Climate Change and Atmosphere Monitoring Services of the ground-breaking EU Copernicus Programme.
