The European Centre for Medium-Range Weather Forecasts (ECMWF) is an international organisation supported by 34 States: 22 Members (Austria, Belgium, Croatia, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Serbia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom) and 12 Co-operating Members (Bulgaria, Czech Republic, Estonia, the former Yugoslav Republic of Macedonia, Hungary, Israel, Latvia, Lithuania, Montenegro, Morocco, Romania and Slovakia). ECMWF’s principal objectives are threefold. The production, on a regular basis, of medium-range and long- range weather forecasts for distribution to the meteorological services of the Member States is ECMWF's primary obligation. Scientific and technical research directed at the improvement of these forecasts is crucial to achieving ECMWF's commitment to stay at the forefront of global weather prediction. Finally, ECMWF undertakes the collection and storage of appropriate meteorological data. ECMWF’s computer facility includes supercomputers, archiving systems and networks. ECMWF has maintained and developed computationally demanding software since its creation 40 years ago. It has participated in a number of European projects relating to computing and HPC, such as CRESTA, ESCAPE, NextGenIO, and ESiWACE. In addition, in 2013, ECMWF initiated a Programme on Scalability that aims at developing the next-generation forecasting system addressing the challenges of future exascale high-performance computing and data management architectures.


ECMWF will participate in work package “Co-design applications”, which aims to demonstrate the usefulness of developments in other work packages. ECMWF will leverage the ESCAPE weather mini-apps, or dwarfs, in order to test and benchmark best practices for future heterogeneous systems, on NWP-related code and algorithms.
