The CONFESS Consortium is comprised of 4 partners from 4 European countries (International/United Kingdom, France, Spain, Italy). Through ECMWF, the reach is extended beyond these 4 countries due to the member and cooperating states of this international organisation of European Interest.

The partnership presents a well-balanced mixture of operational and research centres (ECMWF, Meteo-France, BSC) and research centres (CNR-ISAC) necessary to address the challenges of the CONFESS project.

In particular:

• The consortium is coordinated by the world-leading global weather prediction centre, which was founded by its member states to focus European excellence in a single organisation. Moreover, ECMWF is the entrusted entity for both the Copernicus Climate Change Service (C3S) as well as the Copernicus Atmosphere Monitoring Service, and has the leading expertise in Reanalysis.
• Meteo-France (MF) is the French national meteorological service, and its research department primarily made of the Centre National de Recherches Meteorologiques (CNRM) has an excellent track record in research activities ranging from meteorology to climate prediction and projections, as well as upper ocean, surface hydrology and atmospheric modelling. Meteo-France is a provider for the Copernicus Climate Change Service (C3S) for operational seasonal predictions.
• Barcelona Supercomputing Centre (BSC), the national supercomputing centre in Spain, is a centre of excellence on e-Science, with a multidisciplinary research team with a strong Earth Sciences department, including climate prediction and atmospheric composition.  BSC has a track-record on the evaluation of seamless predictions through a deep analysis of the strengths and weaknesses of state-of-the-art climate forecast systems and the most up-to-date observational datasets.  BSC counts with strong expertise on atmospheric composition, and is actively involved in climate model development with the EC-Earth European climate model.
• The Institute of Atmospheric Sciences and Climate of CNR excels on the scientific understanding of the climate system following multidisciplinary approach across Earth System components, modelling and observations.  It has a track-record of research work targeting the water cycle, climate variability, extremes and hotspots. EC-Earth is the modelling platform to integrate developments on land and vegetation modelling.
