LE SERVICE OPÉRATIONNEL CMEMS IBI-MFC AUJOURD'HUI : EXAMEN DES PRINCIPALES RÉALISATIONS AU COURS DE LA PHASE DE SERVICE DE COPERNICUS-1 (2015-2021)

International audience; The CMEMS IBI-MFC (Iberia-Biscay-Ireland Monitoring & Forecasting Centre) delivers daily ocean model forecasts, analysis and reanalysis of different physical and biogeochemical parameters for the Atlantic façade, supporting all kind of marine applications. Along Copernicus-1, this IBI operational service has continuously evolved, upgrading both its forecast capabilities (in 2015, only a circulation forecast in place; today, 3 operational services, including waves and biogeochemical forecasts) and its multi-Year production (covering altimetric era with ocean and wave reanalysis products, together with a non-assimilative biogeochemical hindcast). The main IBIMFC operational achievements and product upgrades are here reviewed. An overview of main IBI service milestones, in terms of both operational production (with inclusion of new variables, increase of product resolution and temporal frequency, extension of forecast horizons and reanalysis coverages) and product quality enhancement is provided. The IBI model applications are routinely validated through meaningful skill scores and a wide range of statistical metrics computed to quantitatively assess the quality and reliability of these model solutions. The CMEMS IBI-MFC delivers today a reliable operational service, meeting user needs for a widespread end-user community (with strong IBI-ROOS connections and marked by a high number of ‘regular’ operational users linked to downstream services). The IBI-MFC service is expected to be upgraded, already in a Copernicus-2 context, and major guidelines of the roadmap are here outlined.
