Tender description

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), issued a contract for a service related to the development of an ensemble of data assimilation for the ocean in support of climate services development, specifically the initialization of the ECMWF seasonal forecasts, and as part of a coupled ocean-atmosphere global reanalysis. ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), issued a contract for a service related to the development of an ensemble of data assimilation for the ocean in support of climate services development, specifically the initialization of the ECMWF seasonal forecasts, and as part of a coupled ocean-atmosphere global reanalysis. The development within this contract will advance the ocean data assimilation capabilities used in the initialization of seasonal forecasts and generation of coupled Earth System reanalyses. Both seasonal forecast and Earth System reanalyses are key elements of the Copernicus Climate Change Service. Specific targets of the contract are the better utilization of the Earth system observations by provision of more accurate reanalyses, and provision of reliable uncertainty estimates. The implemented developments are expected to be used in the production of the next generation of C3S’s Reanalysis System (ERA6), which will provide a monitoring capability for the Earth system, including atmosphere, land, ocean, sea-ice and ocean waves. Some of the developments will also contribute to the production of ocean initial conditions for the next ECMWF seasonal forecasting system SEAS6, by preparing ocean initial conditions spanning several decades, with corresponding uncertainty estimates. The ocean data assimilation will be based on the NEMO ocean model, on the NEMOVAR data assimilation system and it will use the (C++ based) Object-oriented prediction system (OOPS) infrastructure.
