Copernicus Marine Environment Monitoring Service (CMEMS) evolution: new and innovative ocean data assimilation techniques

Summary

The research and innovation activities aim to advance data assimilation techniques for improved ocean monitoring and forecasting. Key areas include coupled data assimilation across ocean components (like ocean-biogeochemistry or ocean-sea-ice), and the development of multi-scale methods capable of handling high-resolution and high-frequency observations. There is a focus on improving the estimation of uncertainties in analyses and forecasts, as well as incorporating Artificial Intelligence for tasks like model error correction and ensemble generation. The integration of new types of satellite and in-situ observations, and tools to assess the impact of these observations, are also essential. Furthermore, software infrastructure must evolve to support diverse assimilation methods and AI, while validation protocols and intercomparison methods will help evaluate the effectiveness of new approaches.

Detailed Call Description

The areas of R&I to address the above expected outcomes include:

  • Coupled data assimilation (e.g. between ocean and biogeochemistry, ocean and sea-ice, ocean and waves and atmosphere) to control in a more consistent way the ocean state variables across ocean components or forcings and to get more benefits from observations;
  • Development of multi-scale methods capable of assimilating high-resolution and high-frequency observations as well as of constraining larger scales;
  • Development of methods to produce reliable estimation of analysis and forecast uncertainties;
  • Use of Artificial Intelligence techniques in data assimilation schemes (e.g. use of emulators for ensemble generation, model error estimation, bias correction, separation of scale and model parameter estimation);
  • Use of new types of observations (e.g. new Sentinel Expansion and Next Generation missions, new in-situ observations) or higher-resolution of existing data streams;
  • Development of methods and tools to systematically assess the observing system impact in data assimilation systems (e.g. analysis and forecast sensitivity to observation);
  • The development of software infrastructure that can accommodate different assimilation methods (including artificial intelligence techniques), and facilitate the sharing of algorithms and optimization of computer codes (assimilation schemes) on high-performance computers;
  • The development of validation and intercomparison protocols to estimate and quantify the benefits of improved assimilation methods and integration of new observations (e.g. data challenges, use of OSSEs).

Eligibility For Participation Notes

A number of non-EU/non-Associated Countries that are not automatically eligible for funding have made specific provisions for making funding available for their participants in Horizon Europe projects.

If projects use satellite-based earth observation, positioning, navigation and/or related timing data and services, beneficiaries must make use of Copernicus and/or Galileo/EGNOS (other data and services may additionally be used).

The Joint Research Centre (JRC) may participate as member of the consortium selected for funding.
