The project covers the validation and intercomparison of the next generation of global ocean reanalyses for the Copernicus Marine Service.
39 months da 03/04/2025 a 30/06/2028
General aims
The project will evaluate and validate the Global ocean Reanalyses Ensemble Product (GREP) compare with other existing ocean reanalyses. The quality of the data and possible value for their application will be assessed for seven use cases: Meso-scale Eddies, Ocean Transports and Budgets, Atlantic Meridional Overturning Circulation (AMOC), Ocean Heat Content, Sea Level Changes, Marine Heatwaves, and Sea Ice and Volume.
The activities in this project support the UN Ocean Decade Marine Environment Reanalyses Evaluation Project.
CMCC role
CMCC leads the task on marine heatwaves, and contributes to tasks on sea ice change, meso-scale eddies, ocean heat content, AMOC
Activities
• Comparison with independent observations (e.g. satellite-derived or in-situ) to understand ability of reanalyses to capture ocean processes.
• Inter-comparison between GREP and other global reanalyses
Expected results
The validation of reanalyses will extend from previous studies on single variables (e.g. temperature), to processes (e.g. marine heatwaves). This output will contribute to future Ocean State Reports and proposals of new ocean monitoring indicators (OMI). The project team will participate in the cross-cutting activities carried out in Copernicus Marine Services.
