The rigorous testing and validation of ocean models (physical and biogeochemical) is a critical aspect of MOIRAI. Hindcast-based validation serves as a robust methodology for assessing the performance of these models by comparing simulated historical data with observed data, enabling the verification of model accuracy and areas for improvement. By validating high-resolution ocean physics models, the project facilitates future multi-decadal assessments of climate change risks and impacts in coastal areas.
MOIRAI’s improved and validated models, integrating inter-basin exchanges will feed future basin-scale predictions and evaluation of European seas’ carbon sequestration potential. The incorporation of uncertainty quantification through inter-comparison adds a layer of robustness to the models, acknowledging the inherent variability and limitations within the predictions, thereby improving the reliability of long-term projections.
MOIRAI will perform both a multi-scale and a multi-resolution comparison to quantify the added value of higher-resolution models and the advantages of regional or global models respectively, which will permit feedback on MOIRAI’s own improvements and on a more global scale. This comprehensive approach will contribute significantly to our ability to anticipate and address the complex challenges posed by climate change in oceanic environments.
