Quantifying and reducing uncertainties in ocean models through data assimilation are essential steps towards accurate oceanic simulations and forecasts. Data assimilation and forecasting products based are now widely used in a variety of applications ranging from guiding maritime transportation, planning recreational activities, and supporting hazard and emergency responses. The challenges in this area are numerous due to the nonlinear dynamics and interactions at multiple spatio-temporal scales, computational burden, and diverse sources of uncertainties in the numerical models and observations. The goal of this session is to provide a forum for presenting and discussing recent developments in ocean data assimilation and forecasting methodologies, applications and assessments. Contributions concerning the following issues are of particular interest:
- Developments of new data assimilation methodologies;
- New developments, assessments and original applications of ocean data assimilation, operational and reanalysis systems;
- Pushing the limits of prediction skill, through stochastic parameterizations and accounting for model errors;
- Coupled data assimilation, including ocean-atmosphere and ocean-biogeochemical systems;
- Estimation and uncertainty quantification of ocean model parameters, inputs, and outputs;
- Assimilation of new datasets and design of observation systems.
