OM14B:
Advances in Data Assimilation and Uncertainty Quantification for Ocean Forecasting and Analysis I Posters


Session ID#: 27795

Session Description:
Data assimilation and uncertainty quantification are vital for ocean forecasting and reanalysis. They are also widely used for model calibration (including parameter inference) and observation systems design. The challenges in this area are numerous due to the paucity of observations, nonlinear dynamics and interactions at multiple spatio-temporal scales, involved numerical dimensions, and also uncertainties due to the resolution of physical processes, parameterizations, and inputs. The goal of this session is to bring together researchers working on the development and applications of ocean data assimilation and uncertainty quantification to discuss recent advances in the field. Contributions concerning the following issues are of particular interest:

- New technical developments and original applications of ocean data assimilation and uncertainty quantification

- Pushing the limits of predictability, through stochastic parameterization and in term of targeting submesoscales and extended forecasting windows

- Coupled data assimilation, including ocean-atmosphere, ocean-waves and ocean-biogeochemical systems

- Estimation and uncertainty quantification of ocean models parameters, inputs, and outputs

- Estimating and accounting for ocean models errors

- Assimilation of new datasets and design of observation systems
