PO51C:
Developments and Ocean Applications of Data Assimilation, Uncertainty, and Sensitivity Analyses I


Session ID#: 9520

Session Description:
Data assimilation and uncertainty and sensitivity analyses are vital components in the production of ocean science reanalyses for the study of various ocean processes. They are also used in model calibration (including parameter estimation), design of observation systems, and for operational forecasts and analyses. The challenges in this area are numerous due to the non-linear interaction of multiple spatio-temporal scales as well as uncertainties due to the resolution of physical processes, parameterizations, and uncertain inputs. The goal of this session is to bring together researchers working in the areas of ocean data assimilation, model sensitivity analysis, and uncertainty quantification, with the goal of discussing new technical developments and recent applications. Contributions concerning the following issues are particularly of interest:

-       New developments and original applications of data assimilation, uncertainty and sensitivity analyses methods

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

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

-       Developments of advanced ocean operational and reanalysis systems

-       Assimilation of new data sets and design of observation systems
