Data assimilation into oceanic ecosystem models: a critical review, some comparisons, and recommendations
نویسنده
چکیده
This report aims to critically review the work carried out to-date on the assimilation of data into ocean ecosystem and coupled bio-physical models. The review is prompted by the newly available ocean colour data from SeaWiFS and OCTS, and their potential use for data assimilation to improve both the models and their predictive capabilities. In addition, some initial results on the comparison of three data assimilation methods (adjoint, simulated annealing, Markov chain Monte Carlo) are summarised. The comparison has been carried out using a twin experiment approach with a simple predator-prey model, in order to focus on the assimilation techniques rather than the complexities of the model. From the review and comparison conclusions are drawn regarding the state of data assimilation into oceanic ecosystem models, and recommendations made about possible future work on this problem.

Ecosystem models are valuable tools for understanding the growth of vegetation, its response to climatic change and its role in the cycling of greenhouse gasses. Data Assimilation (DA) of synoptic coverage Earth Observation (EO) data into ecosystem models provides a statistically optimal mechanism for constraining the model state vector trajectory both spatially and temporally. EO “products” su...
متن کاملCoupled Data Assimilation for Enso Prediction∗
An outstanding problem with present ENSO forecast systems is that most of them are initialized in an uncoupled manner, that is, no feedbacks are allowed between the ocean and the atmosphere during data assimilation and model initialization. Such an approach may produce realistic initial states, but not necessarily the optimal conditions for skillful forecasts, because model-data mismatch can ca...
