چکیده

(DA). More or less it has been applied in the assimilation with real observations. Here the OTW in this study is applied in 3-dimension DA but not 4-dimension DA, which need address in the introduction. The citations of OTW are not very relevant (Page 2, line 13-15). I could not find the clear concept of OTW and how they applied in data assimilation. SO you should address the technique details in the paper. I guess that you treat all the observations independently and assimilate then sequentially using their original error scales. another approach is to assimilate the average values of the observations in the OTW. It is worth to compare these two approach in the study.

Impact of Optimal Observational Time Window on Coupled Data Assimilation: Simulation with a Simple Climate Model

Climate signals are the results of interactions of multiple time scale media such as the atmosphere and ocean in the 15 coupled earth system. Coupled data assimilation (CDA) pursues balanced and coherent climate analysis and prediction initialization by incorporating observations from multiple media into a coupled model. In practice, an observational time window (OTW) is usually used to collect...

A Study of Impacts of Coupled Model Initial Shocks and State–Parameter Optimization on Climate Predictions Using a Simple Pycnocline Prediction Model

A skillful decadal prediction that foretells varying regional climate conditions over seasonal–interannual to multidecadal time scales is of societal significance. However, predictions initialized from the climateobserving system tend to drift away from observed states toward the imperfect model climate because of the model biases arising from imperfect model equations, numeric schemes, and phy...
