Data Assimilation Experiments
1)Optimal Interpolation (OI) assimilated all T/S data into the model  as monthly arrays
2)
2)Ensemble Kalman Filter to assimilate all T/S data into the model as adaptive samplings
Examples were made for the 1998 hindcast reanalysis experiment
Note: The ensemble Kalman filter experiment results were made by the graduate student Xue and he is in hospital, so the results are not included in this talk.
