Observing System Simulation
Experiment (OSSE)
Objective: A series of twin
experiments were made to examine the effectiveness of the Ensemble Kalman
Filter data assimilation to restore the true ocean state after initial
perturbation.
In OSSE:
1.The true ocean: the forward model
results;
2.The false ocean: the forward
model results with perturbed initial field without the
assimilation;
3.The assimilation analysis: the
assimilated results with inclusion of observation;
Twin experiments:
Case 1: with an initial perturbation in
surface wind forcing
Case 2: with an initial perturbation in
surface heat flux
Case 3: with an initial perturbation in the
T/S field
