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
