Comparing hybrid data assimilation methods on the Lorenz 1963 model with increasing non-linearity

Comparing hybrid data assimilation methods on the Lorenz 1963 model with increasing non-linearity

We systematically compare the performance of ETKF-4DVAR, 4DVAR-BEN and 4DENVAR with respect to two traditional methods (4DVAR and ETKF) and an ensemble transform Kalman smoother (ETKS) on the Lorenz 1963 model. We specifically investigated this performance with increasing non-linearity and using a q...
