On the Efficiency of Covariance Localisation of the Ensemble Kalman Filter Using Augmented Ensembles
Localisation is one of the main reasons for the success of the ensemble Kalman filter (EnKF) in high-dimensional geophysical data assimilation problems. It is based on the assumption that correlations between variables of a dynamical system decrease at a fast rate with the physical distance. In the...
