Covariance Localization

Covariance Localization is a statistical filtering technique in data assimilation that belongs to the class of covariance regularization methods, distinguished by its use of spatially dependent weighting to suppress spurious correlations arising from limited ensemble sampling in ensemble-based state estimation, particularly when assimilating radar observations into numerical weather prediction models.
