Investigation of Local Weighting Filtering on Randomization Technique Estimates in a Data Assimilation System

Investigation of Local Weighting Filtering on Randomization Technique Estimates in a Data Assimilation System

Mainstream numerical weather prediction (NWP) centers usually estimate the standard deviations of background error by using a randomization technique to calibrate specific parameters of the background error covariance model in variational data assimilation (VAR) systems. However, the sampling size o...
