    33The page document the user-supplied call-back routine `U_localize_covar_serial`, which was introduced with PDAF V3.0.
    44
    5 The routine `U_localize_covar_serial` is a call-back routine that has to be provided by the user. The typical name in the user codee is `localize_covar_pdaf`, but the user can choose the name of the routine.
    6 The routine is used in the ENSRF/EAKF and is called during the analysis step. The purpose of the routine is to apply covariance localization to the vectors '''Hi P''' and '''Hi PH^T''' for the assimilation of a single observation (determined by the observation operator '''Hi'''). Here '''Hi PH^T''' is for the vector relating to the observed covariance matrix for the full observation vector, which is reuired for parallelization
