U_localize_covar_serial
v2 v3 4 4 5 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 code 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 parallelization6 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 index `iobs` related to 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 required for parallelization. 7 7 8 8 The interface is the following:
