-This routine is only used for the LEnKF.
 
-The interface for this routine is:
-{{{
-SUBROUTINE localize_covar_pdafomi(dim_p, dim_obs, HP, HPH)
+This is a call-back routine for PDAF-OMI. It applies covariance localization in the LEnKF to the matrices PH^T and HPH^T, which are intermediate results of the EnKF. The routine calls a routine from the observation module for each observation type.
 
-  INTEGER, INTENT(in) :: dim_p                 ! PE-local state dimension
-  INTEGER, INTENT(in) :: dim_obs               ! Dimension of global observation vector
-  REAL, INTENT(inout) :: HP(dim_obs, dim_p)    ! Matrix HP
-  REAL, INTENT(inout) :: HPH(dim_obs, dim_obs) ! Matrix HPH^T^ 
-}}}
-
-The routine is called during the analysis step and has to apply the element-wise Schur product for the covariance localization of the two matrices'''HP''' and '''HPH^T^''', which are provided as input/output arguments.
-
-With PDAF-OMI, the routine just calls a routine provided by PDAF-OMI. 
+See the [wiki:OMI_Callback_obs_pdafomi documentation on callback_obs_pdafomi.F90] for more information.
