 || The interface routines for the parameterized 3D-Var are specialized versions of the universal interface with a reduced number of arguments. If one implements both 3D Ensemble Var and parameterlized 3D-Var we recommend to use the [wiki:Implement3DVarAnalysisPDAF3Universal universal interface routines for 3D-Var]. ||
 
-The different 3D-Var methods in PDAF were explained on the [wiki:Implement3DVarAnalysisOverviewPDAF3 page providing the verview of the Analysis Step for 3D-Var Methods]. Depending the type of 3D-Var, the background covariance matrix '''B''' is represented either in a parameterized form, by an ensemble, or by a combination of both. The 3D-Var methods that use an ensemble need to transform the ensemble perturbations using an ensemble Kalman filter.

 For the analysis step of 3D-Var we need different operations related to the observations. These operations are requested by PDAF by call-back routines supplied by the user and provided in the PDAF-OMI structure.  in the call to the assimilation routines as was examplained on the [wiki:Implement3DVarAnalysisOverviewPDAF3 page providing the overview of the Analysis Step for 3D-Var Methods].
