    4147With PDAF-OMI many of the routines are general and hence usable for all filter algorithms. There are some differences between the local and global filters and the LEnKF.  The general routines will be repeated, but they are marked as general.

    43 There are three different routines that call the filter analysis step:
    44  * [ImplementAnalysisGlobal Implementation of the analysis for Global Filters]
    45  * [ImplementAnalysisLocal Implementation of the analysis for Local Filters]
    46  * [ImplementAnalysislenkfOmi Implementation of the analysis for the LEnKF using covariance localization]

     51There are three different routines that call the filter analysis step.
     52 * [ImplementFilterAnalysisOverview General overview] of routines required to implement the analysis step for ensemble filters.

    4857For the application of the 3D-Var methods there are separate routines (added with PDAF 2.0):
    49  * [wiki:ImplementAnalysis_3DVar Implementation of the analysis for 3D-Var with parameterized background covariance matrix]
    50  * [wiki:ImplementAnalysis_3DEnVar Implementation of the analysis for 3D Ensemble Var ]
    51  * [wiki:ImplementAnalysis_Hyb3DVar Implementation of the analysis for hybrid 3D-Var]

     66PDAF-OMI was introduced with version 1.16 of PDAF. While we recommend using OMI, the [wiki:ImplementationofAnalysisStep_noOMI implementation of the analysis step without OMI] is still possible.
