     37|| This page describes the implementation approach of PDAF2. This is intended for reference for existing implementations performed for PDAF2. See the [wiki:ImplementationofAnalysisStep_PDAF3 page on implementing the analysis step with PDAF3] for the updated recommendations. ||

    4039This documentation describes the implementation of 3D variational assimilation methods with OMI as it was standard since their introduction in PDAF version 2.0 and until and including PDAF version 2.2.1. With PDAF 2.3 we introduced the [wiki:PDAFlocal_overview PDAFlocal interface], which simplifies the implementation of the local analysis. This approach is described on the current page on the [wiki:ImplementAnalysis_3DEnVar_PDAF23 Implementation of the Analysis Step for 3D Ensemble Var with OMI].
