    33This page documents the routine `PDAF3_assimilate_local`. The routine is part of the advanced [wiki:PDAF3_interface PDAF3 interface] that was introduced with PDAF V3.0.

    5 The routine is used to execute the analysis step of all local ensemble filters including the nonlinear filter LNETF, the hybrid filter LKNETF, and the ENSRF/EAKF (but except the [wiki:ImplementAnalysislenkfOmi LEnKF]). The routine uses the functionalities provided by PDAF-OMIto yield a small number of arguments. For backward-compatibility, the routine does not use PDAFlocal, but lets the user provide the routines for filling the local state vector and to fill the global analysis state vectors with the local analysis states.

For backward-compatibility, the routine does not use PDAFlocal, but lets the user provide the routines for filling the local state vector and to fill the global analysis state vectors with the local analysis states. This routine exists only for backward-compatibility. We recommend to use the routine [wiki:PDAF3_assimilate] that uses also PDAFlocal.

    77The routine is typically called in `assimilate_pdaf` or directly in the model code.
