 The general aspects of the filter specific routines `PDAF3_assimilate_*` are described on the page [ModifyModelforEnsembleIntegration Modification of the model code for the ensemble integration] and its sub-page on [InsertAnalysisStep inserting the analysis step].

  * `status`: [[BR]]The integer status flag. It is zero, if the routine is exited without errors.

 **Note:**
  * The routine is identical to the routine `PDAFomi_assimilate_global` of PDAF 2. The new name reflects consistency with `PDAF3_assimilate_local`. If one has used `PDAFomi_assimilate_global` before one can just adapt the name of the called routine.
