     3This page documents the routine `PDAF_assimilate_estkf_si` of PDAF.
     5`PDAF_assimilate_estkf_si` is the variant of [wiki:PDAF_assimilate_esktf PDAF_assimilate_estkf] with the [PdafSimplifiedInterface simplified interface]. The difference between both routines is that in the simplified interface the names of the call-back subroutines are not specified. Instead the routine assumes that the call-back routines have a standard name as specified at the end of this page.
     7The routine is typically called in `assimilate_pdaf` or directly in the model code.
     9The general aspects of the filter specific routines `PDAF_assimilate_*_si` 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]. The routine is used in the fully-parallel implementation variant of the data assimilation system. When the 'flexible' implementation variant, the routines `PDAF_put_state_*' are used.
     11The interface when using the ESTKF is the following:
     13  SUBROUTINE PDAF_assimilate_estkf_si(status_pdaf)
     15with the following arguments:
     16 * `status_pdaf`: The integer status flag. It is zero, if `PDAF_assimilate_estkf` is exited without errors.
     18The routine calls several user-supplied call-back routines. They are described on the page on [ImplementAnalysisestkf implementing the analysis step of the ESTKF].
     20It is recommended that the value of `status_pdaf` is checked in the program after PDAF_assimilate_estkf is executed. Only if its value is 0 the initialization was successful.
