     3This page documents the routine `PDAF_put_state_etkf_si` of PDAF.
     6`PDAF_put_state_etkf_si` is the variant of [wiki:PDAF_put_state_etkf PDAF_put_state_etkf] 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.
     8The routine is typically called in `assimilate_pdaf` or directly in the model code.
     10The routines `PDAF_put_state_*` are used with the 'flexible' implementation variant of PDAF.
     11The general aspects of the filter specific routines `PDAF_put_state_*` 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]. For the 'fully parallel' implementation variant the alternative routines `PDAF_assimilate_*_si` are used.
     13The interface when using the ETKF is the following:
     15  SUBROUTINE PDAF_put_state_etkf_si(status_pdaf)
     17with the following arguments:
     18 * `status_pdaf`: The integer status flag. It is 0, if `PDAF_put_state_etkf_si` is exited without errors.
     21The routine calls several user-supplied call-back routines. They are described on the page on [ImplementAnalysisetkf implementing the analysis step of the ETKF algorithm].
     23It is recommended that the value of `status_pdaf` is checked in the program after `PDAF_put_state_etkf_si` is executed. Only if its value is 0 the initialization was successful.
