     3This page documents the routine `PDAF_assimilate_seek_si` of PDAF.

     6`PDAF_assimilate_seek_si` is the variant of [wiki:PDAF_assimilate_seek PDAF_assimilate_seek] 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.
     7
     8The routine is typically called in `assimilate_pdaf` or directly in the model code.
     9
     10The general aspects of the filter specific routines `PDAF_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]. 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.
     11
     12The interface when using the SEEK filter is the following:
     13{{{
     14  SUBROUTINE PDAF_assimilate_seek(status)
     15}}}
     16with the following arguments:
     17 * `status`: The integer status flag. It is zero, if `PDAF_assimilate_seek` is exited without errors.
     18
     19
     20The routine calls several user-supplied call-back routines. They are described on the page on [ImplementAnalysisestkf implementing the analysis step of the ESTKF].
     21
     22It 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.
