     3This page documents the routine `PDAFomi_assimilate_local_si` of PDAF.
     4
     5The routine is typically called in `assimilate_pdaf` or directly in the model code.
     6
     7This routine is used with [wiki:PDAF_OMI_Overview PDAF-OMI] to execute the [ImplementAnalysisLocal analysis step with domain-localized filters]. The routine is used in the 'fully-parallel' implementation variant of the data assimilation system. With the 'flexible' implementation variant, the routines `PDAFomi_put_state_*' are used.
     8
     9The interface is the following:
     10{{{
     11  SUBROUTINE PDAFomi_assimilate_local_si(status_pdaf)
     12}}}
     13with the following arguments:
     14 * `status_pdaf`: The integer status flag. It is zero, if `PDAFomi_assimilate_local_si` is exited without errors.
     15
     16The routine calls several user-supplied call-back routines. They are described on the page on [ImplementAnalysisLocal implementing the analysis step of the local filter algorithms].
     17
     18It is recommended that the value of `status_pdaf` is checked in the program after PDAFomi_assimilate_local is executed. Only if its value is 0 the initialization was successful.
