     3This page documents the routine `PDAF_assimilate_lestkf_si` of PDAF.
     4
     5The routine is typically called in `assimilate_pdaf` or directly in the model code.
     6
     7The 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.
     8
     9The interface when using the LESTKF is the following:
     10{{{
     11  SUBROUTINE PDAF_assimilate_lestkf_si(status_pdaf)
     12}}}
     13with the following arguments:
     14 * `status_pdaf`: The integer status flag. It is zero, if `PDAF_assimilate_lestkf` is exited without errors.
     15
     16The routine calls several user-supplied call-back routines. They are described on the page on [ImplementAnalysislestkf implementing the analysis step of the LESTKF algorithm].
     17
     18It is recommended that the value of `status_pdaf` is checked in the program after PDAF_assimilate_lestkf is executed. Only if its value is 0 the initialization was successful.
