| | 3 | This page documents the routine `PDAF_assimilate_seik_si` of PDAF. |
| | 4 | |
| | 5 | `PDAF_assimilate_seik_si` is the variant of [wiki:PDAF_assimilate_seik PDAF_assimilate_seik] 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. |
| | 6 | |
| | 7 | The routine is typically called in `assimilate_pdaf` or directly in the model code. |
| | 8 | |
| | 9 | The 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. |
| | 10 | |
| | 11 | The interface when using the SEIK filter is the following: |
| | 12 | {{{ |
| | 13 | SUBROUTINE PDAF_assimilate_seik_si(status_pdaf) |
| | 14 | }}} |
| | 15 | with the following arguments: |
| | 16 | * `status_pdaf`: The integer status flag. It is zero, if `PDAF_assimilate_seik` is exited without errors. |
| | 17 | |
| | 18 | |
| | 19 | The routine calls several user-supplied call-back routines. They are described on the page on [ImplementAnalysisseik implementing the analysis step of the SEIK filter]. |
| | 20 | |
| | 21 | It 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. |
