= PDAFomi_put_state_lenkf_si = This page documents the routine `PDAFomi_put_state_lenkf_si` of PDAF. The routine is typically called in `assimilate_pdaf` or directly in the model code. `PDAFomi_put_state_lenkf_si` is the variant of [wiki:PDAFomi_put_state_lenkf PDAFomi_put_state_lenkf] 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. This routine is used with [wiki:PDAF_OMI_Overview PDAF-OMI] to execute the [ImplementAnalysislenkfOmi analysis step of the localized EnKF]. The routine is used in the 'flexible' implementation variant. With the 'fully-parallel' implementation variant of the data assimilation system, the routines [wiki:PDAFomi_assimilate_lenkf_si PDAFomi_assimilate_lenkf_si] or [wiki:PDAFomi_assimilate_lenkf PDAFomi_assimilate_lenkf] are used. The interface is the following: {{{ SUBROUTINE PDAFomi_put_state_lenkf_si(status_pdaf) }}} with the following arguments: * `status_pdaf`: The integer status flag. It is zero, if `PDAFomi_put_state_lenkf_si` is exited without errors. The routine calls several user-supplied call-back routines. They are described on the page on [ImplementAnalysislenkfOmi implementing the analysis step of the localized EnKF]. It is recommended that the value of `status_pdaf` is checked in the program after PDAFomi_put_state_lenkf_si is executed. Only if its value is 0 the initialization was successful.
