     3This page documents the routine `PDAFomi_put_state_lnetf_nondiagR_si` of PDAF which is used in case of a non-diagonal observation error covariance matrix. This routine was introduced with PDAF V2.3.
     4
     5The routine is typically called in `assimilate_pdaf` or directly in the model code.
     6
     7`PDAFomi_put_state_lnetf_nondiagR_si` is the variant of [wiki:PDAFomi_put_state_lnetf_nondiagR PDAFomi_put_state_lnetf_nondiagR] 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.
     8
     9This 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 'flexible' implementation variant. In the 'fully-parallel' implementation variant of the data assimilation system the routines `PDAFomi_assimilate_*` are used.
     10
     11The interface is the following:
     12{{{
     13  SUBROUTINE PDAFomi_put_state_lnetf_nondiagR_si(status_pdaf)
     14}}}
     15with the following arguments:
     16 * `status_pdaf`: The integer status flag. It is zero, if the routine is exited without errors.
     17
     18The 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].
     19
     20It is recommended that the value of `status_pdaf` is checked in the program after thie routine is executed. Only if its value is 0 the initialization was successful.
