+This page documents the routine `PDAFomi_assimilate_global_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. 
+
+The routine is typically called in `assimilate_pdaf` or directly in the model code.
+
+`PDAFomi_put_state_global_nondiagR_si` is the variant of [wiki:PDAFomi_put_state_global_nondiagR PDAFomi_put_state_global_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.
+
+This routine is used with [wiki:PDAF_OMI_Overview PDAF-OMI] to execute the [ImplementAnalysisGlobal analysis step with global (non-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. 
+
+The interface is the following:
+{{{
+  SUBROUTINE PDAFomi_put_state_global_nondiagR_si(status_pdaf)
+}}}
+with the following arguments:
+ * `status_pdaf`: The integer status flag. It is zero, if the routine is exited without errors.
+
+The routine calls several user-supplied call-back routines. They are described on the page on [ImplementAnalysisGlobal implementing the analysis step of the global filter algorithms].
+
+It is recommended that the value of `status_pdaf` is checked in the program after the routine is executed. Only if its value is 0 the initialization was successful.
