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 PDAFomi_put_state_lenkf with the 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 PDAF-OMI to execute the 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 PDAFomi_assimilate_lenkf_si or 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 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.
