PDAFomi_assimilate_local_si

This page documents the routine PDAFomi_assimilate_local_si of PDAF.

The routine is typically called in assimilate_pdaf or directly in the model code.

This routine is used with PDAF-OMI to execute the analysis step with domain-localized filters. The routine is used in the 'fully-parallel' implementation variant of the data assimilation system. With the 'flexible' implementation variant, the routines `PDAFomi_put_state_*' are used.

The interface is the following:

  SUBROUTINE PDAFomi_assimilate_local_si(status_pdaf)

with the following arguments:

• status_pdaf: The integer status flag. It is zero, if PDAFomi_assimilate_local_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 local filter algorithms.

It is recommended that the value of status_pdaf is checked in the program after PDAFomi_assimilate_local is executed. Only if its value is 0 the initialization was successful.
