  • PDAF3_put_state_global

    v2 v3  
    77The routine is typically called in `assimilate_pdaf` or directly in the model code.

    9 The general aspects of the filter specific routines `PDAF3_put_state_*` are described on the page [ModifyModelforEnsembleIntegration Modification of the model code for the ensemble integration] and its sub-page on [InsertAnalysisStep inserting the analysis step].

    1111The routine is used for the offline mode of PDAF. It can also be used in the 'flexible' parallelization implementation variant of the data assimilation system, but starting with PDAF-3 we recommend to use [wiki:PDAF3_assimilate_global PDAF3_assimilate_global], which is also used with the 'fully-parallel' implementation variant.

    2121 * `U_init_dim_obs_pdafomi`: The name of the user-supplied routine that initializes the observation information and provides the size of observation vector
    2222 * `U_obs_op_pdafomi`: The name of the user-supplied routine that acts as the observation operator on some state vector
    23  * `U_prepoststep`: The name of the pre/poststep routine as in `PDAF_get_state`
     23 * `U_prepoststep`: The name of the user-supplied pre/poststep routine as in `PDAF_get_state`
    2424 * `status`: The integer status flag. It is zero, if `PDAFomi_put_state_global` is exited without errors.
    2525
    2626**Note:**
    2727 * The routine is identical to the routine `PDAFomi_put_state_global` of PDAF 2. The new name reflect consistency with `PDAF3_assimilate_global`. If one has used `PDAFomi_put_state_global` before one can just adapt the name of the called routine.
    28 
     28 * To use the localization in the LEnKF, one needs to call [wiki:PDAFomi_set_localize_covar] in the observation modules to initialize the localization information.
    2929The user-supplied call-back routines are described on the page on [ImplementAnalysisGlobal implementing the analysis step of the global filters].
