v3 v4 24 24 * `U_prepoststep`: The name of the pre/poststep routine as in `PDAF_get_state` 25 25 * `U_next_observation`: The name of a user supplied routine that initializes the variables `nsteps`, `timenow`, and `doexit`. The same routine is also used in `PDAF_get_state`. 26 * `status`: The integer status flag. It is zero, if `PDAFomi_assimilate_global_nondiagR`is exited without errors.26 * `status`: The integer status flag. It is zero, if the routine is exited without errors. 27 27 28 28 Notes: … … 33 33 The user-supplied call-back routines are described on the page on [ImplementAnalysisGlobal implementing the analysis step of the global filters]. 34 34 35 It is recommended that the value of `status_pdaf` is checked in the program after PDAFomi_assimilate_global_nopndiagRis executed. Only if its value is 0 the initialization was successful.35 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. 36 36 37 37 PDAF also has a [PdafSimplifiedInterface Simplified Interface] providing the routine `PDAFomi_assimilate_global_nondiagR_si`. In the simplified interface, the name of the user-supplied routines have predefined names and do not appear in the call to `PDAFomi_assimilate_global_nondiagR_si`. More information on the pre-defined names is provided in the [ImplementAnalysisGlobal page on implementing the analysis step of the global filters].
