| | 3 | This page documents the routine `PDAF_generate_obs_offline` of PDAF. |
| | 4 | |
| | 5 | The routine is used for the offline coupled mode of PDAF, which is described on the page: [wiki:OfflineImplementationGuide Implementation Guide for Offline Coupling]. |
| | 6 | |
| | 7 | The interface is the following: |
| | 8 | {{{ |
| | 9 | SUBROUTINE PDAF_generate_obs_offline(U_init_dim_obs_f, U_obs_op_f, U_get_obs_f, & |
| | 10 | U_init_obserr_f, U_prepoststep, status_pdaf) |
| | 11 | }}} |
| | 12 | with the following arguments: |
| | 13 | * `U_init_dim_obs_f`: The name of the user-supplied routine that provides the size of the full observation vector |
| | 14 | * `U_obs_op_f`: The name of the user-supplied routine that acts as the full observation operator on some state vector |
| | 15 | * `U_get_obs_f`: The name of the user-supplied routine that receives the full vector of generated synthetic observations from PDAF |
| | 16 | * `U_init_obserr_f`: The name of the user-supplied routine that initializes the vector of observations error standard deviations for for full observation vector |
| | 17 | * `U_prepoststep`: The name of the pre/poststep routine as in `PDAF_get_state` |
| | 18 | * `status_pdaf`: The integer status flag. It is zero, if the routine is exited without errors. |
| | 19 | |
| | 20 | |
| | 21 | The user-supplied call-back routines are described on the [ImplementGenerateObs page on implementing the generation of synthetic observations]. |
| | 22 | |
| | 23 | 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. |
