v191 v192 111 111 **PDAFlocal** 112 112 113 [wiki:PDAFlocal ]113 [wiki:PDAFlocal_overview] 114 114 115 115 [wiki:PDAFlocal_set_indices] … … 210 210 * For even better performance of the initialization of local observations, we added ''support for a user-sided implementation of search for local observations''. The user-sided search routine can lead to the best performance since it requires less IF-checks which are required in the generic code inside PDAFomi. If you have the impression that PDAFomi_init_dim_obs_l is slow in your case, e.g. because it domines the run time of the analysis step, we recommend to aim for a user-sided implementation (see https://pdaf.awi.de/trac/wiki/OMI_search_local_observations) 211 211 * Addition of ''support for non-diagonal observation error covariance matrices in PDAF-OMI'' (see https://pdaf.awi.de/trac/wiki/OMI_nondiagonal_observation_error_covariance_matrices) 212 * ''Introduction of PDAFlocal interface''. This simplifies the implementation of the state localization. It also provides support for weighted local increments, e.g. to implement vertical localization or weakly coupled assimila ation.
