= PDAFomi_store_obs_l_index = This page documents the routine `PDAFomi_store_obs_l_index` of PDAF-OMI. This routine has been added with PDAF V2.3. This routine is used for the case that a user implements a user-provided alternative for the routine `PDAFomi_init_dim_obs_l`, which initializes the local observation information for PDAF-OMI in `thisobs_l` for a single local analysis domain. The routine can to be called in `init_dim_obs_l_OBSTYPE` in each observation module if a domain-localized filter (LESTKF/LETKF/LNETF/LSEIK/LKNETF)is used. || See the [wiki:OMI_search_local_observations page on user-provided initialization of local observations] for the full description of a user-provided routine to intialize local observations. || The interface is: {{{ SUBROUTINE PDAFomi_store_obs_l_index(thisobs_l, idx, id_obs_l, distance, & cradius_l, sradius_l) TYPE(obs_l), INTENT(inout) :: thisobs_l ! Data type with local observation INTEGER, INTENT(in) :: idx ! Element of local observation array to be filled INTEGER, INTENT(in) :: id_obs_l ! Index of local observation in full observation array REAL, INTENT(in) :: distance ! Distance between local analysis domain and observation REAL, INTENT(in) :: cradius_l ! cut-off radius for this local observation ! (directional radius in case of non-isotropic localization) REAL, INTENT(in) :: sradius_l ! support radius for this local observation ! (directional radius in case of non-isotropic localization) }}} '''Notes:''' * `idx` is usually the counte over the valid local observation of the observation type in the observation module * `cradius_l` and `sradius_l` are usually the same for all local obsevations of a single type if the localization is isotropic * While using this routine can be more convenient than doing the initialization of the variables in `thisobs_l` in the user code, in our tests the code ran faster when we did not use this routine, but did this initialization in the user code.
