PDAF_local_type
v1 v2 5 5 The function is an alternative to the routine [wiki:PDAF_get_local_type]. Here the value is the return value of the function, while for `PDAF_get_local_type` the return value is an argument of the routine. 6 6 7 The function returns the information on the localization type of the select d filter. With this one can distinguish filterusing domain localization (LESTKF, LETKF, LSEIK, LNETF), covariance localization (LEnKF), or covariance localization with observation handling like domain localization (ENSRF/EAKF).7 The function returns the information on the localization type of the selected filter. With this one can distinguish filters using domain localization (LESTKF, LETKF, LSEIK, LNETF), covariance localization (LEnKF), or covariance localization with observation handling like domain localization (ENSRF/EAKF). 8 8 9 The function can be called in init_dim_obs_OBSTYPE, of each observation module to control whether [wiki:PDAFomi_set_localize_covar] is called to initialize covariance localization.9 The function can be called in `init_dim_obs_OBSTYPE`, of each observation module to control whether [wiki:PDAFomi_set_localize_covar] is called to initialize covariance localization. 10 10 11 11 The interface is the following: … … 19 19 * (3) covariance localization. but observation handling like domain localization (ENSRF/EAKF) 20 20 21 The return value can be directly used, e.g. as 21 22 23 **Notes:** 24 * The function can also be used as an alternative to `PDAF_localfilter` in `assimilate_pdaf`. 25 * The return value can be directly used, e.g. as 22 26 {{{ 23 27 IF (PDAF_local_type() > 0) THEN 24 28 CALL PDAFomi_set_localize_covar(...) 25 29 }}} 26 27 **Notes:**28 * The function can also be used as an alternative to `PDAF_localfilter` in `assimilate_pdaf`.
