+This page documents the routine `PDAFomi_set_localization_noniso` of PDAF-OMI.
+
+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.
+
+This routine is for non-isotropic localization (for non-isotropic localization see [wiki:PDAFomi_set_localization])
+
+The routine has 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_set_localization_noniso(thisobs_l, nradii, cradius, sradius, locweight, locweight_v)
+
+    TYPE(obs_l), INTENT(inout) :: thisobs_l  ! Data type with local observation
+    INTEGER, INTENT(in) :: nradii            ! Number of radii to consider for localization
+    REAL, INTENT(in) :: cradius(nradii)      ! Localization cut-off radius
+    REAL, INTENT(in) :: sradius(nradii)      ! Support radius of localization function
+    INTEGER, INTENT(in) :: locweight         ! Type of localization function
+    INTEGER, INTENT(in) :: locweight_v       ! Type of localization function in vertical direction (only for nradii=3)
+}}}
+
+'''Notes:'''
+ * The arguments are usually the same inputs as used when calling `PDAFomi_init_dim_obs_l` for non-isotropic localization
+ * `locweight_v` is only taken into account for 2+1D factorized localization
