  * As a simple case, if the localization is only performed horizontally, the local analysis domain can be single vertical columns of the model grid. In this case `n_domains_p` is simply the number of vertical columns in the local model sub-domain.
 
+=== `U_init_dim_local` (init_dim_local.F90) ===
+
+This routine is used by all local filter algorithms (LSEIK, LETKF).
+
+The interface for this routine is:
+{{{
+SUBROUTINE init_dim_local(step, domain_p, dim_l)
+
+  INTEGER, INTENT(in)  :: step        ! Current time step
+  INTEGER, INTENT(in)  :: domain_p    ! Current local analysis domain
+  INTEGER, INTENT(out) :: dim_l       ! Local state dimension
+}}}
+
+The routine is called during the loop over the local analysis domains in the analysis step. 
+It has to provide in `dim_l` the dimension of the state vector for the local analysis domain with index `domain_p`.
+
+Hints: 
+ * If a local analysis domain is a single vertical column of the model grid, the size of the state in the local analysis domain, will be just the number of vertical grid points at this location.
