    20 After the initialization of the parallelization for the assimilation program, the initialization of PDAF has to be implemented. Internally to PDAF, the initialization is performed by the routine `PDAF_init`. Typically, we collect the initialization of all variables required for the call to `PDAF_init`  into a single subroutine, which yields a clean code In the example in `tutorial/offline_2D_serial` the routine in the file `init_pdaf_offline.F90` shows this strategy. The file `init_pdaf.F90` in `templates/offline_omi` provides a commented template for this routine, which can be used as the basis of the implementation.
     20The PDAF release provides example code for the offline mode in `tutorial/offline_2D_parallel`. We refer to this code to use it as a basis.

    2224`PDAF_init` itself calls a user-supplied routine to initialize the ensemble of model states through its interface. In the example, this is the routine in the file `init_ens_offline.F90`.
