| 3 | 5 | After the adaption of the parallelization, the initialization of PDAF has to be implemented. Typically, all initializations of variables required before the call to the initialization routine PDAF_init can be colledted into a single subroutine. The example implementation uses the routine init_pdaf. The right place to insert this routine to the model code is in between the initialization part of the model and its time stepping loop. In the routine a number of variables have to be defined. The are, for example the size of the ensemble and the type of filter algorithm. The example implementation explains the full set of variables. The example also initializes a few variables that are not handed over to PDAF_init, like delt_obs. This variable is the number of time steps between sucessive analysis steps. It is meaningful to define it at this central position. Of course, this definition has to be adapted to the particluar model used. |
