-For the analysis step of the ETKF, different operations related to the observations are needed. These operations are requested by PDAF by calling user-supplied routines. Intentionally, the operations are split into separate routines in order to keep the operations rather elementary. This procedure should simplify the implementation. The names of the required routines are specified in the call to the routine `PDAF_put_state_etkf` that was discussed before. With regard to the parallelization, all these routines are executed by the filter processes (`filterpe=1`) only.

 For completeness we discuss here all user-supplied routines that are specified in the interface to PDAF_put_state_etkf. Thus, some of the user-supplied routines that are explained on the page explaining the modification of the model code for the ensemble integration are repeated here.
