Changes between Version 29 and Version 30 of ImplementAnalysisseik

v29	v30
28	28	For the analysis step of the SEIK filter 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_seik` that was discussed before. With regard to the parallelization, all these routines are executed by the filter processes (`filterpe=1`) only.

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

32	32	The SEIK filter and the ETKF (Ensemble Transform Kalman Filter) are very similar. For this reason, the interface to the user-supplied routines is almost identical. Depending on the implementation it can be possible to use identical routines for the SEIK filter and the ETKF. Differences are marked in the text below.
