    1010In the online mode of PDAF one couples PDAF to a model into a single assimilation program. With version 1.16 we introduced PDAF-OMI, the [wiki:PDAF_OMI_Overview Observation Module Infrastructure]. The tutorials are adapted for OMI, while tutorials describing the implementation without OMI are provided further below. The implementation is done from the templates provided in /templates/online of the source code package. Two implementations are demonstrated: The case that the model itself is not parallelized and the case that the model is parallelized (i.e. if field is decomposed over several processes).

    1818In the offline mode of PDAF one uses separate programs for the model and the data assimilation. The implementation is done from the templates provided in /templates/offline of the source code package. The tutorial describes the implementation with PDAF-OMI that was introduced with version 1.16.

    3131With PDAF version 1.16 we introduced PDAF-OMI (Observation Module Infrastructure). We recommend to use this new way to implement observationhandling more efficiently. However, implementing without OMI is still possible and here we provide the tutorial slides for this case:
