The objectives of MiKlip's Module E are twofold; on the one hand the generation, provision, and application of new observational data products – an activity strongly supported by the DWD – and on the other hand, the development and application of process oriented validation tools for the MiKlip decadal prediction system. The coordination of this module includes ensuring communication between projects in Module E by organising regular meetings and workshops, monitor and synthesise progress, harmonisation of activities across MiKlip Modules via a constant exchange, the dissemination of results to the international scientific community, as well as bringing in insights gained in other projects on decadal prediction.
