One of the main objectives of ChEESE is to make Pilot Demonstrators available as services that can be exploited by a broader user community. To achieve this goal, we have involved the geophysical community (in coordination and synergy with other pan-European initiatives) and the non-academic stakeholders (industrial partners, observatories, civil protection authorities belonging to the IUB), in the definition of the services and their validation. In particular, the end-users have cooperated in defining the service objectives, the gaps to fill, the relevant scientific/societal questions addressed, the technological bottlenecks.

Six pilots within ChEESE have demonstrated potential service exploitation during “live” exercises, in which target use-cases have been numerically addressed and service functional requirements (e.g., required time-to-solution, spatial/temporal resolution, minimum ensemble size), tested in an operational environment. Computational resources have been pre-allocated on HPC centres on the expected time-slots.

The live exercises have addressed 53 institutions (represented by 99 individuals) from 26 different countries.
