• EUMETSAT will implement a pilot WIS 2.0 node during the latter part of 2023. This will make a selection of core data available via the global broker and global cache.
•  EUMETSAT will also implement a full WIS 2.0 node in 2024. We will add data streams incrementally to the operational WIS 2.0 node during 2024 and 2025.
•  By the end of 2025, all GTS traffic to EUMETSAT should be migrated to equivalent WIS 2.0 subscriptions, and all data currently provided by EUMETSAT via the GTS should be available via WIS 2.0. In addition, examples of novel core data and recommended data should be available via WIS 2.0.
