Global Information System Centre (GISC) Global Catalogue + 24 hour operational Global Data Cache Exchanges information & synchronises with other GISCs Receives information from NCs and DCPCs Ensures around-the-clock, reliable and secure operations maybe >1 per 2. National Centre (NC) maybe >1 per country Country collected/generated information sent to GISC/DCPC Portal for national users & administrates their access to WIS Generate standardised metadata as well as data

7. © Crown copyright Met Office 3. Data Collection & Production Centre (DCPC) Neither GISC or NC: information production facility, regional or global Generates, maintains and makes accessible standardized metadata catalogues of its data holdings through GISCs Supports information “Push” and ”Pull” mechanisms May facilitate access/exchange from/to NCs and GISCs Replaces/enhances Regional Telecom Hubs RTHs Replaces Regional Specialised Met. Centres RSMCs WIS Components - 2
