The WMO Information System (WIS)
The WMO Information System (WIS) is an overarching approach to meet information exchange requirements of all WMO Programmes. It will help WMO to avoid data incompatibilities, and problems in the sharing of valuable data between various programmes. It will ensure interoperability of Information Systems between WMO Programmes and outside of the WMO community.
The WMO Information system (WIS) is the pillar of the WMO strategy for managing and moving weather, water and climate information in the 21st century. WIS provides an integrated approach suitable for all WMO Programmes to meet the requirements for routine collection and automated dissemination of observed data and products, as well as data discovery, access and retrieval services for all weather, climate, water and related data produced by centres and Member countries in the framework of any WMO Programme.
Three functional components are defined:
National Centres (NC)
Data Collection or Product Centres (DCPC)
Global Information System Centres (GISC)
