WMO Information System (WIS)

The WMO Information System (WIS) is a technical framework implemented by WMO Members for sharing authoritative data on weather, water, climate and environment. The WIS provides data discovery and retrieval capabilities through the Global Information System Centres (GISC) portals and enables real-time data exchange between WMO Centres through a network of data exchange systems - the Global Telecommunication System (GTS).

WIS is evolving to WIS 2.0 to support the new WMO Unified Data Policy. WIS 2.0 is the WMO data-sharing framework for the 21st century.

WIS 2.0 is up and running. WIS 2.0 Pilot Phase started in December 2022.
