WIS2: Wmo's Data Sharing for the 21st Century - a WMO Region IV Perspective

The WMO Information System 2.0 (WIS 2.0) is the framework for WMO data sharing in the 21st century for all WMO domains and disciplines. It will support the WMO Unified Data policy, the Global Basic Observing Network (GBON) and make international, regional, and national data sharing simple, effective, and inexpensive. Users of WIS 2.0 will be able to access data in real-time by subscribing to a Global Broker and receiving notifications when new data are available for download from a Global Cache or from the data provider. The Global Discovery Catalogue will allow users to discover the available datasets on WIS 2.0 and provide information on how and where to access the data. This paper will provide a WMO Region IV perspective on WIS2 Global Services, how the FAIR (Findable, Accessible, Interoperable and Reuseable) principles come into play, and the open standards and Web technologies used to facilitate sharing of increasing variety and volume of real-time data.
