  1. WMO Information System (WIS)Managing & Moving Weather, Water and Climate Informationin the 21st Century WORLD METEOROLOGICAL ORGANIZATION Weather – Climate - Water José Arimatéa de Sousa Brito Information and Telecommunication Services Division Observing and Information Systems Department World Meteorological Organization

  2. WMO Information System (WIS)DESIGNING AND IMPLEMENTING WIS • Overview • Background information • Project plan • Objectives and vision • Scope of the project • Organizational structure • Project implementation • User requirements (RRR) • Technical specifications • Governance procedures • WIS guidelines (WIS Manual) • ET-CTS critical issues • Engagement of ET-CTS World Meteorological Organization

  3. IMPORTANT QUESTIONS • What is the WMO Information System (WIS)? • Why is it being developed? • What services will it provide? • What will the NMHS gain from WIS? • What is the overall WIS plan? • How far has its implementation progressed? • What are the major challenges still to be met? World Meteorological Organization

  4. WMO INFORMATION SYSTEM Direction from WMO Congress (2003) • Develop: • Over-arching approach for solving data management problems for all WMO and related international programmes • A single, coordinated global infrastructure, the WMO Information System (WIS) for the collection and sharing of information World Meteorological Organization

  5. REASONS FOR WIS • Various WMO Programmes developing information systems independently • Incompatibilities, inefficiencies, duplication of effort and higher overall costs • Continued systems development in an uncoordinated manner would: • Exacerbate these problems • Increase difficulty in sharing information between programmes • Further isolate WMO Programmes from each other and from wider environmental community World Meteorological Organization

  6. Current situation: GTS For WWW • GTS provides: • Information collection and distribution • Real-time push for WWW data & products (and some other programmes data) • Information management • Standard data formats • Implicit metadata & catalogs World Meteorological Organization

  7. Current situation: GTS and Other WMO Programmes systems • Information exchange • Multiplicity of procedures • Real-time and non-real-time • Very limited pull • Information management • Multiplicity of data formats • Uncoordinated/lack of metadata & catalogs • No discovery World Meteorological Organization

  8. Current situation: GTS WWW GTS Regional/Specialized Meteorological Centres Meteorological and R&D Satellite Operator Centres World Meteorological Centres National MeteorologicalCentres interconnects World Meteorological Organization

  9. WIS Vision • Integrated approach for all WMO Programmes • Routine collection and dissemination of time-critical and operation-critical data and products: • Real-time “push”through dedicated telecommunication • Data Discovery, Access and Retrieval service: • “Pull” through the Internet (HTTP, FTP,…) • Timely delivery of data and products: • Delayed mode “push” through dedicated telecommunication means and public data networks, especially the Internet • Unified procedures • More efficient data exchange • Coordinated and standardized metadata • Interoperability between programmes • Improved data management • ISO 191xxx series for geographic information World Meteorological Organization

  10. WIS brings new features and opportunities • Common information exchange standards, functions and services forall WMO programmes • Inter-disciplinarydiscovery, retrieval and exchange of information in real-time and non-real time • Inter-operability through on-line catalogues usingmetadata based on ISO 19100(geographic information standard) • Industry standards and off-the-shelf hardware and software systems to ensurecost-effectiveness and compatibility World Meteorological Organization

  12. Data pull Data push WIS DATA-COMMUNICATIONS IMPLEMENTATION(for weather, water, climate and related data and products) DAR Essentially through the Internet(HTTP, FTP, VPN…) Essentially through telecom. with guaranteed quality of service, e.g. leased circuits, dedicated data com network services, sat.-based systems, .. WIS Essentially through satellite based data distribution systems, e.g. DVB-S IGDDS GTS WIS/GTS: for time and operation-critical data & products WIS/IGDDS: for space-based data & products WIS/DAR: data discovery, access and retrieval Data push: routine distribution of data & products Data pull: access to and retrieval of data & products World Meteorological Organization

  13. Questionnaire Responses, Meeting Reports, interviews, etc Requirements Assessment Phase Assessment of Requirements (WIS Project Office – interim measure) User Reqmts Doc, WIGOS Obs db + TBD db Review of Requirements (New ET on User Requirements - to be formed) RRR Phase Consolidated and Endorsed User Requirements Determine Optimal Way to Meet User Requirements WG-PIW | ET-OI | ET-CTS Consolidation of Views (New ET on User Requirements) Process for Establishing, Maintaining and Implementing User Requirements Ad Hoc Requests for WIS Services WIS DCPC and GISC Nominations Implementation of Services Addressing User Requirements Member States (CIO) Designation of GISCs and DCPCs EC, TCs, RAs, Member States Decisions on Implementation of formal and Ad Hoc Requests Decisions on WIS Components World Meteorological Organization

  14. WIS, a key issue: interoperability • Interoperability enables the discovery, the retrieval and the usage of the data • It needs the development and the implementation of relevant Metadata standards • Development of a WMO Metadata Profileof the ISO 191xx series for geographic information • Step 1: development of the WMO Metadata Core Profile of ISO 19115 for data discovery • Step 2: Use of the ISO 191xx series for the access and use of the data World Meteorological Organization

  25. WIS SERVICES WIS provide three types of services to meet the different requirements: (1) Routine collection and dissemination service for time-critical and operation-critical data and products: Based on real-time “push” mechanism (incl. Multicast); implemented essentially through dedicated telecommunication means with guaranteed quality of service, e.g. leased circuits, dedicated data communication network services and satellite-based data-distribution systems; (2) Data Discovery, Access and Retrieval service: Based on request/reply “pull” mechanism with relevant data management functions; implemented essentially through the Internet (HTTP, FTP,…); (3) Timely delivery service for data and products: Based on delayed mode “push” mechanism; implemented through a combination of dedicated telecommunication means and of public data networks, especially the Internet. World Meteorological Organization

  26. Key Future Milestones • Consolidate plans on development, governance and implementation of WIS: 2007-2008 • Develop WIS regulatory documentation and guidance material for implementation, including specifications for the GISC interfaces and a unified user interface: 2007-2008 • Develop scheme and practices for security, authentication and authorization procedures for WIS services : 2007-2008 • Implementation of first operational GISC: 2008 • Implementation of other operational GISCs: 2009 - 2011 • Implementation of DCPCs, i.e. WIS interfaces at WMO programmes’ centres: 2008-2011 World Meteorological Organization

  27. WIS Project Gantt Chart World Meteorological Organization

  28. CRITICAL ISSUES FOR WIS • Data exchange/synchronization between GISCs • Metadata Exchange/synchronization • GISC performance standards, monitoring, storage • Two (2) minutes for warning distribution • Ten (10) minutes for other info • Holding 24 hours of information • Manual on WIS, equivalent of Manual on the GTS. • Defining steps to be taken to evolve the GTS towards WIS World Meteorological Organization

  29. EVOLUTION OF THE GTS TOWARDS WIS GENERAL PRINCIPLES • WIS has to perform better than the current GTS in any stage • Use of technology available now • Take into account current changes in Regional Networks • WIS to be cost-effective in the long run World Meteorological Organization
