1 World Meteorological Organization WMO Information System (WIS) Managing & Moving Weather, Water and Climate Information in the 21 st Century WORLD METEOROLOGICAL ORGANIZATION Weather – Climate - Water
2
2 World Meteorological Organization Overview 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?
3
3 World Meteorological Organization WMO Information System (WIS) 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
4
4 World Meteorological Organization 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

6 World Meteorological Organization GTS provides: Information collection and distribution o Real-time push for WWW data & products (and some other programmes data) Information management o Standard data formats o Implicit metadata & catalogs Current situation: GTS For WWW
7
7 World Meteorological Organization Information exchange o Multiplicity of procedures o Real-time and non-real-time o Very limited pull Information management o Multiplicity of data formats o Uncoordinated/lack of metadata & catalogs o No discovery Current situation: GTS and Other WMO Programmes systems
8
8 World Meteorological Organization I ntegrated approach for all WMO Programmes Routine collection and dissemination of time-critical and operation-critical data and products: o Real-time push through dedicated telecommunication Data Discovery, Access and Retrieval service: o Pull through the Internet (HTTP, FTP,…) Timely delivery of data and products: o Delayed mode push through dedicated telecommunication means and public data networks, especially the Internet Unified procedures o More efficient data exchange Coordinated and standardized metadata o Interoperability between programmes o Improved data management o ISO 191xxx series for geographic information WIS Vision

10 World Meteorological Organization WIS brings new features and opportunities Common information exchange standards, functions and services for all WMO programmes Inter-disciplinary discovery, retrieval and exchange of information in real-time and non-real time Inter-operability through on-line catalogues using metadata based on ISO 19100 (geographic information standard) Industry standards and off-the-shelf hardware and software systems to ensure cost-effectiveness and compatibility
11
11 World Meteorological Organization What will a NMHS gain from the WIS? 1.Improved forecasting/warning services Faster and more cost-effective exchange of operation- critical information; 2.Improved and expanded range of services Discovery and access to new data and products: oSatellite data and products, ensemble prediction products, climate predictions, oceanographic data and products, operational, and research data and products, reports, publications 3.Strengthened role as national service provider Ability to push to national users critical information: oWarnings, advisories, selected measurements, etc.; (eg: national agencies dealing in disaster mitigation, agriculture, energy and water management,) 4.Better appreciation by partner agencies Supports their pulling relevant information from WMO
12
12 World Meteorological Organization Structure of WIS Functional centres: National Centres (NC) Global Information System Centres (GISC) Data Collection and Production Centres (DCPC) and Data communication networks WIS concerns only information exchange and data management functions
13
13 World Meteorological Organization Structure of WIS Functional centres interconnected by data communication networks: National Centres (NC) –Links national data providers and users to regional and global data exchange nodes, and administrates access to WIS Data Collection and Production Centres (DCPC) –Provides for regional and international exchange of WMO programmes data and products –Supports data and information push and pull Global Information System Centres (GISC) –Provides for global exchange of data and products –Collects and provides metadata for all data and products –Supports data and information discovery and pull
14
14 World Meteorological Organization National Centre (NC) Provides information collected/generated in the country to a GISC or DCPC Serves as portal for national users and/or administrates their access to WIS Several NCs in a country are possible (not just the NMC) Data Collection or Production Centre (DCPC) Provides the programme-related data & products for international exchange Supports information Push and Pull mechanisms Generates, maintains, makes accessible and provides to GISCs metadata catalogues of its data & products
15
15 World Meteorological Organization Global Information System Centre (GISC) Receives information from NCs and DCPCs Exchanges information (data and metadata) with other GISCs Disseminates, within its area of responsibility, the entire set of WMO data and products for routine global exchange Supports information Pull mechanisms Generates, maintains and makes accessible metadata catalogues of all data and products for global echange Ensures around-the-clock, reliable and secure operations
16
16 World Meteorological Organization 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 Profile of 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 WIS, a key issue: interoperability
17
17 World Meteorological Organization 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. WIS SERVICES
18
18 World Meteorological Organization WIS DATA-COMMUNICATIONS FUNCTIONS AND SERVICES EC emphasized that with the sustained progress benefiting from Information & Communication Technology (ICT) development made in its implementation, operation and upgrade, the GTS, including satellite-based data-distribution systems and the Improved MTN, would effectively contribute to the WIS implementation as the core communication component for exchange and delivery of time and operation-critical data and products.

29 World Meteorological Organization XV Congress endorsed in principle, upon ICG-WIS and CBS recommendations, the procedures for the designation Global Information System Centres (GISC) and the Data Collection or Production Centres (DCPC). Congress encouraged Members to adhere to them until they would eventually be included in WIS regulatory documentation. WIS governance
30
30 World Meteorological Organization i) Statement of WIS requirements WMO TCs and other bodies state & review their programmes requirements for WIS services. WIS requirements and functions are compiled and regularly reviewed by ICG-WIS and reported to EC. ii) Service offers by potential GISCs and DCPCs Existing centres from WMO systems and programmes may apply for designation as GISC or DCPCs. The service offer addressed to WMO should include: - A statement of compliance with the required WIS functions - GISC: proposed area of responsibility for WIS data services - DCPC: programmes candidate DCPCs endorsed by relevant TCs - Formal commitment by the PR of the Member to implement the GISC or DCPC and provide the WIS services. ICG-WIS analyzes the proposed services versus WIS requirements and the compliance to the required WIS/GISC or DCPC functions and specifications, and formulates a recommendation. DESIGNATION PROCEDURES FOR GISCs AND DCPCs
31
31 World Meteorological Organization iii) Demonstration of GISC or DCPC capabilities Candidate GISCs and DCPCs demonstrate to CBS their capabilities to provide WIS services to accredited users with the necessary reliability and quality. Adherence to WIS standards and relevant data exchange policies and access rights must be granted. (real-time functions of data and product collection and dissemination, non real-time services for requests, storage functions, coordination / synchronization functions with GISC, up-to-date metadata catalogues). CBS formulates recommendation for the GISC and DCPC designation. iv) Designation of GISCs and DCPCs The Executive Council considers for approval the ICG-WIS recommendation and CBS recommendation for the GISC and DCPC designation Upon EC approval, the GISC or DCPC is included in the relevant WMO programme documentation. DESIGNATION PROCEDURES FOR GISCs AND DCPCs
32
32 World Meteorological Organization 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
33
33 World Meteorological Organization Challenges Good progress made in concept, technological solutions and prototypes for WIS, but much work to be done for an operational WIS Understanding of WIS – both internal and external to WMO: –What it is, why it is important, what it does for NMHSs, what needs to be done, … Active participation of WMO Technical Commissions and other bodies -- stating requirements, developing metadata and implementing WIS interface at their data centres, etc Involvement of all NMHSs in the WIS development, including awareness of users communities Adequate financial and human resources for WIS development into operations
