WMO Peiliang Shi, Director, WIS 6 April 2011 WMO Workshop on Strategy for Implementation of CSIS Overview of the WMO Information System (WIS) WORLD METEOROLOGICAL ORGANIZATION Weather - Climate - Water
Global Observations Systems
World Meteorological Centres WWW GTS Regional/Specialized Meteorological Centres National Meteorological Centres Meteorological and R&D Satellite Operator Centres GTS current users Regional, Specialized, National and World Meteorological Centres, as well as, Meteorological Satellite Operator Centres currently exchange with the WWW GTS
WMO Information System (WIS) In 2003, the World Meteorological Congress stated that an overarching approach for solving the data management problems for all WMO and related international programmes was required: a single coordinated global infrastructure, the WMO Information System (WIS).
23 February 2014 WIS Overview5 Vision of WIS WMO Members decided that WIS will: Use international industry standards Build on the Global Telecommunication System (GTS), with a smooth and coordinated transition; Provide time-critical data exchange, as well as data access and retrieval services; Support all WMO and related international programmes.
WIS services WIS provides an integrated approach suitable for all WMO Programmes to meet the requirements of: Routine collection and automated dissemination of observed data and products (push); Timely delivery of data and products (appropriate to requirements); Ad-hoc requests for data and products (pull). Data discovery service for all data stored by any WMO programme regardless of location.
WIS users WMO programmes who will benefit from the services offered by WIS for the implementation of their data exchange tasks. NMHSs who will be able to interactively alter their operational data provisions Individual users, either a person or an institution, who will be the main beneficiary of WIS, because WIS will provide a single entry point for any data request, be it on a routine basis by dissemination of certain user defined information sets or on an ad-hoc basis for a special data set.. GEOSS because WIS is a major contributing system and an exemplar implementation of the underlying interoperability principles of GEOSS.
WIS concept Global Information System Centres (GISC) Data Collection or Production Centres (DCPC) National Centres (NC) Data communication network Only GISCs are new centres Virtual structure
WIS Centres – a three-tiered architecture to serve the users Data and Product Users Global Information System Centres (GISCs) Data Collection or Production Centres (DCPCs) National Centres (NCs)
National Centres (NC) Collect observational data from within their country Provide observations and products intended for global dissemination to their responsible GISC (possibly via a DCPC) Provide observations and products intended for regional or specialized distribution to the responsible DCPC Collect, generate and disseminate products for national use. Participate in monitoring the performance of the system Authorize their national users to access WIS, as required.
Data Collection or Production Centre (DCPC) Receive information intended for dissemination to NCs within its area of responsibility (i.e. regional collection) Collect programme-specific data and products Produce regional or specialized data and products Push information intended for global exchange to their associated GISC Disseminate information intended for regional exchange Support access to their products via request/reply (Pull) mechanism Maintain data and product catalogues in a WMO-agreed standard format and facilitate access to this catalogue
Global Information System Centre (GISC) Receive observational data and products that are intended for global exchange from NCs and DCPCs within their area of responsibility Exchange information intended for global dissemination with other GISCs Disseminate, within its area of responsibility, the entire set of data and products agreed by WMO for routine global exchange Hold the entire set of data and products agreed by WMO for routine global exchange for at least 24 hours and make it available via WMO request/reply (Pull) mechanisms Maintain, in accordance to the WMO standards, a catalogue of all data and products for global exchange and provide access to this catalogue to locate the relevant centre intended for global exchange. Coordinate the communication network within their area of responsibility X X X X X X X X X X X X X X X
Benefits of WIS In addition to improving efficiency, WIS: Enhances collection of critical data Catalogs all WMO data and products Enhances availability of time-critical data and products at all national centres Opens up GTS to other types of data Exploits technology innovation
Information request to custodian alog/arcticdata/met.no/itp37/ Search Results User searches for metadata then retrieves information from data custodian GISC – DAR service NC/DCPC information access service Centre publishes metadata to GISC DAR catalogue Security/authentication/authorization and even charging is managed by each service provider Retrieve information Search Request Sounding AND Jan Mayen
23 February 2014 WIS Overview15 Expose GTS Data via Metadata
23 February 2014 WIS Overview16 World Climate Programme (WCP) as an user of WIS Data and Product Users WIS Global Information System Centres (GISC's) World Climate Programme (WCP) WMO Information System (WIS) WIS National Centres (operated by NMHS's) Regional Climate Centers (WIS DCPC's) World Climate Data Centres (WIS DCPC's) Global Climate Forecast Producing Centres (WIS DCPC's) National Climate Data Management Systems National Climate Forecast Systems
WIS implementation status The Manual on WIS, and related amendments to WMO Technical Regulations (WMO-No.49) to be approved by Congress in 2011 The Guide to WIS endorsed by CBS in 2010 First set of GISCs and DCPCs to be designated at Congress in 2011 More DCPCs, including those in the climate service area, will be certified and designated on a yearly basis by WMO Executive Council
