  3. Current situation (GTS + other networks) internet Regional/Specialized Meteorological Centres Meteorological and R&D Satellite Operator Centres World Meteorological Centres National MeteorologicalCentres Information exchange – multiplicity of procedures; real-time and non-real time Information management – multiplicity of data formats; uncoordinated metadata and catalogues International Organizations (IAEA, CTBTO, UNEP, FAO.. ) World Radiation Centre Regional Instrument Centres 5 GAW World Data Centres GCOS Data Centres Global Run-off Data Centre IRI and other climate research institutes Universities Regional Climate Centres stop stop stop Commercial Service Providers WWW GTS WWW GTS stop stop WMO World Data Centres stop Real-time “push” World Meteorological Organization

  5. WIS brings new features and opportunities • Common information exchange standards, functions and services for all WMO programmes • Inter-disciplinarydiscovery, retrieval and exchange of information in real and non-real time • 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 inter-operability World Meteorological Organization

  6. 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 World Meteorological Organization

  7. 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 World Meteorological Organization

  8. 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 World Meteorological Organization

  9. European Virtual GISC Project World Meteorological Organization

  10. 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

  11. WIS Implementation • Major functions needed: • Metadata catalogues • Internet portal • Data acquisition and discovery services • Data distribution service: push and pull • Monitoring • Operational aspects like data synchronisation, back-up, administrative issues, etc. • To that end, work is being undertaken by pilot projects in the different WMO Programmes World Meteorological Organization

  12. WIS DATA-COMMUNICATIONS FUNCTIONS AND SERVICES • WIS shall provide various types of services to meet the different requirements: • Routine collection and dissemination service for time-critical and operation-critical data and products • Data Discovery, Access and Retrieval service • Timely delivery service for data and products • EC “emphasized that with the sustained progress 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.” World Meteorological Organization

  13. A) The first phase of the WIS as regards time-critical and operation-critical data is in place and in operation: the GTS, under continuous upgrades and improvements. The operational data exchange service provided by the GTS, which is currently mainly focused on WWW requirements, will be extended to operational requirements of other programmes as part of the WIS; • B) This is complemented by the further upgrade and extension of WIS space component, so-called IGDDS, for satellite-data distribution; • C) The second phase, which is providing more flexible discovery and access to all users as well as more comprehensive data is the target for the GISC-DCPC demonstrations and (some) pre-operational implementation by end of this year.

Data pull Data push WIS DATA-COMMUNICATIONS FUNCTIONS AND SERVICES(for weather, water, climate and related data and products) DAR WIS 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

  15. 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

IGDDS within the WIS LEO satellites Global data (recorded/dumped) GEO satellites in the region R&D satellites Polar orbiting satellites Network of HRPT stations RARS Satellite products Local processing Local processing Local processing Central processing Central processing Regional processing GISC (Data, metadata and user management) Interoperability DCPC Data, metadata & user management Data exchange with other DCPCs Routine Dissemination Request/ reply (Internet) Request/ reply (Internet) ADM Other media National centres and other users World Meteorological Organization

  17. Several on-going pilot projects test and evaluate functional concepts and architectures • The WMO Core Metadata Standard • The Virtual (distributed) Global Information System Centre (VGISC) in RA VI, including the European SIMDAT project • RA II & V Virtual Private Network (VPN) project • The EUMETNET UNIDART project (Portal) • The JCOMM End‑to‑End Data Management Project (E2EDM) prototype • The DMAC subsystem project for IOOS • The Roshydromet CliWare project • The WAMIS project for agro-meteorological information (CAgM) • and also the Earth System GRID, the Community Data Portal, the Earth Sciences Portal • Early application of WIS to the THORPEX Interactive Grand Ensemble (TIGGE) World Meteorological Organization

  18. WIS Implementation plan – initial phase • GTS for time-critical and operation-critical exchange • Reference implementation WMO Core metadata • Integration of metadata structures into pilot GISCs and DCPCs • Internet portal • Basic data acquisition, discovery and push-pull services • RA VI VGISC project as a GISC prototype • DCPCs prototypes including the ECMWF and EUMETSAT DCPC projects associated with the VGISC project • NCAR DCPC prototype • DCPC prototype for JCOMM related data • Technical Conference on WIS (Korea, 6-8 November 2006) preceding CBS-Ext.06 World Meteorological Organization
