  1. GTS as WIS Component Kevin Alder RA V Coordinator of the Subgroup on Regional Aspects of ISS Member, ET on WIS-GTS CTS Meteorological Service of New Zealand Limited

  2. Contents • Function of the GTS • Organisation of the GTS • Design Principles • Governance • Implementation • WIS Services • WIS Implementation

  3. Function of the GTS • to facilitate the flow of data and processed products to meet WWW requirements in a timely and cost-effective way, ensuring that all members have access to data and products in accordance with approved procedures and within agreed limits of the WWW system • It also gives telecommunications support to other programmes, as decided by the WMO Congress or the Executive Council, within the limits of its primary objectives.

  4. Executive Council “…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.”

  5. Organisation • The GTS shall be so organised as to accommodate the volume of information and its transmission within required time limits to meet the needs of World, Regional Specialised and National Meteorological Centres • Main telecommunication network linking together WMCs and designated RTHs • Regional telecommunication networks • National networks

  6. Six Design Principles • For the collection, exchange and distribution of information on a world-wide basis to meet the needs of all NMS as well as WMCs and RSMCs within the agreed WWW system • An integrated network with point to point, point to multi-point and multi-point to point circuits • Circuits are adequate to accommodate the volume of information exchanged • Designed to ensure the highest practicable reliability and availability • Will connect NMCs, RSMCs, RTHs, and WMCs • Diversity provided through alternative routing

  7. GTS Governance • The GTS includes mechanisms to facilitate information management and information exchange, in response to changing requirements • How communication links are implemented with a Region is the responsibility of that Regional Association • Governance includes data management, quality controls, deployment of new technologies and real-time and non real-time monitoring

  8. GTS Implementation • Point to point circuits operating over leased lines • Point to multi-point circuits operating over satellite e.g. EMWIN in RA IV and RA V RA-IV RMTN over ISCS MDD in RA I DAB in RA II • Managed Data Networks e.g. RMTN RA VI and most of the MTN • Internet

  9. Current situation: GTS WWW GTS Regional/Specialized Meteorological Centres Meteorological and R&D Satellite Operator Centres World Meteorological Centres National MeteorologicalCentres Information management agreed data formats; implicit metadata; catalogues Information exchange agreed procedures; real-time

  10. Current situation (GTS + other WMO programmes 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”

WIS DCPC NC NC NC/ DCPC Managed, Regional and Internet NC NC/DCPC Communication Networks NC GISC NC GISC GISC NC DCPC DCPC GISC GISC Satellite Dissemination NC NC SatelliteTwo-Way System NC NC On-demand “pull” Information exchange Common procedures; real-time, non-real time Information management a few standard data formats; coordinated 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 Commercial Service Providers WMO World Data Centres internet Real-time “push”

  12. WIS Services (1) Routine collection and dissemination service for time-critical and operation-critical data and products: Based on real-time “push” mechanism (including 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;

  13. WIS Services (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

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

  15. WIS DATA-COMMUNICATIONS FUNCTIONS AND SERVICES(weather, water, climate and related data and products) Essentially through telecom. with guaranteed quality of service, e.g. leased circuits, dedicated data com network services, sat.-based systems, .. Essentially through satellite based data distribution systems, e.g. DVB-S IGDDS GTS Data pull Data push DAR Essentially through the Internet(HTTP, FTP, VPN…) WIS 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

  16. WIS Implementation Phase A Is the continued consolidation and further improvements of the GTS for time-critical and operation-critical data, including its extension to meet operational requirements of WMO programmes in addition to World Weather Watch (including improved management of services)

  17. WIS Implementation Phase B Would provide for an extension of the information services through flexible data discovery, access and retrieval services to all users, as well as flexible timely delivery services (target for the GISC-DCPC prototype demonstrations)

  18. WIS Implementation IGDDS - WMO Space Programme The current development of IGDDS as a component of the WIS will focus on the exchange of space-based observation data and products contributes to phase A and B.
