14 TRENDS IN INFORMATION TECHNOLOGIES
Exponential growth of the Internet - including global penetration Source: Internet Software Consortium (http://www.isc.org/) , 2003 WMO Metadata Workshop 27.September.2005

15 TRENDS IN INFORMATION TECHNOLOGY
The opportunity is to take these new technologies and build a logically separate Future WMO Information System (FWIS), using the Internet, which meets the requirements of all WMO programmes for the exchange of meteorological and related data. Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

16 WMO Congress XIV (2003) “The multiplicity of systems of the different Programmes causes incompatibilities, inefficiencies, duplication of efforts and higher overall costs.” Congress approved the concept of FWIS, which will provide a single coordinated global infrastructure for the collection and sharing of information in support of all WMO and related international programmes. Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

17 Inter-Programme Task Team on FWIS
Created in 1998 by CBS-Ext(98), Karlsruhe (Germany) Melbourne (Australia), 1-5 Nov. 1999 Monterey, CA (USA), 28 Aug. - 1 Sep.2000 Langen (Germany), Jun. 2001 Johannesburg (South Africa), Sep. 2002 Kuala Lumpur (Malaysia), Oct. 2003 Geneva (Switzerland), Sep. 2004 Result: Concept, pilot projects Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

18 Cross-programme requirements for FWIS
Widely available and electronic (on-line) metadata and data catalogues of all relevant data required by the WMO Programmes Harmonisation of data formats, transmission standards, archiving and distribution mechanisms to better support inter-disciplinary use of data and products. Standard practices for the collection, electronic archival and exchange of metadata, both high-level and detailed, especially for stations and instruments. Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

19 Technical requirements
Routine collection and automated dissemination of all observed data and products (”push”) according to requirements. Ad-hoc requests for data and products (”pull”) FWIS should be reliable, cost-effective, modular, scalable, and flexible to support: Different user groups Various data policies, such as WMO Res. 40 and 25 Data as well as network security Integration of diverse datasets Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

20 Virtual structure of FWIS
National Centres (NC) Global Information System Centres (GISC) Data Collection and Production Centres (DCPC) Data communication network The names of these virtual centres describe their functionality, not the actual organisational entities. There may be organisations, such as NMHSs, which combine all three virtual centres within one facility. Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

21 National Centre (NC) Collect national observations
“Push” data intended for global dissemination to the associated GISC “Push” data intended for regional or specialised distribution to the associated DCPC Collect, generate and disseminate products for national use. Participate in monitoring the performance of the system Authorize their national users to access FWIS, as appropriate Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

22 Global Information System Centre (GISC)
Receive observations intended for global exchange from NCs and DCPCs within their area of responsibility Exchange information intended for global exchange with other GISCs Disseminate, within its area of responsibility, the data and products agreed by WMO for global exchange Hold the data and products agreed for 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 Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

23 Data Collection and 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 Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

24 Data communication network
The data communication network should: be based on an agreed technology available to the participating centres be capable of handling the data volumes include satellite communication channels, terrestrial links and managed data network services handle the agreed transmission protocols Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

25 Information collection data flow

26 Information distribution
Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

27 New features Common to all WMO programmes
Supporting real and non-real time data sets Supporting “pull” and “push” mechanisms for all data Supporting various communication protocols for data transmission Using different types of communication links as available and appropriate, including GTS, satellites and Internet Using off-the-shelf hardware and software systems Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

30 Impact on and benefits for WMO
FWIS concerns only telecommunication and data management functions of the WMO and does not affect the data processing components of any WMO Programme. Provision of data and products on the basis of request/reply services would likely be the most significant addition. Programmes would benefit from the services offered by FWIS for the implementation of their data exchange tasks. For individual users, either a person or an institution, FWIS would 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. By making use of off the shelf technologies of a lower cost, FWIS would allow least developed Members, for the first time, to actively participate in the WMO Programmes, specifically the WWW. Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

31 How could FWIS be constructed?
A GISC is a new development (metadata directories, etc.) The NC and DCPC basically already exist and add interfaces for new services A pilot project for GISC development is the RA-VI VGISC project Development of more GISC’s projects, e.g. RA-II project Workshop in conjunction with CBS-Ext(06) Trials of inter-GISC communication after 2006 Phased implementation of FWIS from 2008 onwards Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

32 RA-VI VGISC Project In 2001, RA-VI decided to create a project for the development of a prototype GISC. The NMSs of France, Germany and the UK have volunteered to jointly design and implement a virtual GISC (VGISC) shared by their Services and to include the ECMWF and EUMETSAT as DCPCs into the concept, funded partially as EU project SIMDAT. A proof-of-concept system was demonstrated during CBS XIII. Dieter C. Schiessl, WMO, Feb 2004 WMO Metadata Workshop 27.September.2005

49 Inter-Commission Coordination Group on FWIS (ICG-FWIS)
Created in 2004 by EC-LVI through Resolution 2. Terms of reference: To coordinate the refinement and consolidation of the FWIS based on the approved concept and then the implementation planning phases; To assess in detail the data exchange and data management requirements of WMO Programmes, at present and for the foreseeable future, which should be met by the FWIS; To advise the technical commissions on the development in data-communications and management functions to be required in the FWIS as regards their respective programmes; To guide the orderly evolution of existing WMO information systems towards FWIS; To address the major issues that had been identified. WMO Metadata Workshop 27.September.2005

50 Inter-Commission Coordination Group on FWIS
ICG-FWIS (First meeting in Geneva, January 2005) recommended coordination mechanisms for the FWIS development and future activities: Support of the proposed CBS Inter-Programme Expert Team on Metadata Implementation, Expert Team on FWIS GISCs and DCPCs and Expert Team on FWIS/GTS Communication Techniques and Structure. Strongly supported the establishment of TCs’ Expert Teams that are relevant to FWIS (data-management, metadata, XML, data-exchange) and their mutual cooperation and coordination for fostering consistent and rapid FWIS development Metadata aspects are crucial for the FWIS development and should be quickly consolidated, full endorsement of the WMO Core Profile of the ISO Metadata Standard. Recommendation for organizing a inter-programme workshop on metadata, jointly with CBS/IPET-Metadata, by September 2005 and a workshop on GISC development, jointly with CBS/ET-GISC&DCPC (1 Q 2006) Importance of the development of new Programme’s pilot projects to promote an early introduction of FWIS elements Recommendation to rename FWIS as WIS (WMO Information System) WMO Metadata Workshop 27.September.2005

51 Summary The WIS would be used for the collection and sharing of information for all WMO and related international programmes. The WIS vision provides a common roadmap to guide the orderly evolution of the information system functions performed by current WMO Programmes into an integrated system that meets efficiently all of the requirements of Members for the relevant international environmental information. The support and involvement of regional associations and technical commissions is needed, as early as possible, in all phases of the WIS development in order to ensure a full and shared ownership of the project, and its effective implementation. There should be a workshop on WIS in conjunction with CBS-Ext(06) The implementation of WIS needs to be done in a phased approach in order to support the IPY (International Polar Year 2007/2008) and THORPEX.
