Future WMO Information System (FWIS) Hiroyuki Ichijo (Japan Meteorological Agency) WMO/WSIS Session on Reducing Natural Disaster Risk through Technical Opportunities of Information Society -Applications of ICT in Natural Disaster Risk Reduction (Kobe, Japan, 21 January 2004) Introduction There are various WMO programmes. Each programme has traditionally worked independently with each information system. Argo Maritime Safety Pollution response However the needs of a coordinated common system rapidly expanded because of demerits of system multiplicity and emerging new crosscutting programmes. Furthermore evolving technology accelerated the needs. On the background, the innovative FWIS project was born in 1999. 1. Vision The Future WMO Information System (FWIS) will be a single coordinated global infrastructure for collecting and sharing information to support all WMO and related international programmes. The FWIS will meet information exchange requirements of all WMO programmes without information incompatibilities, inefficiencies, duplication of effort, limitation in sharing valuable information and higher overall costs. The FWIS will provide a flexible and extensible structure that allows National Meteorological or Hydrological Services (NMHSs) to enhance their capabilities as their national and international responsibilities grow. 2. Roadmap With the latest breakthroughs in Information Communication Technology (ICT), the FWIS concept has been developed. The concept provides a common roadmap to guide the orderly evolution of the information system functions performed by current WMO Programmes into an integrated system. Currently various pilot projects on promising technologies with prototype evaluation are under progress towards early implementation. Renaming from “FWIS” to “ WIS (WMO Information System)” is expected. FWIS WIS Implementation Pilot Projects Concept 3. Main challenges Interoperability of information systems Providing online catalogue and metadata of all information Standardization/Harmonization of information formats Providing functions to discover and share information in distributed information sources Supporting real-time, quasi real-time and non-real-time information exchange Smooth and coordinated transition Building upon the most successful components of existing WMO systems Scalable and sustainable system Supporting various standard communication protocols and links Using international industry standards and off-the-shelf hardware and software systems 4.

Internet VPN : Virtual Private Network (VPN) over the Internet Access with authentication Internet Internet VPN (IPsec) Internet VPN provides cost-effective connectivity with moderate security. Satellite-based telecommunications VSAT (Very Small Aperture Terminal) DVB (Digital Video Broadcast) DAB (Digital Audio Broadcast) One Way VSAT system is used for broadcast/multicast. Two Way VSAT system is used for combination broadcast/multicast and peer-to-peer communications.

Benefits of FWIS Information management Information exchange/access • Expanding of provision and use of potential information • Collaboration between programmes • Meeting requirements on timeliness (timecritical), reliability, and traffic volume. For NMHSs (and national disaster prevention authorities linked with NMHSs) • Improvement of information discovery and availability • Easy handling of standardized information • Strengthening mission-critical exchange (e.g. WWW operation. and distribution of emergency information) • Consolidation of exchange procedures For authorized users (e.g. academic and research communities) • Improvement of information discovery and availability • Easy handling of standardized information For WMO programmes • Flexibility in communication options • Simple access procedures Security • Coordinated full security under FWIS security policy • Coordinated full security under FWIS and/or national security policies • Appropriate security mechanism under security policies of FWIS and/or each information source Cost aspect • Great cost benefit • Reducing development cost and human resources • Further costeffective operation with saving recurrent costs • Reducing development cost and human resources • Availability of convenient services for minimum costs
