1 Terrestrial Network HYDROLOGY (GTN-H) 1 GEO GTN - H GCOS IGWCO 2

2 Main Objectives Make available data from existing global hydrological observation networks and enhance their value through integration Generation of datasets suitable for: Research in the areas of global and regional climate change Environmental monitoring, and Hydrology and water resource management 3 : Observations, Models, Data and Information 4

3 WIGOS Purpose To create a specific structure (organizational, programmatic, procedural and governance) that will provide: a single focus for the operational and management functions of all s and a mechanism for interactions with co-sponsored observing systems. 5 WIGOS Benefits Enable Members to meet expanding national mandates to help them better respond to natural hazards, improve weather, water, climate and related environmental monitoring, and adapt to climate change; Enhance operational components of Programmes, especially in Developing and LDCs; Ensure essential support for the observational and information components of the future GFCS; Contribute strongly to GOOS, GTOS, GCOS and GEOSS. 6

4 WIGOS of s WIGOS must benefit society through enhanced availability and integration of global weather, climate and water observations contributed by constituent systems. WIGOS relies on a fully functional WIS not only to circulate data, but to facilitate data access and retrieval by partner organizations WIGOS and WIS working together should improve the Members capability to provide a wide range of services, by making observations easier to use through better documentation, Metadata, and quality management 7 WIGOS integration Key requirements for integration within WIGOS have now been expressed as standardization in three key areas: measurements and observations area (homogeneity, interoperability, compatibility of all observations); WIS information infrastructure (standardized set of WIS data representation and exchange requirements for all Programmes & DAR services); end-product quality management (QMS). 8

5 Instruments and methods of observation standards s for Weather, Climate, Water, Ocean, Active Quality Management WIS Standards for Data & Metadata exchange & Discovery, Access and Retrieval (DAR) Services Users QMF Standards Data Processing and Forecasting Centres Dedicated archiving Centres 9 Reasons for WIS Various Programmes developing information systems independently Incompatibilities, inefficiencies, duplication of effort and higher overall costs Continued systems development in an uncoordinated manner would: Exacerbate these problems Increase difficulty in sharing information between programmes Further isolate Programmes from each other and from wider environmental community 10

6 WIS brings new features and opportunities Common information exchange standards, functions and services for all programmes Inter-disciplinary discovery, retrieval and exchange of information in real-time and non-real time Inter-operability through on-line catalogues using metadata based on ISO (geographic information standard) Industry standards and off-the-shelf hardware and software systems to ensure cost-effectiveness and compatibility 11 Structure of WIS Functional centres interconnected by data communication networks: National Centres () Links national data providers and users to regional and global data exchange nodes, and administrates access to WIS Data Collection and Production Centres (DCPC) Provides for regional and international exchange of programmes data and products Supports data and information push and pull Information Centres (GISC) Provides for global exchange of data and products Collects and provides metadata for all data and products Supports data and information discovery and pull 12

13 WIGOS WIS contribution to GEO WIGOS-WIS implementation contributes to GEO and from there Societal Benefit Areas including IGWCO: As IGWCO s Observation component is represented by GTN-H, WIGOS-WIS has direct impact on GTN-H further development and operation. Note that GTN-H contributes directly to development of WIS in support of WIGOS! 25 WIGOS- WIS GEO GTN - H GCOS IGWCO 26
