Presentation Transcript

  1. Global Terrestrial NetworkHYDROLOGY (GTN-H)

  2. About GTN-H • Links existing networks and systems for integrated observations of the global water cycle • Established in 2001 • “network of networks” for global and regional climate and water applications

  3. Goals of GTN-H • Aims at creating a global hydrological network of networks • Plans and implements projects that facilitate access to hydrological networks and observation data, and generates derived products • Forms an essential component for integrated global and regional hydrological products

  4. 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

  5. International Context Joint effort of the: • World Meteorological Organization/Climate and Water Department (WMO/CLW) • Global Climate Observing System (GCOS) • Global Terrestrial Observing System (GTOS) • Observational arm of the Group on Earth Observations/ Integrated Global Water Cycle Observations Theme (GEO/IGWCO)

  6. Selected Achievements • Prototype system for the online near-real time data access to over 400 river gauging stations worldwide • Access to a first global gridded precipitation product • First-time online access to a global water quality database • Prototype definition of a hydrological metadata standard, based on the WMO core metadata standard

  7. Current Network Partners

  8. Configuration (as of November 2009)

  9. Results of the 4th GTN-H Coordination Panel MeetingNew York, 7-10 July 2009 • Improve communication and funding, • Data integration and product development, • Development of demonstration projects intended to highlight the importance of hydrological, hydrometeorological and related observations in various application areas, • Aiming to demonstrate relevance of GTN-H in underpinning adaptation decisions related to climate variability and change and global environmental challenges.

  10. GTN-H Planning Workshop preceding the GTN-H Coordination Panel Meeting • Presenting key examples of progress in the technical, scientific and applications realms that have developed or are using GTN-H relevant data resources, • Recognizing and integrating data provider, data user, and data synthesis perspectives, • Developing an initial vision of short (0-2 year), medium (2-5 year), and longer term (> 5 year) progress.

  11. GTN-H Actions 1 (selected)

  12. GTN-H Actions 2 (selected)

  13. Request to GTOS • Review the validity of the Global Hierarchical Observing Strategy (GHOST): (http://www.fao.org/gtos/GHOST.html) and propose conceptual and practical ways to integrate with GTN-H observations; • Participate more actively in GTN-H activities including through the joint development of relevant products
