1. Global Terrestrial Networks : The Hydrological Network

2. Global Terrestrial Network - Hydrology Findings of the Second Adequacy Report of GCOS ▌It is urgent to address the inadequacies of the hydrological network and in particular the timely exchange of data. (First Adequacy Report November 1998) ….. ▌Progress in completing the global database has been distressingly limited ▌There is decline in the terrestrial observational network especially the hydrologic network ▌In spite of repeated calls by the international community for free and unrestricted exchange of hydrological data, this still does not take place. ▌….

4. GTN-H Status October 2008

5. Global Terrestrial Network - Hydrology 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

6. Global Terrestrial Network - Hydrology 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

16. Data Exchange

17. Global Terrestrial Network - Hydrology WMO Resolutions ▌Res. 40 (Cg-XII)-WMO policy and practice for the exchange of meteorological and related data and products. ▌“Members shall provide on a free and unrestricted basis essential data and products which are necessary for the provision of services in support of the protection of life and property and the well being of all the nations…” ▌Res 25 (Cg-XIII) -Exchange of hydrological data and products. ▌“Members shall provide on a free and unrestricted basis those hydrological data and products which are necessary for the provision of services in support of the protection of life and property and the well being of all the nations…”

18. Global Terrestrial Network - Hydrology Survey on Data Exchange ▌39% no requirement for exchange of data and products; ▌59% dissatisfied with the exchange at the international level; ▌47% place restrictions on international exchange; ▌Mostly non-on-real time or historical data. ▌20% provide flood forecasts, ice jams or alerts on water quality or pollution events.

19. Global Terrestrial Network - Hydrology WHYCOS and Data Exchange ▌Countries are the owners of the data they generate ▌NHSs are responsible for data validation ▌Agreement to share data and information within HYCOS project ▌Establishment of Hydrological Information Systems ▌Access to data using Internet and other data transmission technologies ▌Cooperation with international data centres and programmes (GRDC, GPCC)

20. Global Terrestrial Network - Hydrology Regional Hydrologic Information Systems ▌Enhance existing field data collection systems and installation of new facilities where necessary ▌Upgrade national data processing, rescue and archiving systems. ▌Establishment of a regional data and information base ▌Establishment of a Regional Telecommunication Network (RTN) on flood-related information ▌Preparation and dissemination of hydrological information of national and regional interest

21. Global Terrestrial Network - Hydrology Hydrological Applications and Run-Off Network (HARON) Project Implementation ▌Phase 1: Upgrade & sustained maintenance of major global run-off stations, monitoring continental freshwater fluxes into the world’s oceans ▌Phase 2: Integration of hydro-meteorological and related in-situ components with satellite observations ▌Phase 3: Consolidation of integrated hydrological observation network development and application of user-oriented information products made available by HARON

22. Global Terrestrial Network - Hydrology Seek support of GCOS SC through: Seek support of GCOS SC through:  Expressing support to continued advancing of GTN-H and its contributing networks;  Stressing the importance of global hydrological networks, including efficient data exchange ;  Promoting the implementation of the HARON project as a WIGOS pilot project in collaboration with GEO;  Reiterating the strong concern over the continuing decline of hydrological networks, especially the closure of climate-relevant stations;  UNFCCC, calling upon Members to assign highest priority to strengthening hydrological observation networks
