1. GTN-H Development since July 2005 Overall Objectives GTN-H Aims at a global hydrological network of networks Aims at a global hydrological network of networks Runs projects that establish and facilitate access to hydrological networks, data and products Runs projects that establish and facilitate access to hydrological networks, data and products Forms a building block for integrated global products for climate and water (WMO, GCOS, IGOS-OGWCO, GEO) Forms a building block for integrated global products for climate and water (WMO, GCOS, IGOS-OGWCO, GEO)

2. GTN-H Development since July 2005 Progress in some projects including metadata standard, gridded global runoff, Progress in development of network partners in particular with regard to the global database on lakes and reservoirs, promiding progress in defining a database host for soil moisture Progress in the development of a near rea-time global hydrological applicatons and runoff project (HARON) Prototype system an of on-line hydrological information system Access to the « First Guess » global gridded precipitation of GPCC and a 50 year climatology

3. GTN-H Development since July 2005 First-time on-line access to the global water quality data base of GEMS-Water Start-up of a « pristine basin » network in cooperaiton with WMO/CHy and WCP-Water (cross- cutting) Recognition of GTN-H in various programmes including WMO and GCOS as « parents », IGOS- IGWCO, GEO, GEWEX, and climate relevant programmes and intergovernmental bodies Establishment of a dedicated web page and online data inventory Negative development: No regular coordination of GTN-H since December 2005
