Goals of GTN-H
• Aims at 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
The main objective of the GTN-H is to make available data from existing global hydrological observation networks and to enhance their value through integration. GTN-H thus underpins the generation of datasets suitable for:
• Research in the areas of global and regional climate change
• Environmental Monitoring
• Hydrology and water resource management
International Context: The GTN-H is a joint effort of the World Meteorological Organization / Climate and Water Department (WMO/CLW), the Global Climate Observing System (GCOS), co-sponsored by WMO, UNEP, IOC and ICSU, and represents the observational arm of the Group on Earth Observations / Integrated Global Water Cycle Observations Theme (GEO/IGWCO).
