WMO supports Members in accessing proper technology for the generation of high-quality hydrological data and corresponding information products and services. WMO Global Hydrological Data Centres take the lead in this area. Members will benefit from further developments in the Global Hydrometry Support Facility (WMO HydroHub), the World Hydrological Cycle Observing System (WHYCOS), and the Meteorology, Climatology and Hydrology Database Management System (MCH). These are all essential for the wise management of water resources.
