Services for Hydrology

WMO is the lead United Nations specialized agency for operational hydrology, which covers the entire value cycle related to inland waters. This includes real-time and regular measurement, collection, processing, archiving and distribution of hydrological, hydrometeorological and cryospheric data to hydrological services, the development of analyses, models, forecasts and warnings to inform society, governments, disaster agencies, water resources management and support all water-related decisions.
