WMO Hydrological Observing System (WHOS)
The WMO Hydrological Observing System (WHOS) facilitates interoperable hydrological data sharing. It is a multi-scale (local, national, regional and global) solution using different tools which also provides registry of hydrological data and information services, catalogued using the open standards and procedures developed by the Open Geospatial Consortium (OGC), the WMO, W3C, GeoJson, and other relevant organizations.
WHOS is being developed and implemented in two phases:
- Phase 1 provides a map interface with links to those National Meteorological and Hydrological Services (NMHSs) that make their real-time and historical hydrological data available online.
- Phase 2 provides a services-oriented framework linking hydrological data providers and users through a hydrological information system of systems enabling data registration, data discovery and data access.
Regional and national WHOS prototypes located in the La Plata Basin in South America (WHOS-Plata) and in the Arctic Region (WHOS-Arctic) have reached their final stage of implementation.

WHOS-Arctic Portal
WHOS-Arctic Portal provides hydrometeorological data shared by Canada, Finland, Denmark (for Greenland), Iceland, Norway, Russia and the United States of America for the Arctic-HYCOS Basic Network of Hydrological Stations (BNHS). WHOS-Arctic Portal is implemented using ArcGIS Online for the map interface and USGS GWIS (Graphing Water Information System) for the time-series plots.
WHOS-Plata Portal
WHOS-Plata Portal provides hydrometeorological data collected in the La Plata river basin and shared by Argentina, Bolivia, Brazil, Paraguay and Uruguay. WHOS-Plata Portal is implemented using the Water Data Explorer application.
WHOS-Global Portal
WHOS-Global Portal provides all hydrometeorological data shared through WHOS. WHOS-Global Portal is implemented using the Water Data Explorer application.
