Plans
The WMO World Weather Information Service (WWIS) JSON API and the WIS2 Global Discovery Catalogue are openly accessible without any API key or registration. WWIS city weather and climatological data is free to use with attribution. The WIS2 Global Discovery Catalogue supports unauthenticated read-only queries against the OGC API - Records endpoint.
The WMO Hydrological Observing System (WHOS) APIs require a personal access token obtained via free registration at the WHOS registration portal. There is no cost associated with registration. The token is used as a path parameter in all WHOS endpoint URLs.
OSCAR/Surface GET endpoints for station search and metadata retrieval are publicly accessible without authentication. Write operations (XML uploads for station updates) require an authorized WIGOS Focal Point account with a security token issued by WMO.
The WIS2 Global Broker MQTTS service provides public read-only access using shared credentials (username: everyone, password: everyone). Any MQTT client can subscribe to WIS2 topic hierarchy topics to receive real-time notification messages for global weather, climate, and hydrological data.
