The mission of the International Council for Science is to ensure the long-term stewardship and provision of quality-assessed data and data services to the international science community and other stakeholders. To support this goal they have developed World Data System (WDS) data portal and activity monitor.
The WDS Data Portal enables retrieval of datasets from members of the World Data System, and is searchable using both geographic and temporal coverage.
The WDS Activity Monitor is an interactive portal using the world map to capture current information about each member of the World Data System.

WDS member datasets include:

• National Climatic Data Centre
• National Geophysical Data Centre
• Space Environment Centre, National Weather Services
• NODC - National Oceanographic Data Centre
• PANGAEA - Data Publisher for Earth & Environmental Science
• World Data Centre for Climate
