CEOS IDN: International Directory of Earth Observation Datasets

The Committee on Earth Observation Satellites (CEOS) International Directory Portal is an international effort to help researchers locate information on available Earth science datasets and services. It is sponsored by the National Aeronautics and Space Administration (NASA) as a service to the Earth science community. The directory's metadata was last updated on March 5, 2026.

Use Cases

• Discover satellite datasets for climate monitoring based on the described coverage of climate indicators.
• Locate geospatial data services for land surface analysis based on the described Earth science scope.
• Identify remote sensing data sources for oceanographic research based on the described coverage of oceans.
• Find atmospheric data for modeling based on the described coverage of the atmosphere.

Strengths

• Sponsored and maintained by the National Aeronautics and Space Administration, indicating an authoritative source.
• Covers a broad range of Earth science domains as indicated by platform tags, including atmosphere, oceans, and land surface.
• Metadata record was last updated on March 5, 2026, suggesting recent maintenance.

Limitations

• Description metadata is limited; actual data quality and accessibility require manual inspection after navigating the portal.
• The specific number of datasets, their formats beyond HTML, and detailed row/column structures are unknown.
• Column-level documentation is absent; field semantics and data structure must be inferred after accessing individual dataset entries.
