Starting August 27, 2025, NSF NCAR's Climate Data Gateway (CDG) and Geoscience Data Exchange (GDEX) will be retired, and the Research Data Archive (RDA) is becoming the central home for these data collections. Please update your bookmarks and citations, and use existing DOIs or check parent dataset pages for new links to their landing pages in the RDA.

This change is in preparation for the final phases of integration, modernization, and rollout for the NSF NCAR Data Commons. This strategic initiative is transforming how we manage, integrate, and share data across NSF NCAR to support AI/ML readiness, interdisciplinary collaboration, and long-term scientific discovery.

The Data Commons will unify the RDA, CDG, and GDEX into a modernized, analysis-ready RDA. This merged system will provide a metadata-rich, standards-aligned foundation designed to make data more findable, accessible, interoperable, and reusable (FAIR). It supports everything from model development to AI training and enables the AI/ML roadmap by delivering consistent, high-quality inputs for next-generation science.

This work strengthens operational resilience, promotes efficiency, and lays the foundation for shared services, interoperable APIs, and unified data models—reducing silos and accelerating insights across disciplines.
