The countdown is on!
On Tuesday, September 9, the NSF NCAR Data Commons Initiative will relaunch the Research Data Archive (RDA, soon to be formerly known as RDA) as the Geoscience Data Exchange – Integrated Research Data Commons (GDEX), with updated access paths (e.g., /gdex/data/<Your_Dataset>).
This relaunch marks the unification of the Climate Data Gateway (CDG) and the Geoscience Data Exchange (GDEX) into a modernized repository that adheres to Findable, Accessible, Interoperable, and Reusable (FAIR) data principles. This new GDEX repository provides a single, unified foundation for Earth system science, empowering interdisciplinary collaboration and enabling AI/ML-ready data for future research. \
What's happening?
-
On Aug 25th, the DASH and RDA help desks merged into the NSF NCAR Research Data Help Desk (datahelp@ucar.edu| datahelp.ucar.edu), which will be monitored by Data Engineering and Curation Services staff. Legacy tickets and emails have been migrated to retain history.
-
On Aug 27, legacy CDG and GDEX were retired, as all data is now available in the unified RDA.
- On Sep 9, 2025, the RDA will officially relaunch as NSF NCAR's Geoscience Data Exchange – Integrated Research Data Commons (GDEX), complete with rebranding, updated websites, new data access paths (e.g., /gdex/data/<dataset>), and updated file naming conventions.
