About the Geoscience Data Exchange
The Geoscience Data Exchange (GDEX), managed by the Data Engineering and Curation Section (DECS) of the Computational and Information Systems Laboratory (CISL) at NSF NCAR, contains a large collection of meteorological and oceanographic observations, operational and reanalysis model outputs, integrated with NSF NCAR High Performance Compute resources to support atmospheric and geosciences research.
Mission Statement
The DECS mission is to support atmospheric and related sciences research by maintaining and developing the Geoscience Data Exchange, and reinforcing its utility with expert consulting. It is realized by:
- Managing a heterogeneous archive constructed over a 50+ year time period
- Supporting long-term preservation of irreplaceable data
- Acquiring data that extends and stewards essential ongoing datasets
- Expanding GDEX with new community reference datasets
- Implementing evolved IT functionality to enhance user data discovery and access
- Providing data management support to NCAR researchers
The DECS mission statement is motivated by the NCAR and NSF mission components.

GDEX is proud to be a CoreTrustSeal Certified Repository and a regular member of the World Data System. CoreTrustSeal is an international, community based, non-governmental, and non-profit organization promoting sustainable and trustworthhy data infrastructures. For transparency, CoreTrustSeal publishes a public version of each certified repository's application, including the GDEX application.
