Due to scheduled maintenance on the NSF NCAR HPC systems, the following GDEX data services will be unavailable September 1, 2026:

• Data access and file download for all datasets and completed subset requests
• Globus transfer for all datasets and completed subset requests
• Dataset subset processing and data format conversion. Data subset requests will be accepted during the downtime, but processing will not proceed until after HPC systems are returned to service.

We expect all services to be back online on September 2, 2026.
