Update June 6: data access and file downloads have been restored.

Update June 4: data file download is currently unavailable due to maintenance on the NSF NCAR HPC systems. We will update this page when data access is restored.

Due to scheduled maintenance on the NSF NCAR HPC systems June 2–9, 2025, RDA data services might be operating in a degraded state. It is expected that data access and data file downloads will remain available. Processing of data subset requests, however, might be delayed due to limited computing resources during this maintenance period.

Please email RDA support at rdahelp@ucar.edu if you experience data access issues.
