NOAA UFS: Subseasonal to Seasonal Weather Reforecast Prototypes

Unified Forecast System (UFS) reforecast data from experimental atmosphere-ocean coupled model prototypes version 5 through 8. The dataset includes major weather variables for atmosphere, land, ocean, sea ice, and ocean waves. It was produced by the UFS Research to Operations project for the National Weather Service and NOAA.

Use Cases

• Evaluating subseasonal to seasonal forecast skill based on reforecast data from multiple model prototypes.
• Analyzing coupled atmosphere-ocean interactions based on the included weather variables.
• Benchmarking experimental weather models against operational systems for research-to-operations transition.

Strengths

• Data from four distinct experimental model prototypes (versions 5, 6, 7, and 8) for comparison.
• Includes major weather variables across five Earth system components: atmosphere, land, ocean, sea ice, and ocean waves.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
