UKCP09: 1961-1990 Baseline Averages for Heating Degree Days Across UK Regions

1961-1990 long-term climate baseline averages for heating degree days across 14 UK administrative regions and 23 river basins. The data was created with financial support from the UK Department for Environment, Food and Rural Affairs (Defra) and promoted by the UK Climate Impacts Programme. Each regional value is an average of the underlying 5 x 5 km grid cell values.

Use Cases

• Modeling historical heating energy demand based on regional heating degree day averages.
• Establishing climate change baselines for UK administrative regions using the 1961-1990 reference period.
• Comparing climatic conditions between different UK river basins using annual average metrics.
• Calibrating building energy simulation models with long-term regional climate normals.

Strengths

• Covers a 30-year climate baseline period (1961-1990).
• Provides data for 14 administrative regions and 23 river basins.
• Values are derived from a spatial average of 5 x 5 km grid cells.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified despite the listed last update.
