UKCP09: 1961-1990 Baseline Cooling Degree Days for UK Regions and River Basins

UKCP09 provides long-term average cooling degree days for a 30-year climate baseline. The Met Office produced these regional averages for 14 administrative regions and 23 river basins, with financial support from Defra. Each regional value is derived from an average of underlying 5 x 5 km grid cell values.

Use Cases

• Modeling historical energy demand for air conditioning based on cooling degree day metrics
• Comparing climate baseline conditions across UK administrative regions and river basins
• Calibrating climate projection models against the 1961-1990 reference period

Strengths

• Data covers a 30-year climate baseline period (1961-1990)
• Values are provided for 14 administrative regions and 23 river basins
• Regional averages are calculated from underlying 5 x 5 km grid data

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
