UKCP09: 1961-1990 Winter Heatwave Duration Averages for UK Regions

UKCP09 regional baseline averages for winter heatwave duration from 1961 to 1990. The Met Office produced these values by averaging 5 x 5 km grid cells within 14 administrative regions and 23 river basins. Data is provided as space-delimited text files, supported by the UK Department for Environment, Food and Rural Affairs (Defra).

Use Cases

• Establishing historical climate baselines based on the 1961-1990 reference period mentioned in the description
• Analyzing regional variations in winter heatwave duration across UK administrative regions and river basins
• Projecting future climate impacts using the UKCP09 framework referenced in the description

Strengths

• Provides a defined 30-year climate baseline (1961-1990) for consistency
• Covers two distinct spatial units: 14 administrative regions and 23 river basins
• Data is derived from a high-resolution 5 x 5 km grid

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
