UKCP09: Annual Summer Coldwave Duration Gridded Data for the UK

Annual gridded datasets of summer coldwave duration values for the United Kingdom. The data represents the sum of days where the daily minimum temperature is more than 3°C below the 1961–1990 daily normal for at least five consecutive days during May to October. The datasets were created with financial support from the UK Department for Environment, Food and Rural Affairs (Defra) and are promoted by the UK Climate Impacts Programme.

Use Cases

• Modeling climate change impacts based on annual coldwave duration metrics.
• Analyzing trends in summer temperature extremes based on gridded historical data.
• Assessing regional climate vulnerability based on deviations from 1961-1990 temperature norms.

Strengths

• Data is gridded, providing spatial coverage for the UK.
• Based on a defined 1961–1990 baseline period for consistent anomaly calculation.
• Created with support from the UK government department Defra.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Access requires registration on the Met Office website.
