UKCP09: Regional Coldwave Duration Averages for Summer Months

1961-1990 baseline averages for summer coldwave duration across 14 UK administrative regions and 23 river basins. The data was produced by the Met Office with financial support from the UK Department for Environment, Food and Rural Affairs (Defra). Each regional value is an average of the underlying 5 x 5 km grid cell values.

Use Cases

• Analyze regional climate variability based on summer coldwave duration metrics.
• Compare baseline climate conditions between administrative regions and river basins.
• Model historical climate extremes using long-term average data from the 1961-1990 period.

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 5 x 5 km resolution grid.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-07-08.
