UKCP09: Greatest 5-Day Precipitation Averages for UK Regions and River Basins, 1961-1990

UKCP09 provides long-term average precipitation data for a 30-year climate baseline. The dataset contains annual averages for the greatest 5-day precipitation total across 14 UK administrative regions and 23 river basins. Data was produced with support from the UK Department for Environment, Food and Rural Affairs and is promoted by the UK Climate Impacts Programme.

Use Cases

• Analyze regional climate extremes based on the greatest 5-day precipitation total variable.
• Compare precipitation patterns between administrative regions and river basins based on the 14 and 23 spatial units.
• Establish a historical climate baseline for impact studies based on the 1961-1990 reference period.

Strengths

• Data covers a 30-year climate baseline period from 1961 to 1990.
• Values are provided for two distinct spatial frameworks: 14 administrative regions and 23 river basins.
• Regional values are derived from an average of underlying 5 x 5 km grid cell data.

Limitations

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