UKCP09: 5km Gridded Annual Average Greatest 5-Day Precipitation Totals for the UK

UKCP09 5 km gridded data provides annual averages of the greatest 5-day precipitation total in millimeters. The dataset contains 12 files, one for each month, covering the 1961-1990 average period. It was created with financial support from the UK Department for Environment, Food and Rural Affairs (Defra) and is promoted by the UK Climate Impacts Programme.

Use Cases

• Modeling extreme rainfall patterns based on 5-day precipitation totals.
• Analyzing seasonal precipitation variability based on monthly gridded files.
• Assessing climate baseline conditions for the 1961-1990 period.
• Spatial analysis of precipitation extremes across the UK based on the 5km grid.

Strengths

• Data is gridded at a 5 km resolution, providing spatial detail.
• Covers a 30-year baseline period (1961-1990) for climate analysis.
• Contains 12 monthly files allowing for seasonal breakdown.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the 1961-1990 period.
