UKCP09: UK Regional Monthly Minimum Temperature Averages, 1961-1990 Baseline

1961-1990 baseline monthly averages for mean daily minimum temperature across 14 UK administrative regions and 23 river basins. The data was produced by the Met Office with support from the UK Department for Environment, Food and Rural Affairs (Defra) and promoted by the UK Climate Impacts Programme. Each regional value is an average of 5 x 5 km grid cell values, provided as space-delimited text files requiring registration on the Met Office website.

Use Cases

• Establishing historical climate baselines for UK regions based on the 1961-1990 period.
• Analyzing seasonal temperature patterns using monthly average values.
• Comparing temperature trends between administrative regions and river basins.
• Validating climate models against long-term observed temperature averages.

Strengths

• Covers a 30-year climate baseline period (1961-1990).
• Provides data for two distinct geographic groupings: 14 administrative regions and 23 river basins.
• Values are 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.
• Row count is unknown, which may limit suitability assessment.
