UKCP09: 1961-1990 Baseline Monthly Mean Sea-Level Pressure for UK Regions

1961-1990 long-term averages of monthly mean sea-level pressure for 14 UK administrative regions and 23 river basins. The data was produced by the UK Met Office with support from Defra and is part of the UK Climate Projections (UKCP09). Each regional value is an average of the underlying 5 x 5 km grid cell values.

Use Cases

• Analyzing seasonal pressure patterns across UK regions based on the 12 monthly averages per region.
• Establishing historical climate baselines for impact modeling based on the 1961-1990 reference period.
• Comparing atmospheric conditions between administrative regions and river basins based on the two provided spatial aggregations.
• Validating or calibrating climate models using long-term averaged observational data.

Strengths

• Covers a standard 30-year climate baseline period (1961-1990).
• Provides data for two distinct spatial aggregations: 14 administrative regions and 23 river basins.
• Values are derived from a high-resolution underlying grid of 5 x 5 km cells.

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• Data freshness should be verified; the projection set (UKCP09) has been superseded by newer versions.
