UKCP09: 5km Gridded Mean Sea-Level Pressure Averages for the UK

12 monthly files provide mean sea-level pressure data for the UK, averaged over the 1961-1990 period on a 5km grid. The Met Office created this dataset with support from the UK Department for Environment, Food and Rural Affairs (Defra). The data is promoted by the UK Climate Impacts Programme as part of the UK Climate Projections (UKCP09).

Use Cases

• Modeling historical atmospheric pressure patterns based on the 5km gridded data.
• Analyzing seasonal pressure variations based on the 12 monthly average files.
• Establishing a 1961-1990 climate baseline for the UK based on the long-term average period.
• Studying geospatial climate trends based on the gridded data format.

Strengths

• Data covers a 30-year climatological reference period (1961-1990).
• Spatial resolution is specified as a 5km grid.
• Dataset consists of 12 files, one for each month.

Limitations

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