UKCP09: Monthly Mean Sea-Level Pressure Grids for the UK

Gridded datasets of monthly mean sea-level pressure values for the United Kingdom, created as part of the UK Climate Projections 2009 (UKCP09). The data is provided at a 5 x 5 km resolution in 10-year blocks and is intended to support research into climate change impacts and adaptation. The Met Office generated this resource with financial support from the UK Department for Environment, Food and Rural Affairs (Defra).

Use Cases

• Analyzing long-term atmospheric pressure trends based on monthly gridded data.
• Modeling climate change impacts on regional weather patterns based on UK-wide coverage.
• Validating climate projection models using the 5 km resolution observational grids.
• Studying seasonal and interannual variability in mean sea-level pressure for the UK.

Strengths

• Data is provided at a consistent 5 x 5 km spatial resolution across the UK.
• Datasets are organized in monthly grids downloadable in 10-year blocks, facilitating temporal analysis.
• The grid text files use a format compatible with ESRI GIS software like ArcView for direct import.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last metadata update is 2026-07-08 13:33:21.004234.
