UKCP09: Monthly Mean Vapour Pressure Grids for the UK

Monthly gridded datasets of mean vapour pressure at a 5 x 5 km resolution covering the United Kingdom. The data is provided in 10-year blocks and is formatted as ESRI ASCII grid text files for use in GIS software. Created with support from the UK Department for Environment, Food and Rural Affairs (Defra) and promoted by the UK Climate Impacts Programme.

Use Cases

• Modeling climate change impacts based on monthly vapour pressure data.
• Analyzing long-term humidity trends based on 10-year data blocks.
• Creating visualizations of atmospheric moisture distribution across the UK based on the 5 km gridded data.
• Integrating climate variables for regional adaptation planning based on UKCP09 projections.

Strengths

• Data is provided at a high spatial resolution of 5 x 5 km.
• Datasets are structured in 10-year blocks for longitudinal analysis.
• Files are formatted as ESRI ASCII grids for direct use in common GIS software.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Access requires registration on the Met Office website.
