UKCP09: 1961-1990 Baseline Mean Relative Humidity for UK Regions and River Basins

UK regional and river basin averages for mean relative humidity, calculated for the 1961-1990 climate baseline. The data was created with financial 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 the underlying 5 x 5 km grid cell values.

Use Cases

• Analyzing seasonal humidity patterns across UK regions based on the provided monthly averages.
• Establishing a historical climate baseline for hydrological or agricultural models based on the 1961-1990 period.
• Comparing humidity trends between administrative regions and river basins based on the two provided spatial aggregations.

Strengths

• Provides data for a standard 30-year climate baseline period (1961-1990).
• Covers two distinct spatial aggregations: 14 administrative regions and 23 river basins.
• Values are derived from a consistent 5 x 5 km grid, suggesting a standardized spatial methodology.

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.
