UKCP09: 5km Gridded Long-Term Average Days of Air Frost for the UK

UK gridded data for monthly average days of air frost. The dataset contains 12 files, one for each month, representing the 1961-1990 average period. It was 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 historical climate baselines based on the 1961-1990 average period.
• Analyzing seasonal frost patterns across the UK based on monthly average data.
• Validating climate projections using long-term observational averages.
• Studying spatial variability of frost days across a 5km resolution grid.

Strengths

• Provides a 30-year climatological baseline (1961-1990) for consistency.
• Data is gridded at a 5km spatial resolution for detailed geographic analysis.
• Contains 12 distinct files, one for each month, allowing for seasonal analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific 1961-1990 period.
