UKCP09: 5km Gridded Mean Daily Maximum Temperature Averages

1961-1990 monthly averages for mean daily maximum temperature across the UK. The dataset contains 12 files, one for each month, representing a long-term climatological baseline. It was created with support from the UK Department for Environment, Food and Rural Affairs (Defra) and is promoted by the UK Climate Impacts Programme.

Use Cases

• Modeling historical climate baselines based on the 1961-1990 average period.
• Analyzing spatial temperature patterns across the UK based on the 5km gridded data.
• Comparing seasonal temperature variations based on the 12 monthly average files.
• Assessing climate change impacts by using this dataset as a historical reference point.

Strengths

• Data represents a 30-year climatological baseline (1961-1990).
• Spatial coverage is provided on a consistent 5km grid across the UK.
• The dataset consists of 12 distinct files, one for each calendar month.

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 1961-1990 reference period.
