UKCP09: Annual Growing Season Length Time Series for the UK

UKCP09 time series data tracks the annual length of the growing season across the United Kingdom. The dataset was created with financial support from the UK's Department for Environment, Food and Rural Affairs (Defra) and is promoted by the UK Climate Impacts Programme. The growing season is defined as the period bounded by daily mean temperatures exceeding 5°C for more than five consecutive days and falling below 5°C for more than five consecutive days after July 1.

Use Cases

• Modeling climate change impacts on agriculture based on the annual growing season length metric.
• Analyzing long-term temperature trend effects on ecosystems based on the defined temperature threshold.
• Projecting future agricultural growing windows based on historical time series data.
• Correlating growing season length with crop yield data for UK regions.

Strengths

• Data is part of the authoritative UK Climate Projections (UKCP09) framework.
• Growing season is defined by a specific, reproducible temperature-based rule.

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 dated 2026-07-08.
