UKCP09: 5km Gridded Annual Average Growing Season Length in Days

12 files provide annual averages for growing season length in days across the UK on a 5km grid. The data covers the 1961-1990 average period, with one file for each month. The Met Office created this dataset with support from the UK Department for Environment, Food and Rural Affairs (Defra).

Use Cases

• Modeling climate change impacts on agriculture based on growing season length data.
• Analyzing spatial patterns of growing conditions across the UK based on the 5km gridded format.
• Calibrating crop yield models using historical climate baseline data from the 1961-1990 period.
• Studying seasonal variations in growing season length based on the monthly average files.

Strengths

• Data is provided on a consistent 5km spatial grid covering the UK.
• Includes 12 files representing monthly averages for a 30-year baseline period (1961-1990).
• Created by the authoritative UK Met Office with support from the national government department Defra.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
