AgMIP GGCMI Phase II: Winter Wheat Crop Model Simulations Under Climate Scenarios

AgMIP's GGCMI Phase II archive contains 31-year simulation outputs for winter wheat from the pDSSAT model. Variables include crop yield, biomass, phenology dates, and water use under manipulated climate and management conditions. Joshua Elliott at the University of Chicago produced this data as part of a global crop model intercomparison project.

Use Cases

• Train models to predict crop yield based on climate and management scenarios described in the data.
• Analyze the sensitivity of crop phenology (planting, anthesis, maturity days) to temperature and water offsets.
• Assess irrigation water requirements and evapotranspiration under different climate change projections.
• Benchmark crop model performance against other models in the AgMIP intercomparison framework.

Strengths

• Simulations cover a wide experimental design with 4 CO2 levels, 7 temperature offsets, 8 water regimes, and 3 nitrogen levels.
• Output includes multiple key agricultural variables such as yield, biomass, and phenological dates.
• Data is part of a major, standardized international model intercomparison effort (AgMIP GGCMI).

Limitations

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