AgMIP GGCMI Phase II: Global Soybean Model Simulations Under Climate Scenarios

AgMIP's GGCMI Phase II CTWN-A archive contains output from pDSSAT model simulations for soybean. The dataset includes variables such as crop yield, biomass, and phenology dates from 31-year simulations. Simulations explore combinations of atmospheric CO2 levels, temperature offsets, water availability, and nitrogen inputs.

Use Cases

• Analyze soybean yield sensitivity based on manipulated CO2, temperature, water, and nitrogen levels.
• Model crop phenology shifts (planting, anthesis, maturity days) under different climate scenarios.
• Estimate irrigation water demand and evapotranspiration for soybean under varying water regimes.

Strengths

• Simulations cover a defined factorial design with 4 CO2 levels, 7 temperature offsets, 8 water levels, and 3 nitrogen levels.
• Output includes 7 key agricultural variables, including yield, biomass, and phenological dates.
• Dataset is part of a major international model intercomparison project (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.
