Simulated Crop Biomass and Soil Variables for Loess Plateau 1983-2049

1983-2015 historical and 2015-2049 future scenario data from the SPACSYS model includes simulated daily dry matter accumulation for winter wheat and maize, soil water content by layer, and soil organic carbon stocks. The model was validated using observed crop yields from a historic experimental site on China's Loess Plateau.

Use Cases

• Analyze daily soil water content dynamics across different soil layers under historical and future climate scenarios.
• Model the relationship between soil organic carbon stocks in topsoil/subsoil layers and final crop dry matter yield.
• Forecast daily dry matter accumulation in leaves, stems, and grains for winter wheat and maize under various climatic projections to 2049.
• Validate crop growth models using the provided historical observed yield data for wheat (1993-2004) and maize (1983-2015).

Strengths

• Provides multi-decade temporal coverage from 1983 through future projections to 2049.
• Includes model validation using observed crop yield data from a specific experimental site.
• Contains simulated data for multiple critical agricultural variables: crop dry matter, soil water, and soil organic carbon.

Limitations

• Data is entirely model-generated simulation, not direct field measurements, introducing model dependency and potential bias.
• Geographic scope is limited to a single historic experimental site on the Loess Plateau, China.
