ISIMIP2a: Historical Climate Impact Simulations for Agriculture

ISIMIP2a simulation data provides multi-model historical climate impact projections for the agricultural sector from 1971 to 2010. The dataset includes outputs from 14 agricultural models such as CGMS-WOFOST, LPJmL, and pDSSAT, generated under the Inter-Sectoral Impact Model Intercomparison Project framework. It is intended for model evaluation and validation, particularly regarding extreme weather events and climate variability.

Use Cases

• Benchmarking agricultural impact models against observational data based on the described model evaluation focus.
• Analyzing the biophysical impacts of historical climate variability on crop yields using multi-model simulation outputs.
• Studying interactions between climate change impacts across sectors as facilitated by the ISIMIP framework.
• Improving estimates of socio-economic impacts of climate change at different warming levels using the provided historical scenarios.

Strengths

• Includes outputs from 14 distinct agricultural impact models, enabling multi-model comparison.
• Covers a defined historical period from 1971 to 2010 for consistent temporal analysis.
• Based on four common global observational climate datasets provided to all models, ensuring input consistency.
• Designed specifically for model evaluation and validation, particularly for extreme events.

Limitations

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