The wheat pilot team is led by Senthold Asseng, University of Florida, USA and Frank Ewert, University of Bonn, Germany. The wheat team met in 2010 in Amsterdam to initiate AgMIP-Wheat and at a 1-day work session at the Global AgMIP Workshop in Rome in 2012 to review results.
Collaborating scientists representing 27 wheat models intercompared their models for response to CO2, temperature, rainfall, and other factors at four sentinel sites representing variation in wheat productivity. They have an overall synthesis/analysis paper under review.
The AgMIP-Wheat team has follow-up plans to test their wheat models (30 models) against growth and yield responses observed in field experiments exposed to elevated temperature.
The activities planned involve two modeling activities:
- Blind test with minimal data simulating 45 temperature treatment combinations.
- Test of same treatments but with all anthesis and maturity data made available.
A workshop is planned at CIMMYT, Mexico, June 19-21, 2013 to allow modelers to compare results in detail and discuss possible improvements in simulating temperature responses.
