The model is described in the PhD thesis of S. Nonhebel: 'The importance of weather data in crop growth simulation models and assessment of climatic change effects', Wageningen Agricultural University, 1993. This version available is the one used in chapter 7 of the thesis, a detailed description is found in chapter 6. The model is developed to simulate the effects of increased atmospheric CO2 concentration on wheat yields in Europe solely or in combination with changes in air temperature. The model simulates both potential and water-limited production of a wheat crop and is based on SUCROS87. For further description is referred to data sheets of SUCROS1* and SUCROS2* . The model is also used in: Nonhebel, S., 1993. The effect of changes in temperature and CO2 concentration on simulated spring wheat yields in The Netherlands. Climatic Change 24: 311-329.
