The contribution was determined by sequentially removing one of the nine GGCMs from the ensemble of GGCMs at each grid point, and then comparing the GGCM-induced uncertainty share of projected yield changes between the full GGCM model set and the set without the particular model. A positive change indicates that including a particular model increased the GGCM-induced uncertainty share. A negative contribution change indicates that using this model decreased the GGCM-induced uncertainty share. GGCM is global gridded crop model.
