2.1. Gridded crop models description
We use two mechanistic gridded crop models (GCR) to evaluate the change in soybean productivity after climate change (therefore reducing the uncertainty related to model induced bias): the Light-Use Efficiency Model—LUE (Costa et al., 2009 and Oliveira et al., 2013) and the Integrated Model of Land Surface Processes (INLAND, Costa et al., manuscript in preparation). Even though the phenological processes in both models are a function of temperature (accumulated growing degree-days), they differ in complexity.
