Dual crop coefficient modelling applied to the winter wheat–summer maize crop sequence in North China Plain: Basal crop coefficients and soil evaporation component

The dual crop coefficient (Kc) approach to estimate crop evapotranspiration (ETc) separately considers soil evaporation (E) and plant transpiration (T) by computing a soil evaporation coefficient (Ke) and a basal crop coefficient (Kcb), respectively, with Kc = Ke + Kcb. This approach may be more precise than the single Kc approach particularly when the crops incompletely cover the ground. The SIMDualKc model, which is adopted in this study, is...
