Estimate canopy transpiration in larch plantations via the interactions among reference evapotranspiration, leaf area index, and soil moisture

•The Kcb for predicting daily canopy T based on ETo varies with REW and canopy LAI.•A daily T model coupling the effects of ETo, REW, LAI was developed for larch plantation.•This model can be used to quantify the independent effect of ETo, LAI, and REW on daily T.•This model is helpful for designing a precise integrated forest-water management.
