Predicting the canopy conductance to water vapor of grapevines using a biophysical model in a hot and arid climate

Canopy conductance is a crucial factor in modelling plant transpiration and is highly responsive to water stress. The objective of this study is to develop a straightforward method for estimating canopy conductance (gc) in grapevines. To predict gc, this study combines stomatal conductance to water...
