Canopy conductance

Canopy conductance, commonly denoted , is a dimensionless quantity characterizing radiation distribution in tree canopy. By definition, it is calculated as a ratio of daily water use to daily mean vapor pressure deficit (VPD).[1] Canopy conductance can be also experimentally obtained by measuring sap flow and environmental variables.[2] Stomatal conductance may be used as a reference value to validate the data, by summing the total stomatal conductance of all leaf classes within the canopy.[3]
