Canopy conductance : ウィキペディア英語版 | 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).〔(【引用サイトリンク】title=Canopy conductance of estate tea in Kenya )〕 Canopy conductance can be also experimentally obtained by measuring sap flow and environmental variables. 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.
