Response of ecosystem intrinsic water use efficiency and gross primary productivity to rising vapor pressure deficit

Response of ecosystem intrinsic water use efficiency and gross primary productivity to rising vapor pressure deficit

Elevated vapor pressure deficit (VPD) due to drought and warming is well-known to limit canopy stomatal and surface conductance, but the impacts of elevated VPD on ecosystem gross primary productivity (GPP) are less clear. The intrinsic water use efficiency (iWUE), defined as the ratio of carbon (C)...
