A Study of the Influence of Environmental Factors on Water–Heat Exchange Process in Alpine Wetlands

open access: yesAtmosphere, 2023
Wetlands, which are composed of soil, vegetation and water, have sufficient water supply and are sensitive to climate change. This study analyzes the coupling degree between wetlands and atmosphere and discusses the influence of environmental factors ...

Regionalization of Vapor Pressure Deficit (VPD) in Spain [PDF]

open access: yes, 2020
<p>Vapor Pressure Deficit (VPD) is an atmospheric variable that represents the extra water vapor that air may contain prior to condensation. It is a relevant variable for climatology due to its consideration as a measure of ‘air dryness’, but also for hydrology and ecohydrology.

Reduced actual vapor pressure exerts a significant influence on maize yield through vapor pressure deficit amid climate warming

open access: yesInternational Journal of Biometeorology, 2023
Abstract Understanding the impact of climate warming on crop yield and its associated mechanisms is paramount for ensuring food security. Here, we conduct a thorough analysis of the impact of vapor pressure deficit (VPD) on maize yield, leveraging a rich dataset comprising temporal and spatial observations spanning 40 years across 31 maize ...

Thermodynamic constraints on effective energy and mass transfer and catchment function [PDF]

open access: yesHydrology and Earth System Sciences, 2012
Understanding how water, energy and carbon are partitioned to primary production and effective precipitation is central to quantifying the limits on critical zone evolution. Recent work suggests quantifying energetic transfers to the critical zone in the

Daily variations of water use with vapor pressure deficit in a plantation of I214 poplars. [PDF]

open access: yes, 2009
Daily rates of whole tree water use were measured in a homogeneous 7-year-old plantation over 84 days. Two trees were selected in the two most contrasting ends, i.e., with mean water table at -1.5 m and -3.5 m. Results showed that the mean tree water use

Rising vapor‐pressure deficit increases nitrogen fixation in a legume crop

open access: yesNew Phytologist, 2023
Summary Atmospheric vapor‐pressure deficit (VPD) is increasing in many regions and has a large impact on plant productivity. A VPD increase leads to raising transpiration rate (TR) and soil‐water demand, risking productivity penalties. Like water, nitrogen is critical to productivity, but the effect of VPD on legume nitrogen fixation is undocumented.

Novel applications of carbon isotopes in atmospheric CO2: what can atmospheric measurements teach us about processes in the biosphere? [PDF]

open access: yesBiogeosciences, 2011
Conventionally, measurements of carbon isotopes in atmospheric CO2 (δ13CO2) have been used to partition fluxes between terrestrial and ocean carbon pools.
