When Does Vapor Pressure Deficit Drive or Reduce Evapotranspiration? [PDF]

Journal of Advances in Modeling Earth Systems, 2019
Increasing vapor pressure deficit (VPD) increases atmospheric demand for water. While increased evapotranspiration (ET) in response to increased atmospheric demand seems intuitive, plants are capable of reducing ET in response to increased VPD by closing

Large influence of atmospheric vapor pressure deficit on ecosystem production efficiency [PDF]

Nature Communications, 2022
D isentangling the respective effects of soil moisture (SM) and vapor pressure deficit (VPD) on ecosystem production is challenging but essential for understanding terrestrial carbon uptake in response to dryness stress.

Drought-Induced Responses in Maize under Different Vapor Pressure Deficit Conditions [PDF]

Plants, 2022
Water stress in plants depends on the soil water level and the evaporative demand. In this study, the physiological, biochemical, and molecular response of maize were examined under three evaporative demand conditions (low—1.00 kPa, medium—2.2 kPa, and ...

Drastic increase in the magnitude of very rare summer-mean vapor pressure deficit extremes [PDF]

Nature Communications
Summers with extremely high vapor pressure deficit contribute to crop losses, ecosystem damages, and wildfires. Here, we identify very rare summer vapor pressure deficit extremes globally in reanalysis data and climate model simulations, and quantify the

Increased atmospheric vapor pressure deficit reduces global vegetation growth. [PDF]

Sci Adv, 2019
Global vegetation greening trend stalled after the late 1990s due to increased atmospheric water demand. Atmospheric vapor pressure deficit (VPD) is a critical variable in determining plant photosynthesis.

Disentangling the effects of vapor pressure deficit on northern terrestrial vegetation productivity. [PDF]

Sci Adv, 2023
The impact of atmospheric vapor pressure deficit (VPD) on plant photosynthesis has long been acknowledged, but large interactions with air temperature (T) and soil moisture (SM) still hinder a complete understanding of the influence of VPD on vegetation ...

Warming-induced vapor pressure deficit suppression of vegetation growth diminished in northern peatlands [PDF]

Nature Communications, 2023
Recent studies have reported worldwide vegetation suppression in response to increasing atmospheric vapor pressure deficit (VPD). Here, we integrate multisource datasets to show that increasing VPD caused by warming alone does not suppress vegetation ...

Projected U.S. drought extremes through the twenty-first century with vapor pressure deficit [PDF]

Scientific Reports, 2022
Global warming is expected to enhance drought extremes in the United States throughout the twenty-first century. Projecting these changes can be complex in regions with large variability in atmospheric and soil moisture on small spatial scales.

Transpiration response to soil drying versus increasing vapor pressure deficit in crops: physical and physiological mechanisms and key plant traits. [PDF]

J Exp Bot, 2023
The water deficit experienced by crops is a function of atmospheric water demand (vapor pressure deficit) and soil water supply over the whole crop cycle.
