Vegetational Correlations with Vapor Pressure Deficit and Relative Humidity
American Midland Naturalist, 1942Ecologists have long attempted to single out critical environmental factors for use in distributional, successional, and other ecological studies. Temperature and relative humidity have been foremost in consideration. In recent years the importance of relative humidity, and even of temperature, has been minimized.

13C content of ecosystem respiration is linked to precipitation and vapor pressure deficit
Oecologia, 2002Variation in the carbon isotopic composition of ecosystem respiration (δ13CR) was studied for 3 years along a precipitation gradient in western Oregon, USA, using the Keeling plot approach. Study sites included six coniferous forests, dominated by Picea sitchensis, Tsuga heterophylla, Pseudotsuga menziesii, Pinus ponderosa, and Juniperus occidentalis,

EFFECT OF VAPOR PRESSURE DEFICIT ON SPINACH GROWTH UNDER HYPOBARIC CONDITIONS
Acta Horticulturae, 1996The effect of vapor pressure deficit (VPD) of air during photoperiod on spinach growth under low total pressure was examined. Spinach plants grown under atmospheric pressure were transplanted into a pressure-reduced growth chamber and cultured hydroponically for eight days.

Thermodynamic controls on vapor pressure deficit during droughts
Vapor pressure deficit (VPD) is widely used as a measure of atmospheric dryness and evaporative demand in drought studies, yet its interpretation as an independent drought driver remains unclear because of its close coupling to soil-moisture and radiation.Sarosh Ghausi +2 more

Analysis of methods for estimating vapor pressure deficits and relative humidity
Agricultural and Forest Meteorology, 1996Vapor pressure deficit (VPD) is one of the critical variables that drives evapotranspiration (ET), and is of fundamental importance in crop models. The objectives of this work were to compare the methods used to calculate VPD, and to propose several different ways of calculating VPD at daily and diurnal time scales depending on the available data.

Ecology, 1940
The repeated solution of more or less involved equations by actual computation, with or without the use of tables, is being advantageously replaced in many fields by mechanical solution through the use of nomograms. In these devices the mathematical equation that defines the relationship existing between a set of variables is represented by a geometric

Downscaling Vapor Pressure Deficit across Complex Forested Terrain
Journal of Applied Meteorology and ClimatologyAbstract The forest microclimate shapes many aspects of forest functioning, including plant regeneration and wildfire occurrence. In complex landscapes with varying terrain, the forest microclimate varies at fine spatial scales (10–100 m2). However, accurately mapping this variation remains challenging.
