A third objective was to assess the contribution to evaporative demand trends that the four primary meteorological variables (being u; atmospheric humidity; radiation; and air temperature) made.
At the CONUS scale, the balance between precipitation and evaporative demand, and measures of geographic location were of high relative importance.
Hobbins and Huntington (2017) have provided an up-to-date account of evapotranspiration and evaporative demand.
The objective of this study is to investigate the limiting effects of soil moisture and evaporative demand on photosynthesis, and to understand its interactions with other hydrological processes.
Potential evapotranspiration (PET) was calculated from free water surface evaporative demand and MAP (J. K. Koelliker, personal communication).
Additional derived variables included degree day indices, frost free days, precipitation as snow, 30-year minimum and maximum temperature extremes, and evaporative demand indices.
Pan evaporation (Epan) is an indicator of atmospheric evaporative demand, and downward trends have been reported in many regions over the past several decades.
The lower the evaporative demand, the shallower were the depth of the evaporation front and the depth of salinisation, even for deep groundwater.
By parametrising a model of daily potential evaporation (Ep) at the forest floor we explore how vegetation and topography influence evaporative demand above the litter layer.
High temperatures drive non-linear increases in vapor pressure deficit (VPD), raising evaporative demand and concurrently depleting subsequent water supply21.
In a globally warming climate, observed rates of atmospheric evaporative demand have declined over recent decades.
