Why does air passage over forest yield more rain? Examining the coupling between rainfall, pressure and atmospheric moisture content [PDF]

Journal of Hydrometeorology, 15, 411-426 (2014), 2013
The influence of forest loss on rainfall remains poorly understood. Addressing this challenge Spracklen et al. recently presented a pan-tropical study of rainfall and land-cover that showed that satellite-derived rainfall measures were positively correlated with the degree to which model-derived air trajectories had been exposed to forest cover.

Comparative analysis of 12 reference evapotranspiration methods for semi-arid regions (Spain)

Journal of Water and Climate Change, 2023
Evapotranspiration is one of the most significant variables used to determine runoff, hydrological balances, and climate change studies. In semi-arid conditions, there is a need to evaluate various alternatives to establish reference evapotranspiration ...

Estimation of Regional Evapotranspiration Using Remotely Sensed Land Surface Temperature. Part 2: Application of Equilibrium Evaporation Model to Estimate Evapotranspiration by Remote Sensing Technique [PDF]

, 1985
In a humid region like Japan, it seems that the radiation term in the energy balance equation plays a more important role for evapotranspiration then does the vapor pressure difference between the surface and lower atmospheric boundary layer. A Priestley-

Robust Model Predictive Control of Irrigation Systems with Active Uncertainty Learning and Data Analytics [PDF]

IEEE Transactions on Control Systems Technology, vol. 28, no. 4, pp. 1493-1504, 2020, 2018
We develop a novel data-driven robust model predictive control (DDRMPC) approach for automatic control of irrigation systems. The fundamental idea is to integrate both mechanistic models, which describe dynamics in soil moisture variations, and data-driven models, which characterize uncertainty in forecast errors of evapotranspiration and precipitation,

SSEBop Evapotranspiration Estimates Using Synthetically Derived Landsat Data from the Continuous Change Detection and Classification Algorithm

Remote Sensing
The operational Simplified Surface Energy Balance (SSEBop) model has been utilized to generate gridded evapotranspiration data from Landsat images. These estimates are primarily driven by two sources of information: reference evapotranspiration and ...

Behaviour of carbon dioxide and water vapour flux densities from a disturbed raised peat bog [PDF]

, 2002
Measurements of carbon dioxide and water vapour flux densities were carried out for a disturbed raised peat bog in the north of the Netherlands during an 18 month continuous experiment. Tussock grass (sp. Molinea caerulae) mainly dominated the vegetation

Global pattern and mechanism of terrestrial evapotranspiration change indicated by weather stations [PDF]

arXiv, 2023
Accurate estimation of global terrestrial evapotranspiration (ET) is essential to understanding changes in the water cycle, which are expected to intensify in the context of climate change. Current global ET products are derived from physics-based, yet empirical, models, water balance methods, or upscaling from sparse in situ observations.

The future of evapotranspiration : global requirements for ecosystem functioning, carbon and climate feedbacks, agricultural management, and water resources [PDF]

, 2017
The fate of the terrestrial biosphere is highly uncertain given recent and projected changes in climate. This is especially acute for impacts associated with changes in drought frequency and intensity on the distribution and timing of water availability.

Evapotranspiration of Pineapple in Hawaii [PDF]

Plant Physiology, 1965
The plants of the cerrado and caatinga ecological provinces of Brazil, the suggested original home of pineapple (3), have many and varied mechanisms whereby they have adapted to the frequent development of moisture stress. The pineapple plant presents a peculiarly interesting combination of those traits that have been proposed for xerophytic and sc ...
