Dryland evapotranspiration from remote sensing solar-induced chlorophyll fluorescence: constraining an optimal stomatal model within a two-source energy balance model [PDF]

open access: yesarXiv, 2022
Evapotranspiration (ET) represents the largest water loss flux in drylands, but ET and its partition into plant transpiration (T) and soil evaporation (E) are poorly quantified, especially at fine temporal scales. Physically-based remote sensing models relying on sensible heat flux estimates, like the two-source energy balance model, could benefit from

Critical analysis of the contemporary methods for estimating reference evapotranspiration [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2012
Evapotranspiration is one of the most important processes within the hydrological cycle whose reliable assessment is essential in the planning and managing of land and water resources.

On a Lie algebraic structure associated with a non-linear dynamical system [PDF]

open access: yesarXiv, 2019
A family of Lie algebras of minimal dimension associated with vector fields that define a non-linear dynamical system is calculated. These Lie algebras contain the Heinsenberg algebra. An element that distinguishes these vector fields is called evapotranspiration function.

Predicting soil moisture conditions for arable free draining soils in Ireland under spring cereal crop production [PDF]

open access: yes, 2010
peer-reviewedTemporal prediction of soil moisture and evapotranspiration has a crucial role in agricultural and environmental management. A lack of Irish models for predicting evapotranspiration and soil moisture conditions for arable soils still ...

A signal of competitive dominance in mid-latitude herbaceous plant communities [PDF]

open access: yesarXiv, 2016
Understanding the main determinants of species coexistence across space and time is a central question in ecology. However, ecologists still know little about the scales and conditions at which biotic interactions matter and how these interact with the environment to structure species assemblages. Here we use recent theory developments to analyze plant

Effects of Spatial Heterogeneity in Rainfall and Vegetation Type on Soil Moisture and Evapotranspiration [PDF]

open access: yesarXiv, 2016
Nonlinear plant-scale interactions controlling the soil-water balance are generally not valid at larger spatial scales due to spatial heterogeneity in rainfall and vegetation type. The relationships between spatially averaged variables are hysteretic even when unique relationships are imposed at the plant scale.

Modelling of daily reference evapotranspiration using deep neural network in different climates [PDF]

open access: yesarXiv, 2020
Precise and reliable estimation of reference evapotranspiration (ET o ) is an essential for the irrigation and water resources management. ET o is difficult to predict due to its complex processes. This complexity can be solved using machine learning methods.

Mapping evapotranspiration variability over a complex oasis-desert ecosystem based on automated calibration of Landsat 7 ETM+ data in SEBAL [PDF]

open access: yes, 2019
Fragmented ecosystems of the desiccated Aral Sea seek answers to the profound local hydrologically- and water-related problems. Particularly, in the Small Aral Sea Basin (SASB), these problems are associated with low precipitation, increased temperature,
