Micro-level spatial variability and temporal trends in reference evapotranspiration (ETo) at a semi-arid tropical station

open access: yesJournal of Agrometeorology, 2010
Micro-level spatial variability and temporal trends in annual and seasonal (weeks 23-39) reference evapotranspiration (ETo) were analyzed across three locations in Hyderabad.

Geospatial interpolation of reference evapotranspiration (ETo) in areas with scarce data: case study in the South of Minas Gerais, Brazil

open access: yesRevista Ambiente & Água, 2012
The reference evapotranspiration is an important hydrometeorological variable; its measurement is scarce in large portions of the Brazilian territory, what demands the search for alternative methods and techniques for its quantification.

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,

Reference crop evapotranspiration over Greece

open access: yesAgricultural Water Management, 1991
Abstract Monthly evapotranspiration (ET) estimates for 31 locations in Greece are calculated by the Penman, Priestley-Taylor and Thornthwaite methods. The analysis of 27 years of routine meteorological data indicates that annual amounts of ET obtained by Priestley-Taylor or Thornthwaite methods do not generally agree very well with Penman ET (ETPEN ...

Multi-decadal trends in global terrestrial evapotranspiration and its components [PDF]

open access: yes, 2016
Evapotranspiration (ET) is the process by which liquid water becomes water vapor and energetically this accounts for much of incoming solar radiation. If this ET did not occur temperatures would be higher, so understanding ET trends is crucial to predict

Performance Assessment of M5 Tree Model and Genetic Programming in Tabriz Station Reference Evapotranspiration Modeling [PDF]

open access: yesمهندسی منابع آب, 2017
Evapotranspiration has a main role in water budget assessment and management. In plant water requirements and evapotranspiration volume calculation, firstly reference evapotranspiration (ET0) have to be computed and then plant water requirements can be ...

A model of correction indexes determination for Virginia type tobacco on the basis of field measured ETP [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade), 2009
Numerous methods of calculating ET0 and ETP offer a great practical possibility for their application, but in order to improve their efficiency it is necessary to check them in particular regions.

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

open access: yes, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...

Empirical methods for reference evapotranspiration estimation

open access: yesScientia Agraria Paranaensis, 2020
The reference evapotranspiration (ETo) is a parameter applied in meteorological, climatological and hydrological studies being of great importance for the planning, management and management of water resources. Due to the need for knowledge about the loss of water from vegetated surfaces, researchers have developed a variety of methods for estimating ...
