Modified formula for estimating the Bowen ratio – description of the determination procedure [PDF]

Acta Scientiarum Polonorum. Formatio Circumiectus
Aim of the study: One way of estimating evapotranspiration is to use the heat balance structure of active surface. Material and methods: The paper shows how to derive a formula estimating the Bowen ratio by using measurement data of heat balance ...

GUIDELINES FOR VALIDATING BOWEN RATIO DATA [PDF]

Transactions of the ASAE, 2003
For a variety of reasons, the measurement of latent heat flux using the Bowen ratio method can sometimes result in erroneous data. This study provides guidelines for detecting erroneous Bowen ratio data and illustrates the application of these guidelines by comparing Bowen ratio and lysimeter data collected over grass and alfalfa in southern Idaho ...

Bowen‐Ratio Comparisons with Lysimeter Evapotranspiration [PDF]

Agronomy Journal, 1997
AbstractWater use in agriculture by different cropping systems is of interest in determining crop water use efficiency of different tillage practices that will lead to reduced crop production risk. Lysimeters are considered the standard for evapotranspiration (ET) measurements; however, these units are often not replicated and are few in number at any ...

Surface-Spin-Induced Magnetic Loss Enhancement in Ultralight Electromagnetic Absorbers. [PDF]

Adv Sci (Weinh)
Fe3O4 nanoparticles with different hollow rates were synthesized to demonstrate the key role of surface moment in magnetic loss process. Using the same volume filling ratio, the 54.1% hollow Fe3O4 absorber represents about 20% enhancement in the imaginary part (μ'') than solid particles due to the coexisting magnetic resonance of inside and outside ...

Energy Distribution Characteristics and Environmental Impact Factors in Different Regions of the Summer Monsoon Transition Zone

Frontiers in Environmental Science, 2022
The summer monsoon transitional zone is a typical transitional ecosystem that is, also ecologically fragile. It is critical to explore the land surface energy balance and the water and heat transfer processes in this region for water resource management.

Bowen ratio and evapotranspiration dynamics of oil palm

International Journal of Tropical Drylands, 2023
Abstract. Asyura MF, June T, Salmayenti R. 2023. Bowen ratio and evapotranspiration dynamics of oil palm. Intl J Trop Drylands 7: 37-45. To optimize its biophysical processes, plant needs water and this requirement can be quantified as Evapotranspiration (ET).

Evapotranspiration of riparian ecosystems and irrigated cotton agriculture at the middle reaches of the Tarim River, Xinjiang, China

Central Asian Journal of Water Research, 2017
In the steppes, semi-deserts, and deserts of Central Asia the most productive ecosystems are riparian ecosystems like forests and shrublands. Rivers also serve as the water source for irrigation so that the major settlements and oases of the region are ...
