Interannual variation of the Bowen ratio in a subtropical coniferous plantation in southeast China, 2003-2012. [PDF]
PLoS ONE, 2014 The interannual variation of the Bowen ratio, through its effect on the warming extent of available energy to the ecosystem land surface air, heavily influences the ecosystem microclimate and affects the hydrological cycle at both regional and global ...

Modified formula for estimating the Bowen ratio – description of the determination procedure [PDF]
Acta Scientiarum Polonorum. Formatio CircumiectusAim 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 ...

Emergent constraints on the hydrological impacts of land use and land cover change [PDF]
Nature CommunicationsLand use and land cover changes have substantial effects on the terrestrial water cycle, but their sign and magnitude remain elusive at large scales. State-of-the-art Earth system models disagree on how these changes affect terrestrial evapotranspiration.

A new method to measure Bowen ratios using high-resolution vertical dry and wet bulb temperature profiles [PDF]
Hydrology and Earth System Sciences, 2014 The Bowen ratio surface energy balance method is a relatively simple method to determine the latent heat flux and the actual land surface evaporation. The Bowen ratio method is based on the measurement of air temperature and vapour pressure gradients. If

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 ...

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 ...

Modeling potential evapotranspiration based on energy balance
Shui kexue jinzhan, 2022 To investigate a more accurate method for potential evapotranspiration estimation under climate change, three sets of experiments were conducted using small lysimeters at Wudaogou experimental station on the Huaibei Plain (China), and a new model of ...
